Description of this part for the microscope.

colorless filter is placed (presumably "zero glass").

This particular specimen comes from a Zeiss Universal microscope, but Zeiss uses the same slide standard in other models as well, e.g., Photomicroscope (Phomi) and Ultraphot.

These slides were produced in various versions, differing in minor details but with no difference in function.

Such stages are interchangeable and can be installed in many Zeiss microscopes, however they are most commonly used in the following microscopes:
- Zeiss Universal
- Zeiss Photomicroscope (so-called Zeiss Phomi)
- Zeiss Ultraphot

In the photo gallery there are detailed images of this element together with dimensions. Additionally, in the last photo an arrow indicates which part is being referred to and where it is located in the stage, in order to clearly identify this component.

a Zeiss microscope stage on which no model designation was provided. Over the years during which Zeiss produced such stages, numerous variants were created (I have personally seen five, for example Zeiss P/N 47 34 28 - 9901 https://www.microscopeparts.eu/microscope/282). Despite this variety, the construction is largely consistent, and most parts are identical.
It is therefore highly likely that the part shown and offered here is compatible with many variants of such microscope stages.

Such stages are interchangeable and can be installed in many Zeiss microscopes, however they are most commonly used in the following microscopes:
- Zeiss Standard 14
- Zeiss Standard 16
- Zeiss Standard GFL

in microscopes:
- Zeiss Phomi (Zeiss Photomicroscope)
- Zeiss Ultraphot
- Zeiss Universal
and others, most often the Zeiss Standard series.

Description of this part for the microscope.

This particular screw was removed from a Zeiss Standard 14 microscope, but it will most likely fit most models of the Standard series, for example:
- Zeiss Standard GFL
- Zeiss Standard 16
- Zeiss Standard WL 89
- Zeiss Standard Universal
- Zeiss Standard Photomicroscope
- Zeiss Ultraphot

Note - over the years, Zeiss microscopes (or the same microscopes sold under the Zeiss-Winkel name or under the Opton brand), especially simpler models such as the Zeiss Standard Junior, used different types of head-retaining screws. These were not necessarily spring-loaded screws - in some cases ordinary threaded clamping screws were used instead.

Before deciding to replace the screw in a microscope, it is best to carefully compare its appearance and dimensions with the photographs in the gallery or ask a question on the forum https://www.mikroskopie-forum.de/

supply:
Manufacturer: Carl Zeiss
Model: VWH 200/C 250 f-3b
Manufacturer P/N: 39 26 34 (also written as 392634)
Supported fluorescence lamps: HBO 200 W/4 L1, HBO 200 W/4 L2 and CSI 250W
Input voltage: 220 V - 240 V
Power rating: 900 VA

This power supply was supplied as standard with Zeiss Photomicroscope microscopes (commonly known as the Zeiss Phomi) whenever the microscope was equipped with an HBO high-pressure fluorescence illuminator (also referred to as a burner or lamp).

The same or very similar illuminators with identical electrical specifications were used in, among others:
- Zeiss Standard WL
- Zeiss Photomicroscope
- Zeiss Universal
- Zeiss Ultraphot
- such illuminators were also occasionally adapted for use with other microscope models, including those made by other manufacturers
Therefore, this power supply is suitable for all of the applications listed above.

Please note: the last photograph shows a dent in the housing. This does not affect the operation of the unit. Since the dent is located on the underside of the housing, it is not visible when the power supply is standing on a laboratory bench.

IMPORTANT: Always protect your eyesight when working with UV illumination. Never exceed the recommended service life of HBO high-pressure lamps. Always follow the operating instructions supplied with the fluorescence illuminator.

Zeiss Universal
- Zeiss Photomicroscope (the so-called Zeiss Phomi)
- Zeiss Ultraphot

This holder allows interchangeable microscope stages to be mounted, meaning stages that are not screwed directly to the microscope stand. It also features two centering screws.

This holder consists of two parts:

Description of this part for the microscope.

In Carl Zeiss Standard series microscopes (with the exception of the Standard Junior teaching microscope), the condenser is not mounted in a circular clamp. Instead, it is fitted with a circular dovetail ring that slides into the condenser mounting guide.

This mounting interface is used on, among others, the following microscope models:
- Zeiss Standard 14 / 16 / 18 / GFL
- Zeiss Standard WL / WL 89
- Zeiss Standard 20 / 25 / 25 ICS
- Zeiss Universal
- Zeiss Photomicroscope I / II / III RS
- Zeiss Ultraphot

The ring has a diameter of 41.3 mm and three mounting holes used to attach it to the condenser. It also features a tapered recess that engages with the locating pin in the condenser holder, ensuring correct positioning of the condenser.

When attached to a condenser made by another manufacturer, this ring makes it possible to use, for example, the PZO KPI-2 DIC condenser and dozens of other condensers on Zeiss Standard-class microscopes.

Note regarding the mounting diameter: during nearly 50 years of production of this microscope series, the dovetail diameter was always approximately 42 mm, but it was never exactly identical. Depending on the production year, the material (plastic, aluminium or brass), and the condenser type (classic Abbe condenser or phase contrast disc condenser), the actual diameter may range from just over 41 mm to almost 43 mm. This relatively large tolerance is a consequence of the condenser holder design. The holder incorporates spring loading, a locating pin and centring/locking screws. As a result, condensers fitted with a mounting ring between approximately 41 mm and 43 mm in diameter can almost always be mounted securely and remain well centred.

microscope base. It transfers the light beam from the illuminator, homogenises it (the image of the filament is diffused by means of a diffuser), and then properly collimates it using a collimating lens. The prepared light beam is then directed to the deflecting mirror (this is a separate microscope component).

This is part of the transmitted-light optical path. The diffuser (frosted ground glass) and the collimating lens are housed inside a metal enclosure that serves as a heat sink for the halogen lamp. The complete assembly forms the illuminator housing.

This particular collector with frosted ground glass was removed from a Carl Zeiss Photomicroscope (also known as Zeiss PM / Zeiss Phomi).
It fits the following microscopes (this is not a complete list):
- Zeiss Photomicroscope (Zeiss PM / Phomi)
- Zeiss Photomicroscope II (Zeiss PM2 / Phomi II)
- Zeiss Photomicroscope III RS (Zeiss PM3 RS / Phomi III)
- Zeiss Universal
- Zeiss Ultraphot
- most likely also Zeiss Standard 16 / 18 / WL / WL 89 / GFL microscopes

VERY IMPORTANT: This component is intended for the 6V 15W incandescent illuminator. Zeiss microscopes may be equipped either with a 6V 15W incandescent illuminator (a tubular illuminator inserted into the microscope base) or with an external halogen Lampenhaus mounted to the rear of the microscope base. Microscope versions equipped with a halogen illuminator use a different illuminator holder than the one presented here.

Other names used for this component:
- illuminator holder with frosted filter
- illuminator tube
- illuminator holder with frosted ground glass
- sometimes the foreign-language term "Lampenhaus" is also used, although it is not a precise name for this component

Basic parameters of this phase annulus:
Manufacturer: Carl Zeiss (Oberkochen, West Germany)
Condenser marking: "2"
For objectives: marked "Ph2", i.e. magnifications from 16x to 40x
Material: glass mounted in a metal retaining ring with flange
Outside diameter of the retaining ring: 22 mm
Phase annulus glass diameter: 16 mm
Height of the retaining ring: 3.5 mm

Important: this microscope component (phase annulus / phase diaphragm) is not intended for any specific microscope model. It is a component used to upgrade or repair a microscope phase contrast condenser. It is not intended for upgrading or repairing one specific condenser model. Many Carl Zeiss condenser models have a suitable opening into which this phase annulus can be inserted.

This particular phase annulus was removed from a fluorescence phase contrast condenser - an older version of the Zeiss condenser P/N 46 52 78. Before installing it in your condenser, carefully compare the shape of its housing and the dimensions of the retaining ring.

Material: glass mounted in a metal retaining ring with flange
Outside diameter of the retaining ring: 22 mm
Diameter of the clear glass disc: 16 mm
Height of the retaining ring: 3.5 mm

Below are some example applications for this clear glass blank. It can be printed or fitted with, among others:
- a phase annulus or darkfield annulus matching the original one that was installed in the condenser but has become damaged
- an annulus missing from the condenser
- coloured Rheinberg rings
- oblique illumination diaphragms producing a DIC-like effect
- a Hoffmann modulation contrast pattern
- phase annuli for objectives made by other manufacturers, for example Carl Zeiss Jena PhV
- any completely custom DIY design

This particular clear glass ring insert was removed from a fluorescence phase contrast condenser - an older version of the Zeiss condenser P/N 46 52 78. Before installing it in your condenser, carefully compare the shape of its housing and the dimensions of the retaining ring.

Interchangeable diaphragm carriers (whether for phase contrast or, for example, darkfield) make it possible to configure a phase contrast condenser exactly as required. This allows the condenser to support precisely the observation techniques and microscope objectives needed.

The clear glass blank presented here is not a component intended for any specific microscope model. Instead, it is used to upgrade or repair a microscope phase contrast condenser. Likewise, it is not dedicated to any specific condenser model. Many Carl Zeiss condenser models have a suitable opening into which this complete insert can be fitted and customised with your own pattern.

applications.

Replaceable diaphragms (both for phase contrast and darkfield) for phase contrast condensers allow the condenser to be configured individually. Thanks to this, it can support exactly the observation techniques and exactly the microscope objectives that are required.

Important: by installing the fluorescence-polarization diaphragm presented here, a condenser currently equipped with standard phase contrast diaphragms can be upgraded with this unique function. A detailed description of the capabilities offered by this technique is provided below.

Basic parameters of this phase contrast diaphragm:
Manufacturer: Carl Zeiss (Oberkochen, West Germany)
Condenser marking: "2". On the Zeiss condenser P/N 46 52 78 this position is marked in blue
For microscope objectives: to obtain phase contrast operation, use microscope objectives marked "Ph2", i.e. objectives with magnifications from 16x to 40x
Substrate material: glass mounted in a metal holder with a flange
Ring material: polarizing film
Outside diameter of the retaining ring: 22 mm
Glass disc diameter: 16 mm
Retaining ring height: 3.5 mm

Important: this component (phase contrast annulus / phase contrast diaphragm) is not intended for a specific microscope model. It is a component for upgrading or repairing a microscope phase contrast condenser. It is not intended for upgrading or repairing any specific condenser model. Many Carl Zeiss condenser models have a matching opening into which this phase contrast annulus can be installed.

In the Carl Zeiss condenser P/N 46 52 78, the phase annuli in positions 2 and 3 are not ordinary openings in an opaque mask but openings in a polarizing film. The polarization direction of these annuli is N-S, so the direct light beam that forms the phase contrast image is linearly polarized. Since it is polarized, its intensity can be adjusted continuously with a second polarizer - without any mechanical parts, diaphragms or shutters.

This second polarizer can be any pair of rotatable polarizing filters. In the original Zeiss design, this is the Carl Zeiss light control unit P/N 47 72 20 with two independently rotatable polarizers mounted beneath the condenser. This makes it possible to switch on phase contrast while simultaneously reducing the illumination intensity to a safe level.

- when the polarizer is aligned parallel to the N-S axis of the annulus - full transmission, maximum phase contrast beam, full-strength phase contrast image;
- when the polarizer is crossed (E-W) - the annulus "goes dark", the objective phase plate no longer receives the direct beam, and the phase contrast image disappears;
- when the polarizer is set to intermediate positions - smooth adjustment of the contribution of the phase contrast image.

When the illumination source is a fluorescence lamp (or, of course, an LED FL light source), simply rotating the polarizer beneath the condenser (together with removing the excitation filter) allows the user to switch from a fluorescence image to a conventional phase contrast image. With the polarizer crossed and the excitation filter installed, the phase annulus is extinguished and only pure fluorescence is visible; as the polarizer is rotated, the phase contrast image gradually increases and is superimposed on the fluorescence image. The second polarizer in unit P/N 47 72 20 is additionally used to attenuate the overall illumination intensity (to protect the specimen or to control the specimen's exposure to fluorescence light).

And now an interesting note from the Ultraphot-shop website https://www.microscopeparts.eu/(http://www.the-ultraphot-shop.org.uk/bicolor.htm), © Spike Walker 2007:

Because the annulus is a linear N-S polarizer, it can be used to produce coloured phase contrast: when a two-colour polarizing filter (Cokin type) is placed between the microscope polarizer and the condenser annulus, the specimen takes on the colour of the illuminating annulus against the background colour of the remaining part of the disc - for example, an orange specimen on a green background when using a red-green filter.

This particular phase contrast annulus was removed from a fluorescence phase contrast condenser - an older version of the Zeiss condenser P/N 46 52 78. Before deciding to install it in your condenser, carefully compare the shape of its housing and the dimensions of the retaining ring.
