Description of this part for the microscope.

08 160/-
Color correction: Planachromat
Numerical aperture: 0.08
Tube length: 160 mm
Focal length: 45 mm
Cover glass: no
Immersion: no
Thread: RMS

This lens provides an excellent, wide image, and because it doesn't require a cover glass, it's often used for macro photography and stacking.

Important - this lens is not suitable for taking photos using the "direct-projection" technique, as it requires plan-compensation optics.

A microscope objective with such low magnification is used, among others, in the following fields:
- tissue overview examination in pathomorphology
- observation of insects
- observation of minerals
- observation of inclusions in amber
- handwriting analysis
- observation of micromollusks
- and many others

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.

This particular plunger pin was part of a screw removed from a Zeiss Standard WL microscope, but it will most likely fit most models of the Standard series, for example:
- Zeiss Standard 14 / 16 / 18
- Zeiss Standard WL / WL 89
- Zeiss Standard GFL
- Zeiss Standard Universal
- Zeiss Standard Photomicroscope
- Zeiss Ultraphot

Here you can see a complete screw of this type: https://www.microscopeparts.eu/part/99484 - this is the type of screw that contains this pin inside. In the last photos in the gallery, you can also see the complete arm of a Carl Zeiss Standard WL microscope, with an arrow indicating which element this is and where it is located in the microscope.

Note - over the years, Zeiss microscopes (or the same microscopes sold under the names Zeiss-Winkel or under the Opton brand), especially simpler models such as the Zeiss Standard Junior, may have used different screws for attaching microscope heads. They were not necessarily spring-loaded screws - sometimes ordinary threaded clamping screws were used.

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

microscopes, a module is screwed to the end of the microscope arm. This module also serves as the head carrier and may have rails for mounting a removable nosepiece housing, or sometimes an integrated nosepiece.

Here I present and offer the Allen screw used to attach this particular module to the microscope arm.

In the last photos in the gallery (https://www.microscopeparts.eu/gallery/91033), you can see the microscope arm of a Zeiss Standard WL 89, with an arrow indicating which screw this is and where it is located in the microscope. This allows for unambiguous identification of this component.

An example of a module from a Zeiss Standard 14 microscope with an integrated nosepiece can be seen here: https://www.microscopeparts.eu/photo/99489-5 - this screw also fits this module.

Please note that Carl Zeiss Standard GFL microscopes use a different screw. This is immediately apparent because it is not an Allen screw - you can see it here: https://www.microscopeparts.eu/photo/99667-8

IMPORTANT: This is not the screw used to mount the microscope head to the stand (more precisely, to the head carrier). Here: https://www.microscopeparts.eu/gallery/99484 you can see a gallery of photos of the screw used to mount the head to the microscope. The screw presented here is NOT that screw.

Note - over the years, Zeiss microscopes (or the same microscopes sold under the names Zeiss-Winkel or under the Opton brand) may have used different screws to mount the head carrier to the stand arm. Before deciding to replace a screw in a microscope, it is best to carefully compare its appearance and dimensions with the photos in the gallery or ask a question on the forum https://mikroskopie-forum.at/forum/

objective:
Manufacturer: Zeiss West Germany
Engraving on the objective: Planapo 63/1,4 Oel 160/-
Manufacturer catalogue number: 46 18 40 - 9901 (also written as 461840-9901)
Magnification: 63x
Numerical aperture (N.A.): 1.4
Optical correction: plan-apochromatic
Immersion: yes, oil
Coverslip: according to the engraving on the barrel of this objective, it can be used both without a coverslip and with a standard coverslip of 0.17 mm thickness
Tube length: 160 mm
Parfocal distance: 45 mm
Thread: RMS
Specimen protection: yes, the objective has a spring-loaded mechanism preventing the slide with the specimen from being broken
Phase contrast: no - the objective has no phase rings inside
DIC: prisms allowing work in DIC mode are available on the market for this objective (sold separately)

This objective fits practically any microscope of any manufacturer, provided it has an RMS thread and accepts objectives for a 160 mm tube length with a parfocal distance of 33, 37 or 45 mm. A few such microscopes are listed as examples in the "compatibility" section, but this is not a complete list.
