Description of this part for the microscope.

tube
Stand mount: 41 mm dovetail
Head mount: 41 mm dovetail
Inherent magnification: none (1.0x)

Interestingly, the head has a slot for slide inserts (e.g., color, fluorescence, or polarizing filters).

Because IOR produced microscopes modeled after the Carl Zeiss Jena and Lomo, many (most) IOR parts are compatible with microscopes from these manufacturers.

Application: Zeiss Axio microscopes, second series
Manufacturer number: 425503-9901-000
Light split: 0/100 and 100/0

This trinocular photo tube contains a Zeiss infinity correction tube lens 425308-0000-000.

Parameters of the Zeiss 425308 lens:
Lens type: correction lens (en: infinity corrected tube lens)
Magnification: none (i.e. 1x)
Wavelength range: 380 - 700 nm
Diameter: 40 mm
Length: 12.8 mm
Thread: M36 x 0.75

The Zeiss tube lens 425308-0000-000 is required to use infinity-corrected Zeiss microscope objectives on microscopes from other manufacturers - including those designed for 160 mm tube length. It is also very often used in super macro photography to connect infinity-corrected objectives to a camera.

This element can be a solution to the following issues:
- How to repair or replace the prism in the Zeiss 425503 photo tube?
- What to do in case of prism delamination in the Zeiss 425503 head?
- Repair of a mechanically damaged Zeiss 425503 trinocular tube
- What to do if the Zeiss "tube lens" 425308 is damaged, scratched, or of poor quality?
- Can Zeiss objectives be used on microscopes from other manufacturers?
- Can infinity-corrected objectives be used on a 160 mm microscope?
- How to take super macro photos using infinity-corrected microscope objectives?

And once again at the end: carefully look at the photos. Note that this trinocular (photo tube) does not include a binocular eyepiece head.

This element provides an ergonomic, inclined positioning of the head relative to the user's eyes.

The element with manufacturer part number 452907 consists of two main parts:
- angle tube
- binocular head (also referred to as binocular).
Here, only the angle tube is shown and offered, without the binocular head.

Basic parameters:
- mounting to microscope stand: 57 mm dovetail
- mounting of the head to the angle tube: three screws

Important: other Zeiss binocular models can also be mounted on this angle tube, not only the one originally installed in the Zeiss P/N 452907 head.

for taking microscope photographs or recording microscope videos. This is a gray photographic adapter.

Basic technical parameters:
- mounting connection to microscope stand: 41 mm dovetail
- output connection type on the photo port: 49 mm internal thread
- connection for binocular head mounting: Jena standard 41 mm dovetail
- magnification directed to the binocular head: 1.6x
- magnification on the photo output: none (that is 1.0x)

Because this photo head has a 49 mm threaded output, virtually any device, camera, adapter, tube or other accessory can be connected after using an appropriate 49 mm thread adapter. Direct projection technique may be used (because there is no additional optics inside), or any projection eyepieces may be installed in the optical path.

This photographic attachment is intended mainly (but not exclusively) for the following microscope models:
- Carl Zeiss Jena Eduval
- Carl Zeiss Jena Laboval
- Carl Zeiss Jena Ergaval
- Carl Zeiss Jena Amplival
- Carl Zeiss Jena Vertival
- Carl Zeiss Jena Epival
- Carl Zeiss Jena Metaval
- Carl Zeiss Jena Telaval
- Carl Zeiss Jena Pictoval
- Carl Zeiss Jena Epignost

The list above contains Mikroval series microscopes with gray housings - just like the tube shown and offered here. However, it also works with older black Carl Zeiss Jena microscopes:
- Carl Zeiss Jena L-Stativ (models Lg, Lu and Lr)
- Carl Zeiss Jena Lumipan
- Carl Zeiss Jena Ng
- Carl Zeiss Jena Nf (and NfPk)

Please note that microscopes from other manufacturers also use the 41 / 41.5 mm dovetail connection standard. Because of this, this photographic head can also be used with microscopes made by:
- Lomo (for example Lomo Biolam)
- Meopta
- IOR
- selected Reichert microscopes (for example Reichert Neozet)
- Will Wetzlar
- Hund Wetzlar
- Leitz Wetzlar

This Carl Zeiss Jena tube is also very often used with microscopes having a larger head mounting diameter. In such cases users apply additional spacer or thickening rings. Because of this, this photo adapter also fits microscopes from manufacturers such as:
- PZO (for example the PZO Biolar model with 43 mm connection)
- Olympus (for example the Olympus CH model with 42 mm connection)

The element that allows a photographic camera or imaging camera to be connected to Carl Zeiss Jena Mikroval series microscopes may be referred to by different names. Commonly used names include:
- trino head
- trinocular head
- photo head
- photographic head
- photo attachment
- photographic attachment
- photo adapter
- photographic adapter
- photo tube
- photographic tube
- phototube
- photographic angle tube
- and various combinations of the words head, attachment, adapter or tube with terms such as photo, photographic, for camera and similar

Carl Zeiss Jena, PZO, Meopta, Olympus, IOR and others.

This tube makes it possible to connect a camera or photographic camera to a trinocular head or directly to the microscope body, even when no trinocular head is installed.

Originally, this adapter was designed for the Lomo TRN-1 trinocular head. This head was used in Lomo Polam polarizing microscopes from the early 1970s onwards.

Several remarks regarding the model designation of the trinocular head for which this component was originally intended:
- the name Lomo TRN-1 is the Latin alphabet designation. In Cyrillic script the model designation appears as TPH (for example model TPH1Y4.2), and this designation is used in the manual for the Lomo Polam L-211 microscope
- the vast majority of these trinocular heads are not marked with any model designation
- the Envirotools website http://www.envirotools.hu/ateso_fenyu_polarizacios_mikroszkop.htm refers to this trinocular head as HU-POL

In the last photograph, an arrow indicates exactly which component is being offered and where it is located in the Lomo Polam microscope, allowing this part to be identified unambiguously.

Basic technical parameters of this tube:
Mounting method to the trinocular head or microscope: 41 mm dovetail mount (this is also the Carl Zeiss Jena standard)
Camera mounting method: male M39 thread
Alternative camera mounting method: since the M39 thread can be removed, a plain smooth tube with a diameter of 35 mm remains
Additional optics: yes, the original optics are installed inside, although they can be removed, leaving only an "empty tube".

This is not "a tube dedicated to a specific microscope model". It is a tube originally mounted on the third port (photo port) of a trinocular head. Since a trinocular head can be installed on microscopes other than the model with which it was originally supplied, this tube can be regarded as a universal accessory.

These technical parameters make it possible to use this tube with virtually any microscope manufactured by:
- Lomo (for example Biolam, Polam, MBB-1A and others)
- Carl Zeiss Jena (for example Ergaval, Amplival, Jenamed and others)
- IOR, Meopta and other manufacturers using a 41 / 41.5 mm dovetail mount

In addition, a 41 mm dovetail tube can easily be mounted on microscopes equipped with a 42 mm or 43 mm opening, for example:
- Olympus (for example CH, CH-2, BH-2 models)
- PZO (for example Biolar, Studar, MB-30 and others)

The entire list of microscope manufacturers and models given above may also be treated as a list of microscopes compatible with the Lomo TRN-1 trinocular head. Indeed, many examples can be found on the Internet showing this head being used with microscopes made by manufacturers other than Lomo.

Because this tube is equipped with an M39 thread by default, almost any camera or photographic camera can be attached by means of a suitable adapter, for example:
- devices with M42 threads
- devices with C-mount threads
- Nikon, Sony, Olympus and other camera standards

This is therefore a universal photo tube featuring a 41 mm dovetail on one side and either an M39 thread or a 35 mm tube on the other side.

In the image gallery, every photograph includes a millimetre scale, and in addition, the dimensions of the dovetail, tube and thread have been measured with calipers so that compatibility can be determined precisely.

(Phomi) microscopes.

This is an intermediate tube forming the main optical module of the microscope. It is mounted onto the microscope arm, and the binocular head is then attached to this intermediate tube. The module integrates the following components:
- a third optical path (photo output), which is why this module is sometimes referred to as a trinocular tube
- an Optovar magnification changer with a Bertrand lens
- a dovetail mount for the objective revolver
- a large insert for a round filter and slots for additional inserts

This intermediate tube is compatible with the following microscopes:
- Zeiss Universal (Carl Zeiss Standard Universal)
- Zeiss Photomicroscope (Zeiss Phomi)

The Optovar magnification changer integrated into this intermediate tube features a rotating turret with the following positions:
- PH (Bertrand lens)
- 1.25×
- 1.6×
- 2×

The complexity of this design makes the module susceptible to damage of individual internal components, especially the optical elements (prisms and lenses).
