Leica
Head model: 11505193

The angled tube (German: Winkeltubus) is the component visible in the last photos in the gallery. This component is mounted to the microscope stand, and the binocular head is screwed onto it at an ergonomic angle.

On this page, I offer the interior of this angled tube.
- metal internal structure
- mirror angled prism
- lower lens (as far as I know, this is a focal lens, also known as a "tube lens" for infinity correction).

If I'm correct that this lower element is a "tube lens," then it's a sought-after component:
- by macro photographers to use infinity lenses
- by people wanting to convert their 160mm/170mm microscope to be compatible with infinity-corrected lenses.

This prism is mounted on a metal base which is screwed into the head under the eyepiece tube. This metal base allows adjustment of the prism in order to achieve perfect image collimation, meaning that the images for the left and right eye are aligned.

but it is very likely also compatible with the identical, but non-motorized (manual) head number 11505146.

For the motorized movement system in the Leica 11505145 head, this prism is mounted on a carriage which may differ from the one moving the prism in the manual version of this head (11505146). To use this prism in the trinocular head 11505146, it must be removed (prism only) and re-glued into a new position.

Leica photo-trinocular heads, numbers 11505145 and 11505146 are compatible with microscopes:
- Leica DM4000
- Leica DM4500
- Leica DM5000
- Leica DM6000
- and likely others

Note - the prism shown here has a minor chip on a corner outside the optical path. It does not affect operation and is not visible in the wide field of view.

This service part may solve the following issues with Leica trinocular heads 11505145 and 11505146:
- how to remove fungus from a prism?
- can delamination in a Leica head prism be removed?
- can a mirror inside the prism be repaired if it has oxidized?
- cracked prism in a microscope head

component will also fit the photographic trinocular head of the following macroscope models:
- Wild M400
- Wild M450 (another name: Leica M450)

This service component may solve the following problems with the trinocular head of the Wild Heerbrugg / Leica M450 macroscope:
- how to remove fungus from the prism?
- can delamination on the prism of the Wild M420 head be removed?
- is it possible to repair the mirror in the prism if it has oxidized?
- cracked prism in the head of the Leica M420 macroscope

The macroscope is an advanced stereoscopic microscope with a high-resolution ZOOM objective.

Why are dual names Wild and Leica used? The M400 macroscope was manufactured by Wild Heerbrugg (Switzerland). Later, the Wild company was acquired by Leica and the M420 and M450 models may be labeled either Wild M420 / Wild M450 or Leica M420 / Leica M450. Note: this is different for the Wild M400 model - it does not have a Leica equivalent, because "Leica M400" is a model of a surgical microscope.

The last photo in the gallery shows a disassembled Leitz Wetzlar 512582 binocular head, with an arrow pointing to the prism in question and to its position inside the head. This makes the part easy to identify.

Replacing this prism in a Leitz Wetzlar microscope head can be the remedy for the following problems:
- if the prism in your head is mechanically damaged: it may be cracked or chipped
- if the prism to be replaced has a damaged anti-reflective coating: this may be caused by fungus, or the coating may be scratched by improper cleaning
- if discolouration or separation (delamination) is visible inside the prism. This is a cemented prism, and over the years the cement can discolour or come apart in places, which is unfortunately visible in the field of view while working with the microscope
- if the reflective layer inside the prism (usually silver) oxidises and loses its properties in places or completely

Before you decide to use this prism in a Leitz Wetzlar head other than model 512582, first compare the exact dimensions (a millimetre scale is visible in the photos) and, if in doubt, ask on internet groups and forums.

The irreplaceable Carl Hunsinger has written an excellent service manual for this microscope head: https://www.alanwood.net/downloads/olympus-bh2-bi30-binocular-head-repair.pdf.

This prism is not a spare part for the microscope itself. It is a repair part for the Olympus BH2-BI30 microscope head - and that head can sit on various microscopes, even on instruments from manufacturers other than Olympus. The most important microscopes this head is most often used with are listed in the "compatibility" section, but this is by no means a complete list.

Description of this part for the microscope.

The metal casting - the one with the eyepiece tube that the prism holder is attached to - carries the number AB0303.

This particular prism was removed from an Olympus BH2-BI30 binocular head, but it should also fit, among others, the following microscope heads with eyepiece tubes for eyepieces of 23.2 mm diameter:
- Olympus BH2-BI30
- Olympus BH2-TR30
- Olympus BH2-TBI
- Olympus BH2-TTR
- Olympus BH2-TET

Before you decide to use it to repair a head other than the one it was removed from, I recommend checking it first with specialists on forums or groups devoted to Olympus microscopes.

The prism shown here sits in its original holder, and the whole assembly is attached to the left eyepiece tube (casting AB0303) - and that is exactly what I am offering, as a complete unit.

Description of this part for the microscope.

tube. The metal casting - the one with the eyepiece tube that the prism holder is attached to - carries the number AB0304.

This particular prism was removed from an Olympus BH2-BI30 binocular head, but it should also fit, among others, the following microscope heads with eyepiece tubes for eyepieces of 23.2 mm diameter:
- Olympus BH2-BI30
- Olympus BH2-TR30
- Olympus BH2-TBI
- Olympus BH2-TTR
- Olympus BH2-TET

Before you decide to use it to repair a head other than the one it was removed from, I recommend checking it first with specialists on forums or groups devoted to Olympus microscopes.

The prism shown here sits in its original holder, and the whole assembly is attached to the right eyepiece tube (casting AB0304) - and that is exactly what I am offering, as a complete unit.

This prism is not a spare part for the microscope itself. It is a repair part for an Olympus microscope head - and that head can sit on various microscopes, even on instruments from manufacturers other than Olympus. The most important microscopes this head is most often used with are listed in the "compatibility" section, but this is by no means a complete list.

The irreplaceable Carl Hunsinger has written an excellent service manual for the BH2-BI30 microscope head (https://www.alanwood.net/downloads/olympus-bh2-bi30-binocular-head-repair.pdf) and for the BH2-TR30 (https://www.alanwood.net/downloads/olympus-bh2-tr30-trinocular-head-repair-manual.pdf).

Here are the microscope models in which the heads this prism fits are most often used:
- Olympus BH-2 BHS
- Olympus BH-2 BHT
- Olympus BH-2 BHTU
- Olympus IMT-2

A note on the eyepiece tube diameter: the mounting diameter for the eyepieces is 23.2 mm, but some sources state 23 mm or 23.5 mm - that is a rounded measurement, and it is still one and the same tube.
