# Part manufacturer:
Olympus

# Full manufacturer name:
Olympus Corporation Tokyo Japan

# Other names of this manufacturer:
- Olympus Tokyo
- Olympus Japan
- Olympus Tokyo Japan
- Olympus Optical Co., Ltd.
- Olympus Corporation.
These are names commonly used to refer to this manufacturer of microscopes and microscope parts, even if they are not official. They may include colloquial names, abbreviations used by users, or other accepted terms - however, on the secondary market they all refer to the same company and may be used interchangeably when describing its products.

# Belongs to category:
Sliders

# Description and specifications:
Set of two polarizing sliders for microscopes: the Olympus BH2-NAN-2 slider with a rotatable polarizing analyzer and a rotatable polarizer for Olympus BH-2 microscopes with a reflected light illuminator.

Olympus BH2-NAN-2 analyzer slider:
Slider type: rotatable polarizing analyzer
Rotation: the analyzer rotates within a range of 0-45 degrees
Marking on the slider: Olympus BH2-NAN-2
Model in the manufacturer catalog: BH2NAN2
Dimensions: width 45 mm, thickness: 7.5 mm, overall length: 68.5 mm, length of the inserted part: 48.5 mm
Intended use: for the EPI reflected light illuminator

Olympus polarizer slider:
Slider type: rotatable polarizer
Rotation: the polarizer rotates within a range of 0-360 degrees
Marking on the slider: none
Model in the manufacturer catalog: unknown
Empty position: yes - the polarizer has two positions, one with the polarizing filter and the other empty
Dimensions: width 45 mm, thickness: 6 mm, overall length: 85 mm
Intended use: for the EPI reflected light illuminator
Notes: the absence of any marking on the slider suggests that it is not a pull-out slider, but is permanently mounted in the EPI reflected light illuminator - it can, however, be moved between the empty position and the polarizer position

If you want to use this slider in a different microscope - check the shape and the exact dimensions shown in the photos.

Please note - the commonly used terminology is slightly disordered, and foreign as well as incorrect names are often used. The most common mistake is that the analyzer is called a polarizer - and unfortunately this mistake is so frequent that it has to be taken into account. Here are examples of the names in use:
- polaryzator
- polarisator
- polarizer
- polariser
- filtr polaryzacyjny
- filtr POL
- circular polariser
- CPL Filter
- POL filter
- polarisations Filter
- polarization Filter
- analizator
- analisator
- Analysator
- POL analizer
- polarization analyser

Unfortunately, I do not know the model of the EPI reflected light illuminator these sliders fit. Fortunately, Mr Thomas Woitzik has photos of an Olympus BH2 BHS microscope with exactly this EPI equipment on the pages of his excellent online shop: https://www.mikroskop-online.de/mikroskope/verkauf/gebrauchte-mikroskope/auflichtmikroskope/olympus-bh2-mit-auflicht-hellfeld-auflichtpolarisation-photoausgang-und-durchlichtmoeglichkeit/

# Examples of use
- if you have a compatible microscope with a reflected light EPI illuminator, but you are missing the Olympus BH2-NAN-2 slider or the rotatable polarizer
- if you have such a rotatable analyzer, but it is damaged or in very poor condition
- if you have such a rotatable polarizer, but it is damaged or in very poor condition
- if you want to use this slider in a different microscope
- if you need a good quality rotatable polarizer / analyzer for your own DIY project involving observation in polarized light
