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:
Focusing blocks

# Description and specifications:
Service part (repair element) for Olympus BX microscopes. This is a focusing block with gears for coarse and fine focus movement.

This is a part removed from the stand of an Olympus BX40 microscope. It has been tested and cleaned - and is suitable for use as a service element for repairing a damaged microscope. Many smaller Olympus service elements do not have their own catalog numbers or commercial names, therefore in the last photos in the gallery I indicate with an arrow exactly which element is being offered and where it is located inside the microscope. In this description some names used are descriptive rather than official technical commercial names.

Olympus BX series microscopes use identical assemblies in many different models, therefore there is a high probability that this element - although removed from a BX40 model - is also compatible with other BX series models (for example BX41, BX43, BX50, BX51 etc.). However, before deciding to install such an element in an Olympus BX microscope, it is advisable to first carefully compare shapes and dimensions or ask appropriate questions on forums and in Olympus BX microscope user groups.

Other names are also used for this component:
- focusing mechanism
- coarse and fine focus mechanism

- gear block
- focus block
