# Description and specifications:
Complete coarse focus and fine focus assembly with internal shaft and pinion for the Leica DMRB microscope and other microscopes from the Leica DM-R series.

The Leica DMR series includes many microscope models. This focus assembly is compatible with, among others:
- Leica DMRB (biological model)
- Leica DMRM (materials science model)
- Leica DMRD (for photomicrography)
- Leica DMRP (polarizing model)

This complete assembly consists of:
- two fine focus knobs, one on each side of the microscope
- two coarse focus knobs, one on each side of the microscope
- a shaft connecting the focus controls on both sides
- the shaft carries a pinion
- the shaft and pinion are mounted in a brass sleeve

The complete assembly can be disassembled into its individual components (knobs, screws, washers, shaft and other parts). To install it in the microscope (for example during servicing or when replacing a damaged component), the assembly must first be taken apart.

# Examples of use
- use this assembly as a replacement if any individual component of this assembly has been damaged in your Leica DMR microscope

# Removed from microscope:
Leica DMRB

# Also compatible with the following microscopes:
- Leica DMRB
- Leica DMR
- Leica DMRM
- Leica DMRD
- Leica DMRP
