# Belongs to category:
Revolvers (turrets)

# Description and specifications:
4-position turret for the Olympus BHM metallurgical microscope. The turret is interchangeable and mounts on a dovetail. It has a reflector inside for use with EPI darkfield objectives.

Number of ports: 4
Objective thread: M25
Objective type: Olympus NEO
Mounting method: Dovetail

I've also used the Olympus BHM microscope with Carl Zeiss Jena M25 thread objectives (Jenaval microscope objectives), and they fit and work very well :-)

I'm almost certain (but I haven't checked) that this turret fits the Olympus BH model (but not the BH-2), which has a turret for RMS objectives by default. However, it can be swapped out and work with an M25 objective :)

# Examples of use
- if you have a microscope without a turret
- if your turret is damaged
- if you want to have more than one turret to quickly switch between entire sets of objectives
- if you have an Olympus BH microscope and want to work with M25 lenses
