# Belongs to category:
Illuminators

# Description and specifications:
Lamphouse for the Meopta DRU-3 microscope.

This unit contains an iris diaphragm (field diaphragm), allowing the illumination to be set according to Köhler standards.

The device consists of:
- a slot for mounting the illuminator
- the iris diaphragm
- an angled mirror
- a place to insert 32 mm diameter filters

Note - the set does NOT include an illuminator or bulb, so there is no light source. This is only the "housing".

# Examples of use
- if you own a Meopta microscope and want to use this lamphouse
- if you want to use this component for a microscope from another manufacturer
- as a service part for replacement, if you have a complete illuminator that is damaged (e.g., broken iris diaphragm, oxidized reflective layer on the mirror, or cracked protective glass) or of very poor quality
- if you want the original lamphouse to make your own illuminator, e.g., with an LED bulb
