PZO Biolar field diaphragm and light collector lens - main photo

This is description of this part:

The illumination module block in the microscope base (known as the "tube").

The complete illumination system in the PZO Biolar microscope base (in any version) consists of:
- an illuminator (light source)
- a "tube" containing collimating lenses and a field diaphragm
- a 90-degree angle mirror
- a light filter (clear or blue)

This offers an integrated block, also known as a "tube." It consists of:
- a metal tube with holes that acts as a heat sink, dissipating heat from the light source
- a set of lenses that collimate the illumination beam
- a field diaphragm (iris diaphragm)
- a knob that opens/closes the diaphragm

This element is the same for all lighting types, regardless of whether it's a 6V 15W bulb, a PZO OH1 (12V 100W) or a modified LED, so it fits any version of the PZO Biolar microscope:
- B
- B2
- GF
- Pol
- DIC
- EPI
- Fluoreszenz

It contains two critical components: a collimating lens that often cracks under temperature, and a field diaphragm whose blades are prone to bending.
