This is description of this part:
40x microscope objective manufactured by Wild Heerbrugg for the Wild M20 microscope.

Model: 40/0.65 d=0.17
Magnification: 40x

Numerical aperture: 0.65
Tube length: 160 mm
Focal length: 33 mm
Cover glass: yes, 0.17 mm thickness

Thread: RMS
It can be used with any microscope from any manufacturer. Of course, the microscope must be compatible, meaning it must support RMS objectives with TL=160 mm and FL=33 mm. After installing a 12 mm adapter, this objective can of course also be used in microscopes designed for FL=45 mm.
The fact that this objective has FL = 33 mm (meaning it is a so-called short objective) allows it to be used with microscopes from other manufacturers, including:
- Carl Zeiss Jena Lg
- Carl Zeiss Jena Lumipan
- Lomo Biolam
- Lomo MBB-1A
- PZO MB-10
- Nikon S
- Olympus KHC
What is this part needed for?
- If you have a microscope without objectives and need to restock it using original parts
- If you have a microscope that doesn't have an objective lens with this magnification and want to restock it
- If you have such an objective lens, but it's of very poor quality or damaged
- If you're cautious and want to have a spare objective lens
