This is description of this part:
20x microscope objective made by Lomo with the LZOS Lytkarino factory logo and a unique "golden" serial number.
Manufacturer: LZOS Lytkarino (commonly, although incorrectly, referred to as "Lomo")
Model: 20 0,40
Magnification: 20x
Correction: Achromat
Numerical aperture: 0.40
Tube length: 160 mm
Focal length: 33 mm
Cover glass: 0.17 mm
Immersion: no
Thread: RMS
Serial number: 01234
It can be used with any microscope from any manufacturer. Of course, the microscope must be compatible, i.e. support RMS objectives, TL=160 mm and FL=33 mm.
After installing a 12 mm adapter, this combination of adapter and objective will function as an objective with FL=45 mm.
This objective is attractive mainly to collectors because:
- there are very few microscope objectives with the LZOS logo on the secondary market
- the objective has a so-called "golden serial number": 01234
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
