This is a rare, professional microscope objective with a very wide range of applications. Main features that make this objective exceptional:
- Water immersion is preferred by many users over oil immersion
- Very high numerical aperture (up to 0.90) provides high-resolution images
- Built-in iris diaphragm allows adjustment of the aperture
Despite the "L" marking, the objective can of course also be used with standard illumination.
LOMO objectives with the "L" luminescence marking differ from those without this symbol by:
- Improved transmission in the UV and blue spectral range
- Lower glass autofluorescence
- No or strongly reduced use of organic adhesives
