Objective

# Description and specifications:
Lomo microscope objective for EPI reflected and incident light - for work without a cover slip.

Excellent external condition and perfect optical condition. It is not easy to find a used objective in this condition.

Manufacturer: Lomo
Magnification: 40x
Model: D=0 40 0.65
Numerical aperture: 0.65
Tube length: 160 mm
Focal length: 33 mm
Cover slip: no
Thread: RMS + adapter to M27 thread
Marking: "D=0" = work without cover slip

This is an objective for working with reflected light (but also transmitted light) without a cover slip.

Objective with RMS thread, but can be screwed into an adapter for M27 thread, allowing use in a microscope, e.g., Biolam-M. Of course, the objective can be unscrewed and another objective can be screwed into the adapter.

Info: M27 thread is also a standard used by Zeiss Axio microscopes. Therefore:
- this objective can be used in Axio microscopes with M27 thread
- this adapter can be used in Axio microscopes with another objective

This adapter is not a 3D-printed plastic part - it is a professional, metal, original product by Lomo.

# Examples of use
- If you have a microscope with EPI reflected light and you are missing an objective with this magnification
- If you need a 40x objective for work without a cover glass for your microscope (for example a biological one)
- If you want to use RMS-M27 adapters for your own objectives
