Achromatic microscopic lens with 45x magnification. Standard thread 20 mm, commonly found in laboratory microscopes, incl. Bresser (Researcher, Analyth), Delta Optical (selected models), TPL and many others. Fold 45 is very rare (a typical, widely distributed multiplicity is 40x), which is searched for in order to obtain specific, expected magnification in the microscope. • construction: achromatic, shock absorbed
• magnification: 45x
• numerical aperture: 0.65
• Standard thread diameter: 20 mm 2 years
