This is description of this part:
Primo Plan-ACHROMAT 4x/0.10 ∞/- microscope objective by Carl Zeiss for Zeiss Primostar / Zeiss Primovert microscopes.
Basic parameters of this objective:
Manufacturer: Zeiss
Magnification: 4x
Correction: plan achromatic
Engraving on the objective: Primo Plan-ACHROMAT 4x/0,10 ∞/- 415500-1600
Numerical aperture N.A.: 0.10
Working distance WD: 12.0 mm
Manufacturer catalog number: 415500-1600

This objective works properly only with the Zeiss Primo line (Primostar / Primovert microscopes). It does not work properly with other Zeiss microscopes, even if they also have an RMS thread and are infinity corrected. It is also suitable for reflected-light (EPI) work.
For the microscope models of the Zeiss Primo line, both the one-word names (Zeiss Primostar and Zeiss Primovert) and the two-word names (Zeiss Primo Star and Zeiss Primo Vert) are commonly used.
What is this part needed for?
- if an objective is missing and you want to complete your Zeiss Primostar / Primovert microscope with original parts
- if you have this objective, but it is in very poor condition
- if you want to keep this objective as a spare
