Numerical aperture: 0.12
Tube length: 160 mm

Thread: RMS
Info: EF = Ebenes Feld (plan field)
Info: P = Polarizing (stain-free lens with anti-reflective coating)
Leitz P/N: 559212

This lens provides an excellent, wide image, and because it doesn't require a cover glass, it's often used for super-macro photography and stacking.

Of course, the "P" designation doesn't mean it's designed "solely" for polarizing. It can be used in any microscope for both polarization, brightfield, transmitted light and reflected EPI.

# Examples of use
- If you have a microscope from any brand that lacks an objective lens with this magnification
- If you have such a lens, but it is of very poor quality or damaged
- If you want to replace your 4x objective lens with one of excellent quality
- If you are cautious and want to have such a lens on hand
