This is description of this part:
Planachromatic microscope objective with 10x magnification for the Optika Italy B-383POL polarizing microscope.
Manufacturer: OPTIKA (Italy)
Marking on the objective: IOS N-PLAN POL 10x/0.25 ∞/0.17
Manufacturer catalogue number: M-145P
Magnification: 10x
Correction: PLAN achromatic
Optical system: IOS (Infinity Optical System - Optika's own tube lens)
Numerical aperture N.A.: 0.25
Working distance W.D.: 5.8 mm
Tube length: infinity
Parfocal distance: 45 mm
Field number F.N.: 20
Cover glass: according to the marking on the objective - yes, 0.17 mm thick, although objectives of such low magnification can usually also be used without a cover glass
Immersion: no (this is a dry objective)
Thread: RMS
Polarization: yes, this is a strain-free objective - the glass and the mount are selected so that they introduce no birefringence of their own, since otherwise the background would never be black between crossed polarizers
The OPTIKA B-383POL microscope is the polarizing version of the biological OPTIKA B-380 microscope. This objective can be used both in the B-383POL and in the B-380.
What is this part needed for?
- if you own the Optika B-383POL polarizing microscope or the biological B-380 and this objective is missing
- if you already have such an objective in your microscope, but it is in very poor condition or damaged
- if you want to have such an objective as a spare
