This is description of this part:
Polarization-interference microscope objective by PZO
Basic parameters:
Manufacturer: PZO Poland
Model: 10/0,24 PI 160/-
Magnification: 10x
Correction: Achromat
Numerical aperture: 0.24
Tube length: 160 mm
Focal length: 45 mm
Cover glass: no
Immersion: no
Thread: RMS
Info: PI = polarization-interference objective (red ring).
Compatible with the following PZO condensers:
- PZO KPI 2
- slit condenser
PI objectives are among the components of the PZO UPI set (i.e. the so-called DIC).
VERY IMPORTANT: the marking on the objective is "PI" (in lowercase: "pi"), meaning [P]-polarization [I]-interference.
In many descriptions available on the Internet, you can find information that this is a PLAN objective. This is an ERROR caused by misinterpreting the marking as PL.
Note: another INCORRECT piece of information often found online is that these are DIC objectives. This is not true.
DIC according to Pluta (niem: DIC nach Pluta), sold by PZO, achieves the DIC effect (i.e. a 3D relief image) using standard achromatic PZO objectives (and not only those). Objectives marked PI with a red ring are not required for this.
It can be used with any microscope from any manufacturer that supports RMS objectives, TL=160 mm, FL=45 mm.
What is this part needed for?
- if you have an incomplete PZO UPI DIC set missing this exact objective and want to complete it
- if you need a polarization-interference objective for your own purposes
- if you have such an objective but it is of very poor quality or damaged
- if you want to keep such an objective as a spare
