Description
Carl Zeiss Jena Jenaval / Jenamed microscope GF-Planachromat 40x/0.65 oo/0,17-A objective, infinity, M25-threadMicroscope objective from Carl Zeiss Jena.
Basic parameters of the objective:
Manufacturer: Carl Zeiss Jena
Model: GF-Planachromat 40x/0.65 oo/0,17-A
Magnification: 40x
Numerical aperture N.A.: 0.65
Optical correction: planachromatic
Additional: "GF" = Grossfeld, meaning a wide field objective
Tube length: infinity
Thread: M25
Cover glass: yes, 0,17 mm
Immersion: no
This objective fits, among others, the following microscopes:
- Carl Zeiss Jena Jenamed
- Carl Zeiss Jena Jenalab
- Carl Zeiss Jena Jenaval
- Carl Zeiss Jena Jenalumar
For the Carl Zeiss Jena Jenamed microscope, this objective fits every variant:
- Carl Zeiss Jena Jenamed variant
- Carl Zeiss Jena Jenamed Fluorescence
- Carl Zeiss Jena Jenamed hematology
- Carl Zeiss Jena Jenamed cytology
- Carl Zeiss Jena Jenamed 2
The best image quality and full performance of this objective are achieved when using a Carl Zeiss Jena microscope head supporting 30 mm eyepieces and eyepieces marked "GF", meaning - similarly to the objectives - wide field eyepieces.
An interesting fact is that I very often see this objective (as well as other Carl Zeiss Jena objectives with M25 thread) mounted in Leica microscopes (for example Leica DMLB or Leica DMLS). Carl Zeiss Jena objectives are slightly shorter than Leica ones, so users apply extension adapters in such cases.
