# Description and specifications:
Carl Zeiss Jena Jenaval / Jenamed microscope widefield binocular head with 30 mm GF-Pw 10x (25) eyepieces

Microscope head parameters:
Manufacturer: Carl Zeiss Jena
Name: Grossfeld Binocular
Eyepiece mounting diameter: 30 mm
Microscope mount: 41 mm dovetail mount
Diopter adjustment: yes, for one eyepiece

The set also includes two eyepieces:
- Model: Carl Zeiss Jena GF-Pw 10x (25)
- Mounting diameter: 30 mm

This head is most commonly used in the following microscopes:
- Carl Zeiss Jena Jenamed
- Carl Zeiss Jena Jenaval
- Carl Zeiss Jena Jenalumar
- Carl Zeiss Jena Jenapol
- Carl Zeiss Jena Jenvert
- Carl Zeiss Jena Jenatech
- Carl Zeiss Jena Jenalab

Interestingly, widefield binocular heads with a 30 mm eyepiece mounting diameter are sometimes also installed in older Mikroval series microscopes (for example Ergaval and Amplival). If the microscope is additionally equipped with GF-Planachromat series widefield objectives (or GF-Planapochromat objectives used in Docuval microscopes) - this creates the best possible combination for Carl Zeiss Jena microscopes with a 160 mm tube length.

This microscope head model is identical to the Baader Mark V binocular viewer used in astronomical telescopes and is often purchased by astronomy enthusiasts and adapted for telescope mounting.

# Examples of use
- if you currently have a head designed for 23.2 mm eyepieces and want to replace it with a widefield head using 30 mm eyepieces
- if you want to adapt this head for use with an astronomical telescope
