This is description of this part:
A very rarely encountered microscope objective from EMO Optik Wetzlar, available on the secondary market.
Basic parameters:
Manufacturer: EMO Optik Wetzlar (Arthur Seibert)
Model: 75:1 0.82
Correction: achromatic
Magnification: 75x
Aperture: N.A. 0.82
Thread: RMS
Parfocal length: 45 mm
Tube length: 170 mm (most likely)
Immersion: no | dry objective | air
The description states that the tube length is most likely 170 mm. Most objectives produced in the 1950s-1970s in the so-called "Wetzlar microscope center" followed a common 170 mm standard. The company "EMO Optik" was founded by Arthur Seibert, who was trained and worked at Leitz, which suggests the use of the 170 mm standard commonly used by Leitz at that time.
There is very little information available about microscopes manufactured by EMO Optik Wetzlar, therefore the exact microscope model from which this objective originates is unfortunately unknown.
What is this part needed for?
- if you own an EMO Wetzlar microscope and are completing it with original parts
- if you have another microscope with a 170 mm tube length and want to use high-quality optics
- if you are a collector and want to add such a rare item to your collection
