Description
Zeiss OPMI 3 / Vario (Opton) surgical microscope 1,6x T* (30 16 68) auxiliary photo objective magnification lens with 48 mm mounting dovetail and holder for 30 mm filter1.6× auxiliary magnification objective for the photo adapter of Zeiss OPMI / Opton OPMI surgical microscopes.
This objective provides additional magnification, improves camera sensor coverage and helps eliminate vignetting when using a photographic camera (e.g. a DSLR) or a digital camera connected to a Zeiss (Opton) OPMI surgical microscope via a photo adapter.
Mechanically, this objective is installed between the photo adapter and the camera. It also incorporates a holder for an additional 30 mm filter positioned in the optical path (for example, a polarizing filter, neutral-density filter or colour filter).

▼ More about this microscope part
Note regarding the manufacturer's name: Carl Zeiss West Germany marketed its OPMI surgical microscopes (and their accessories) under the following names:
- Zeiss OPMI
- Opton OPMI
These are the same microscopes and the same components.
When the name "Opton" appears, it is printed on the label, while the word "Zeiss" underneath has often been washed off, worn away or scraped off at the factory. The reason for the deliberate removal of the "Zeiss" name and the use of the "Opton" name was an agreement with Carl Zeiss Jena, which operated in the former Eastern Bloc (communist bloc), to avoid using the name "Zeiss" on export products.
