GRIN Assemblies
for Imaging

Precision for every application
Endoscopic assemblies often consist of biocompatible GRIN objective lenses and other micro-optical components such as GRIN relay lenses, image-guiding fiber bundles, prisms and beam splitters.
- GRIN objective lenses are made of non-toxic glass material (biocompatibility according to EN ISO 10993-1). With standard diameters between 0.25 and 2.0 mm, they have plane optical end faces. GRIN objective lenses with viewing angles of +/- 30° are mainly used for endoscopic applications
- In endoscopic assemblies, GRIN objective lenses produce a reduced intermediate image in the size of the lens diameter, which is transmitted over longer distances with relay lenses. Optical design files (ZEMAX) are available on request.
- We offer customer-specific assemblies made of GRIN lenses with image-guiding fiber bundles.




Customizable at the customer’s request:
On request, the following are possible:
- Working distance and lens length changes
- Design wavelength change
- Photolithographically generated apertures on GRIN end faces
