GRIN Rod Lenses  

Precision for every application

GRIN rod lenses are made of non-toxic glass material (biocompatibility according to EN ISO 10993-1). With standard diameters between 0.35 and 2.0 mm, they have plane surfaces and numerical apertures of 0.2 and 0.5. GRIN lenses with a numerical aperture (NA) of 0.5 are preferably used for fiber coupling and laser diode beam shaping. GRIN lenses with an NA of 0.2 have longer focal lengths and lens lengths. Optionally, we also offer these with better correction of spherical aberration (high performance).

GRIN objective lenses with viewing angles of +/- 30° are mainly used for endoscopic applications, e.g. in conjunction with image guide bundles or GRIN relay lenses.

Customizable at the customer’s request:

On request, the following are possible:

  • Working distance and lens length changes
  • Change of design wavelength
  • Anti-reflective coatings
  • 8° facet polishing
  • Other diameters, e.g. 0.25, 0.35, 0.6 and 0.85 mm
