Spherical Lenses

Single lenses and lens groups

Single Lenses

Round optical components generally feature two spherical optical surfaces, one of the two surfaces can also be replaced by a plan surface.  We offer a broad range of possible specifications.

  • Scope
    • Diameters 5 to 300 mm
    • Radii from 2,5 mm to infinity
    • Form accuracies into the nanometer range
    • Complex edge and bevel structures
    • High surface accuracies
    • Can be made of optical glass or crystals
    • The focus is on chemically sensitive lenses

Lens groups

Lens groups consist of two or more round optic components which are connected by a film of putty.

  • Diameters to 200 mm
  • To putty with fast hardening, time dependent hardening, low strain and color endowed putty
  • Can be putty of optical glass or crystals
  • Precision to 0,1 min on the parasitic image
  • Prevention of diffused light by edge painting with optical coatings
  • Use of color endowed putty for different wavelength ranges
