tauFRIN - Transmission Spheres

5"+ Transmission Spheres for 4" Fizeau interferometers

Key τFRIN benefits:

  • Expander + Transmission Sphere
    • two-component aplanatic design
    • with replaceable transmission spheres
  • wide range of F/# from 1:7.1 to 1:0.65
  • fast replacement without turning of transmission spheres
  • λ = 633 nm, versions for 532 nm, 1064 nm and other wavelengths available by request
  • Expander’s 4" bayonet of the "state-of-the-art design" can be customized
  • enhanced capabilities due to internal expansion of 4" input beam:
      extended ranges of radii and diameters for surfaces to be tested
  • optimized for optical shop testing
  • compatibility with major 4" interferometers
  • accuracy of reference surfaces λ/15
  • owing to installation features suitable for horizontal and vertical test schemes
  • convenient colour marking
