Optical System Testing

Our optical testing instrumentation enables us to make a wide range of measurements on optical systems including various measures of image quality, first order system characteristics, individual element parameters, and many more.

  • Relative Spectral Transmission
  • Total Transmission
  • Stray Light
  • Veiling Glare

Lens Characteristics

  • Effective Focal Length
  • Flange Focal Length
  • Back Focal Length
  • F-Number
  • Entrance and Exit Pupil Diameters

Element Characteristics

  • Radius of Curvature
  • Center Thickness
  • Diameter
  • Index of Refraction
  • Abbe Number
  • Surface Irregularity
