WaveMaster® UST - Universal Stepper Tester
Fully automated wavefront measurement of bi-telecentric lenses

Wavefront sensor with illumination automatically measures the entire field of bi-telecentric lenses
Wavefront sensor with illumination automatically measures the entire field of bi-telecentric lenses

The WaveMaster® UST is a universal stepper optic tester (UST) and combines precise Shack-Hartmann wavefront measurement technology with expertise and experience in the manufacturing of complex measurement systems. The result is a wavefront measurement system which automatically measures the entire field of bi-telecentric lenses at multiple wavelengths. Field sizes greater than 70 x45 mm² can be measured.

 

 

Key Features

  • Full field characterization of the wavefront in large, bi-telecentric lenses (up to 300 kg in weight)
  • Maximum field size (object side): 70 x45 mm²
  • Maximum field size (image side): 100x 100 mm²
  • High degree of automation:
    • fully automatic positioning of all axes during the measurement
    • Automatic adjustment of object-side illumination and image-side sensor position
    • Automatic wavelength change during the measurement sequence
    • Usage of pre-configured measurement sequences
  • Measuring head: WaveSensor 150 with imaging optics optimized for the application
  • Autocollimator for alignment of sample tilt
  • Stable measurement system thanks to construction on a granite base, which provides extraordinary rigidity and thermal stability
  • Vibration-insulated by active air dampers
