Application-specific interferometer lenses

Interferometer lenses from SwissOptic are used by our partner Mahr GmbH for the novel “MarSurf TWI 60” tilted wave interferometer (TWI) in order to quickly and flexibly measure aspheres and free-form surfaces.

Key characteristics of the 4” interferometer lens with f/0.74 include

  • Operational wavelength of 532 nm
  • Input aperture of 4“ = 101.6 mm
  • F-number of f/0.74
  • Can be used both along axes as well as for field angles of up to ±7.5°
  • Calibrating the entire interferometer system requires good wavefront quality with a low mid-frequency share of errors
