What type of interferometer do I need to use a CGH?
AOM products are well suited to pair with a number of commercial interferometer systems including Fizeau and Twyman-Green type interferometers.
Compatible models include:
- Zygo – Verifire, Dynafiz, GPI, Mark
- 4D Technologies – Accufiz, PhaseCam
- Xonox – X-fiz, X-Mini
- Apre Instruments – S-Series
- ADE Phase Shift – MiniFIZ
A variety of interferometer wavelengths can be used, as long as the test wavelength transmits through the CGH substrate. (Alternatively, a CGH can be designed to work in reflection).
