Zygo® GPI-XP to Verifire Interferometer, 1200 x 1200 Camera

Digital CAN Verifire upgrade is performed that converts the GPI interferometer from analog electronics to CAN-based digital electronics. Installed are new digital cameras and new frequency-stabilized laser. The upgrade also includes a new Dell computer running Windows 11 and the latest version of Mx software. Upgrade performed by Zygo service. Zygo warranty – 1 year for the system and 3 years on the Dell computer. Very modern and supportable phase measuring interferometer when completed. Super sweet! 4-inch is $59,500 and 6-inch is $69,500

I have a 4″ GPI-XP in the pipeline to be upgraded to a VeriFire.  It is in the works but it will be 4-8 weeks before we can ship.

Point Diffraction Interferometer (PDI) plates manufactured in Germany – 2nd generation – $100

With these plates it’s very easy to build a point diffraction interferometer, for example for testing a telescope mirror. You only need a cheap red laser diode (without collimating lens), the PDI plate, a 3-axis stage, and a camera.
