Zygo® GPI-XP to VeriFire Interferometer, 1K x 1K Camera
Digital CAN VeriFire upgrade performed that converts the GPI interferometer from analog electronics to CAN-based digital electronics. The upgrade includes a new computer running Windows 10 and the latest version of MX software. Note that Zygo no longer ships new systems with "MetroPro® classic." The GPI mainframe is retrofitted with a new electronics board and a new 1k by 1k digital camera. Upgrade performed by Zygo service. Very modern and supportable phase measuring interferometer when completed. Super sweet! 4-inch is $55,000 and sometimes a 6-inch is available for $65,000 4" system available now...new phase shifter (PMR) installed on this system. That is a $6K part!
Zygo® 4” Mark GPI XPS S/N 98-17-4207
Windows NT OS. Zygo MetroPro 7.2.2 software. Tested and working. $14,950
Zygo® 4” Mark with Zygo Phase Upgrade
Windows 7 Pro with MetroPro 9.1.4. This interferometer has been modified to have linear polarization (versus usual circular). Could be converted back to original config, but not necessary. Tested and working fine. It does have an interference "hot spot" in the center. Not an issue at low zoom, but at 6x it shows. Amount of error from the hot spot is only 0.020 waves PV, but it is visible. Could be an issue on some parts. Camera res fixed at 640x480. $17,950 SOLD

Davidson Optronics Interferometers
Point Diffraction Interferometer (PDI) plates manufactured in Germany - 2nd generation - $100
5-inch....D-305 Interferometer, completely reworked, disassembled, cleaned, re-painted, re-aligned. Like new when completed - $4,950. Add laser for $2,000 and/or add camera and monitor for $995.
2.5-inch....D-308 Interferometer, completely reworked, disassembled, cleaned, re-painted, re-aligned. Like new when completed - $4,950. Add laser for $2,000 and/or add camera and monitor for $995.
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.
