The FizCam family of dynamic Fizeau interferometer systems has been expanded by the introduction of the FizCam 1500. Manufactured by 4D Technology Corp., the turnkey system uses one camera and a high-speed optical phase sensor, making it insensitive to vibration and air turbulence. It performs full wavefront measurements in 30 µs and offers magnification imaging of 16× optical/digital zoom. Operating from 638 nm to 1.06 µm, the system comprises the interferometer mainframe, a Pentium IV computer system and 4Sight wavefront analysis software. Aperture options range from 100 to 600 mm.
