What to expect

Operating with HeNe (632.8 nm), or 1053 nm or 1064 nm infra-red lasers (and some custom wavelengths,) PhaseCam is a small aperture surface measuring and wavefront transmission measuring interferometer for measuring optics in their functional wavelength.

With super-fast acquisition times, it’s ideal for long optical-path measurement of large focal systems, as well as deformable mirrors and adaptive optics. It’s highly popular in measuring concave telescopes mirrors and lens systems. It’s also great for testing small aperture afocal components like flat mirrors and collimators.
