Fiber Optic Pickups
ZMI Series - Displacement Measuring Interferometers
Zygo offers three fiber optic pickups (FOPs) to meet the needs of various applications. The standard FOP is low cost, and effective for most non-vacuum applications. The vacuum compatible FOP has a fully vented monolithic stainless steel housing and is epoxy-free.
The large clear aperture FOP offers the same benefits as the vacuum compatible FOP and an 18 mm input aperture for large beam or large beam shear applications.
