Product Description

Interferometer MarOpto FI 3100 VB

Simultaneous phase-shifting Fizeau interferometer is a real-time, high-speed, truly vibration insensitive metrology instrument with shutter speeds as fast as 10 μs. Ideally suited for shop/production floors, the interferometer MarOpto FI 3100 VB offers unsurpassed measurement accuracy, stability and repeat-ability. Mahr’s new SPARC technology ensures measurement errors of less than λ / 100 with no vibration isolation.

Features

Application   Measurements of flat, concave and convex surfaces of any size, Measurements over long distances, including in vacuum chambers, In-situ measurements of optical, machined and wafer surfaces, Dynamic measurements for thermodynamic events, moving objects, etc. Characterization and removal of birefringence effects
