Discontinued MZI-001

Mach-Zehnder Interferometer


The MZI-001 is a fiber pigtailed Mach-Zehnder free space interferometer that detects changes in optical frequency.

Product Description

The MZI-001 free space Mach-Zehnder interferometer has two high speed photodetectors for the balanced detection of the two complementary outputs of the interferometer. The free space design eliminates much of the polarization sensitivity and free spectral range (FSR) uncertainty associated with fiber interferometers. The FSR, or zero-cross spacing, can be defined to within 2%. FSRs between 10 GHz and 100 GHz are available.
