Fiber Interferometer

Scanning Fiber Michelson Interferometer

The MIIM Series Scanning Fiber Optical Michelson Interferometer splits incoming light into two paths using a fiber optic coupler—one reference arm with a fixed fiber length and the other sample arm with a variable length controlled by either a high-speed piezoelectric fiber stretcher or a motor-driven long range delay line. Light reflected from the two fiber reflectors is recombined to produce an interference pattern for high-precision measurements. Fast scanning is achieved via the piezoelectric stretcher driven through a front-panel BNC input, while extended-range scanning is enabled by a motorized stage controlled via USB/GUI. Designed for operation across 500 to 2600 nm with matched single-mode fibers, each MIIM unit features a “zero meter” path mismatch baseline, allowing flexible delay customization.
