Optical metrology is a branch of science and technology concerned with the precise measurement of physical quantities using light. It involves using light waves to measure distances, surface profiles, refractive indices, and other optical properties. Fiber lasers are particularly well-suited for this application due to several key attributes that align with the demands of high-precision measurements. 

Our fiber lasers possess long coherence length, which is crucial for interferometric techniques used in optical metrology. High coherence length allows for precise phase measurements, enabling accurate distance and surface profile measurements. They are also incredibly stable, which is essential for consistent and repeatable measurements. This stability minimizes drift over time, improving measurement accuracy.

Look no further than MPBC’s line of single-frequency fiber lasers, which offer a true diffraction limited beam with M² < 1.1, unprecedented beam pointing and power stability, and maintenance-free turn-key operation, all within a low power consumption compact package.
