Optical Metrology

Precise visible and IR interferometry; flexible photometry; electron and optical microscopy; spectrophotometry; semiautomated inspection; and more. Learn More »

Cleaning & Handling

Custom processes resulting from many years of engineering and experience enable the highest damage threshold, most defect-free gratings possible. Learn More »

Design & Modeling

PGL employs sophisticated, state-of-the-art design tools for modeling diffraction grating and thin-film coating performance. These are vital not only for determining initial designs, but also for considering manufacturing tolerances which drive costs as well as for aiding the manufacturing process itself. Learn More »

Plymouth Grating Laboratory is dedicated to making the highest-quality diffraction gratings available today. Our focus is on lasers and laser systems. PGL gratings offer exceptionally high diffraction efficiency and laser damage threshold, combined with superior wavefront error and uniformity over large areas. This performance is made possible by PGL’s exclusive use of the Nanoruler, based on the proprietary Scanning Beam Interference Lithography technology developed at MIT, and PGL’s industry-leading process expertise. The company occupies 20,000 sq. ft. of dedicated manufacturing, engineering, and office space in Carver, MA, just outside of Plymouth, and about 45 miles south of Boston.
