Optometrics Corp. recently added two laboratories to its Ayer facility, expanding the company's production of planar and concave master diffraction gratings for precision optical replication, as well as patterned beamsplitters, transmission gratings and grid polarizers. The company produces master diffraction gratings in-house for use in the production of affordable replicated reflection and transmission gratings, reducing risk to OEM customers who rely on continuous supply when the master degrades or is otherwise damaged.
