Precision finished BK7, Fused Silica and Sapphire windows available in custom sizes and machined shapes. Fine tune your reflection and transmission performance requirements with an ultra-durable low loss multi-layer thin film coating. Using high energy deposition techniques, we offer low stress, conductive (ITO), high reflection and enhanced metal mirrors as well as low absorption antireflection coatings. Our advanced metrology and testing laboratory measures performance characteristics for each optic including finish, wavefront, reflection, transmission, vacuum/leak detection, defect mapping and surface quality. From initial samples for development to low-volume production, we offer solutions for your specialized needs.

YAG Ultra High Vacuum Viewports

MPF has created a NEW Ultra High Vacuum Viewport using YAG lens material. We have added YAG material to our long-standing traditional materials of Fused Silica and Sapphire. MPF has been manufacturing hermetically sealed viewports for over 30 years, and we are so excited about our NEW addition. This development continues in the tradition of MPF being ingenious and ground cutting in being problems solvers in the vacuum components and vacuum systems marketplace.
