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.

Coatings and Applications

We offer a large selection of coatings and applications for our UHV viewports. Our methods include Evaporation, E-Beam, Ion Assist, and High Energy Plasma. Anti-Reflective, Indium Tin Oxide (ITO), Broadband (BBAR), V-Coat, Dual AR, Multi-Band AR, and Reflective Coatings can all be processed on any of the viewport offerings. Please call or e-mail us to discuss your specific application with one of our sales representatives.

MPF Products, Inc. does not approve the use of ultrasonic cleaning for any viewport. We ship our viewports UHV ready. You may simply blow off the glass to remove any contaminants with clean, dry air. For additional cleaning steps for particulates or contamination from other processes, please review our cleaning procedures at UHV Viewport Cleaning Notes.
