MPF Products, Inc. specializes in designing and manufacturing UHV Viewports for scientific & harsh environment applications that require excellent atomic level hermeticity. MPF designs use UV and EUV grade Sapphire and Fused Silica to various metals.

MPF has over 175 standard designs on our website, while our engineering team has produced hundreds of specialty viewport designs over the last twenty years. Our extensive inventory levels of titanium and 316LN materials can easily translate into truly non-magnetic windows for your demanding environment.

Our Anti-Reflective (AR) and Indium-Tin-Oxide (ITO) Coated viewports have shipped globally for use in Laser Applications including KrF, XeCl, ND-YAG and Helium Neon lasers. We have also partnered with our customers to construct viewports for Differentially Pumped, Wedged, Brewster Angled, Large Viewing, Re-Entrant, Water-Cooled, Over Pressure and NIR/IR applications.

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.
