MPF Products Inc. offers a large variety of non-magnetic viewports.  We categorized these viewports based on their magnetic permeability. From 316LN to Titanium, MPF Products Inc. has what you need for your next application.

Additionally, MPF Products, Inc. does not approve the use of ultrasonic cleaning for any viewport. We ship our viewports UHV ready.  Due to this, 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.

Bake-Out Ramp Rate: 20°C per Minute

  • 316LN µ<1.01

    316LN µ<1.01 (25)

    These viewports utilize the low-magnetic properties of 316LN to ensure minimal magnetic interference with your most sensitive applications. 
  • Titanium µ<1.0001

    Titanium µ<1.0001 (8)

    With even lower magnetic permeability than 316LN, Titanium µ<1.0001 viewports are designed for applications where magnetic permeability must be as low as possible.
