Vacuum Viewports
Vacuum viewports with fused silica, sapphire, borosilicate or specialty optical windows, configured for UV, visible or IR transmission.
Supply to technical specification; suitability and lead time are confirmed in the quotation.
State any required analysis certificate, drawing or test report. Available documents are confirmed for the product and delivery scope in the quotation.
Configure the requirement, not just the product name.
How to specify Vacuum Viewports
A vacuum viewport must satisfy both vacuum integrity and optical performance. Window material, clear aperture, wavelength range, coating, flange family, bake temperature and thermal gradients determine the correct configuration. Laser power, beam diameter and incidence angle should be stated in the RFQ when relevant.
Fused silica for UV–VIS applications
Sapphire for strength and wider thermal range
Borosilicate for general observation
AR coatings matched to the operating wavelength
Technical questions
Which viewport material should I choose?
Choose from wavelength, temperature, pressure differential, mechanical load and coating requirements.
Are vacuum viewports bakeable?
Bakeability depends on the window, braze or seal design, flange and coating; specify the required temperature.
