Precision Viewport Windows from UV Fused Silica and BK7 - UV Fused Silica Viewports for UHV Applications

25 Mar 2019

The advancement in technology such as in the semiconductor industry and with the development of novel experiments to model extreme atmospheric conditions and free space, has given rise to a boom in vacuum technologies. Vacuum systems reduce the pressure of a space to a level lower than atmospheric pressure by removing gas particles. Applications include semiconductor processing and pharmaceutical drug development where the need for contamination control is paramount.

Viewports are integrated into vacuum chambers to facilitate visual observation of processes and illumination tasks. Certain experiments/processes must be performed under vacuum such as surface analytical techniques include X-ray photoelectron spectroscopy and ion traps.

LASER COMPONENTS manufactures precision viewport windows from UV fused silica and BK7. These viewports can be AR coated to the customer’s desired operating wavelengths between 193nm to 5000nm and have typical LIDT values of 10J/cm2 (10ns@1064nm). Alternative materials can be utilised depending on the operating wavelengths to minimise absorptions. These viewports can be manufactured to a variety of sizes and high levels of surface irregularity (Lambda/8) and surface quality (20-10), ensuring minimal scattering losses.
