Technical Overview
UHV viewports transmit light into or out of a vacuum chamber through a fused silica or sapphire window brazed to a metal flange. Fused silica covers 200–3500 nm; sapphire extends from 180 nm to 5000 nm with higher mechanical strength.
Typical Applications
- Plasma and vacuum process observation
- Optical spectroscopy and laser experiments
- Particle-beam diagnostics
- X-ray and synchrotron systems
