Thorlabs UHV-Compatible Fiber Feedthrough
The Thorlabs UHV-Compatible Fiber Feedthrough is designed for coupling optical fiber into ultra-high vacuum (UHV) systems. It is typically used in scientific and industrial applications where maintaining vacuum integrity is crucial, such as in research laboratories and semiconductor manufacturing.
Specifications to confirm include flange options (CF Ø2.75-inch and KF40), fiber type (hermetically sealed step-index multimode), connector type (SMA905), insertion loss (≤2.3 dB), and maximum optical power (1 W). Buyers should also discuss MOQ, packaging options, and lead times with suppliers.
Thorlabs fiber feedthroughs couple optical fiber into UHV systems using hermetically sealed multimode fiber and vacuum flanges.
