UV grade LiF optics is used in research on Ultra-High-Frequency Electronics contact us for a custom quote for LiF optics

Application note

Customer inquiry: I would like to order material that is transparent to vacuum UV light, in particular to 104.8nm photons that are generated by an Ar plasma.
My research has led me to Lithium Fluoride as a suitable material. Do you stock LiF or any windows that transmit 104nm photons?

Customer research area:

Ultra-High-Frequency Electronics

* III-V Transistors
* III-V Integrated Circuits
* mm-wave CMOS & BiCMOS ICs
* wideband fiber optics
* mm-wave RF/wireless
