Frequently Asked Questions

Why is UV grade CaF₂ better than fused silica for deep UV applications?

Fused silica has strong UV absorption below 190 nm and easily produces solarization, while UV grade CaF₂ maintains high transmittance in deep UV range and will not darken under continuous UV radiation.

Does UV grade calcium fluoride generate fluorescence under UV excitation?

No. UV grade CaF₂ single crystal has extremely low impurity content and produces almost no intrinsic fluorescence, ensuring pure UV signal output without background interference.

Can UV grade CaF₂ be used for long-term continuous UV laser work?

Yes. It features excellent thermal stability and radiation resistance, maintaining consistent optical performance and no transmittance attenuation during long-term deep UV laser exposure.
