Product Family Description

  • Low Absorption, High Transmission UV Grade Calcium Fluoride
  • Ideal for Applications Ranging from 200nm - 7μm
  • Low Index of Refraction

Calcium fluoride is often used in spectroscopic windows and lenses due to its high transmission from 200nm to 7μm. Its low absorption and high damage threshold makes it a popular choice for excimer laser optics. Calcium fluoride's low index of refraction allows it to be used without an anti-reflective coating. The Knoop hardness of calcium fluoride is 158.3. TECHSPEC® Calcium Fluoride (CaF2) Windows manufactured from vacuum UV grade calcium fluoride are commonly found in cryogenically cooled thermal imaging systems.
