Featuring a low refractive index and high laser damage threshold, CaF₂ windows transmit from VUV to IR. They are ideal for excimer lasers and low-fluorescence spectroscopy.
Calcium fluoride exhibits a low refractive index, along with mechanical and environmental stability. It demonstrates high damage threshold, low fluorescence, and excellent homogeneity, making it the ideal choice for any demanding applications requiring these properties.
