266nm or 4μm Design Wavelength Options
High Transmission from 200nm to 7μm
Diamond Turned for High Surface Accuracy
Vacuum UV Grade CaF₂ Substrate

TECHSPEC® Calcium Fluoride (CaF₂) Aspheric Lenses have high transmission from the ultraviolet (UV) through the infrared (IR), covering the wavelength range of 200nm to 7μm. Calcium fluoride’s low index of refraction enables these diamond turned aspheric lenses to be integrated with minimal Fresnel reflection loss without an anti-reflection coating. Calcium fluoride also offers low solubility and superior hardness compared to other fluoride-based substrates, allowing for these aspheric lenses to be used in harsh environments. TECHSPEC Calcium Fluoride (CaF₂) Aspheric Lenses are available in two designs; one for Nd:YAG, Excimer Laser, and other UV applications with a design wavelength of 266nm and the other for spectroscopic, mid-wave IR (MWIR) thermal imaging, and other IR applications with a design wavelength of 4μm.
