Calcium Fluoride (CaF2) Windows 5 mm x 5 mm x 1 mm, Uncoated FAQs

Q1: What are the key material properties of Calcium Fluoride (CaF2) Windows 5 mm x 5 mm x 1 mm, Uncoated ?

A1: Calcium fluoride is highly transparent from the deep ultraviolet (UV) range to the mid-infrared (IR), making it particularly useful for broadband optical applications. Its relatively low refractive index (~1.43 at 10 µm) minimises Fresnel reflections, while its high laser damage threshold and excellent radiation resistance enhance performance in demanding environments. The material also boasts good thermomechanical stability and chemical inertness, supported by low hygroscopicity.

Q2: How should this product be handled and stored?

A2: Because CaF₂ is relatively brittle, handle these windows with clean, lint-free gloves or finger cots to prevent contamination. Use only non-abrasive wiping materials and compatible solvents (e.g., isopropanol) for any cleaning. Avoid applying force at edges to reduce chipping or fracturing. Store them in a dry, dust-free environment, preferably in protective packaging or containers that cushion against mechanical shock and protect optical surfaces from scratches.

Q3: Which quality standards and certifications apply to Calcium Fluoride (CaF2) Windows 5 mm x 5 mm x 1 mm, Uncoated ?

A3: Calcium Fluoride (CaF2) optical components typically comply with ISO 10110 guidelines for surface quality, scratch-dig specifications, and dimensional tolerances. Manufacturers often adhere to the MIL-PRF-13830B standard for cosmetic defects in precision optical elements. RoHS (Restriction of Hazardous Substances) compliance may also be relevant if required by the application. Ensuring strict adherence to these standards guarantees consistent optical performance, dimensional accuracy, and reliability in demanding environments.
