Calcium Fluoride (CaF2) Windows Dia. 12.7 mm x 5 mm, Uncoated FAQs

Q1: What are the key material properties of Calcium Fluoride (CaF2) Windows Dia. 12.7 mm x 5 mm, Uncoated ?

A1: Calcium Fluoride (CaF2) windows offer a broad transmission range from the vacuum ultraviolet (roughly 130 nm) through the infrared (around 10 µm). They have a relatively low refractive index, which reduces Fresnel losses, and they exhibit excellent thermal stability. Additionally, CaF2 possesses high laser damage thresholds, making it well-suited for high-power laser applications. Its mechanical hardness, while moderate, provides sufficient durability for many optical setups where careful handling is practised.

Q2: How should this product be handled and stored?

A2: Given CaF2’s moderate hardness, it is vital to avoid unnecessary contact with abrasive surfaces or harsh chemicals. Always wear clean gloves and use proper tweezers or lens handling tools. Store the windows in a clean, dry environment to prevent surface contamination or moisture absorption. Protect them from abrupt temperature changes, as rapid thermal shocks can induce stress fractures. If cleaning is necessary, use approved optical-grade solvents and lint-free wipes.

Q3: Which quality standards and certifications apply to Calcium Fluoride (CaF2) Windows Dia. 12.7 mm x 5 mm, Uncoated ?

A3: These CaF2 windows typically conform to ISO 10110 specifications for dimensional tolerance, surface quality, and material defects in optical components. They may also meet RoHS and REACH compliance depending on the supplier’s manufacturing processes. Suppliers often provide certificates of conformity and detailed inspection reports. In research or high-precision industries, additional certifications like MIL-PRF-13830B for scratches and digs can be requested to ensure consistent, reliable performance in demanding optical systems.
