Lithium Fluoride Window (LiF) Dia. 5 mm x Thk. 1.0 mm, Uncoated FAQs

Q1: What are the key material properties of Lithium Fluoride Window (LiF) Dia. 5 mm x Thk. 1.0 mm, Uncoated ?

A1: Lithium Fluoride (LiF) windows offer excellent transparency across a broad spectral range, including vacuum ultraviolet (VUV) to infrared (IR). With a hardness near 3 on the Mohs scale, LiF is relatively soft but demonstrates good thermal stability and low refractive index. The material has a low coefficient of thermal expansion, and it can withstand high laser fluxes due to its high damage threshold. This makes LiF suitable for specialised spectroscopy and optical applications.

Q2: How should this product be handled and stored?

A2: Handling LiF windows requires special care due to their relatively soft nature and susceptibility to moisture. They should be handled with lint-free gloves, using minimal pressure to avoid surface damage or accidental cleavage. Storage in a low-humidity, clean environment, such as a desiccator, helps prevent contamination and moisture-induced degradation. Avoid contact with finger oils and keep them in dedicated packaging to reduce the risk of scratches or chips.

Q3: Which quality standards and certifications apply to Lithium Fluoride Window (LiF) Dia. 5 mm x Thk. 1.0 mm, Uncoated ?

A3: High-quality LiF windows typically adhere to ISO 10110 optical component standards, ensuring precise surface quality, material homogeneity, and dimensional accuracy. Manufacturers may also follow MIL-PRF-13830B guidelines for scratch-dig criteria, verifying that surfaces meet strict cleanliness requirements. Additionally, RoHS and REACH compliance confirm the product is free of restricted substances. Some suppliers provide test reports or certificates of compliance to document adherence to these standards and ensure quality consistency.
