Lithium Fluoride Window (LiF) Dia. 25.4 mm x 2 mm, Uncoated FAQs

Q1: What are the key material properties of Lithium Fluoride Window (LiF) Dia. 25.4 mm x 2 mm, Uncoated?

A1: Lithium Fluoride (LiF) is known for its broad transmission range from the vacuum UV (~105 nm) into the infrared (~6 μm). With a refractive index near 1.39 at 1 μm, it is highly transparent. It exhibits good thermal stability, can be used in extreme temperature environments, and offers low birefringence. Its moderate hardness allows for precise optical finishing, although it is relatively brittle compared to other crystalline materials.

Q2: How should this product be handled and stored?

A2: Lithium Fluoride windows should be handled with powder-free gloves to avoid contamination, as any residue can affect optical performance. Store them in a clean, low-humidity environment at room temperature to reduce moisture absorption, which can degrade surface quality. Avoid sudden temperature changes to prevent stress fractures. When cleaning, use mild solvents and non-abrasive materials, taking care not to apply excessive pressure to the window’s brittle crystalline structure.

Q3: Which quality standards and certifications apply to Lithium Fluoride Window (LiF) Dia. 25.4 mm x 2 mm, Uncoated?

A3: These Lithium Fluoride windows typically conform to ISO 10110 for optical component specification, covering surface quality, material inclusions, and dimensional tolerances. They may also meet MIL-PRF requirements for optical elements used in defence applications if specifically tested. Manufacturers often provide a certificate of conformity to verify compliance with relevant mechanical and chemical regulations. Quality checks typically include interferometric surface testing, scratch-dig inspection, and verification of material purity before shipment.
