Lithium Fluoride Window (LiF) Dia. 25.4 mm x Thk. 2.0 mm, Uncoated FAQs

Q1: What are the key material properties of Lithium Fluoride Window (LiF) Dia. 25.4 mm x Thk. 2.0 mm, Uncoated?

A1: The Lithium Fluoride (LiF) window features exceptional transparency across a broad spectral range, spanning from the vacuum ultraviolet (VUV) through the infrared region (about 120 nm to 6 µm). It has a low refractive index and excellent radiation resistance. LiF is relatively soft (Mohs hardness ~ 3), making it easier to scratch than harder materials. It possesses good thermal stability but should be protected from moisture to maintain optimal optical performance.

Q2: How should this product be handled and stored?

A2: Store LiF windows in a clean, dry environment to prevent reactions with moisture or other contaminants. Always handle them with powder-free gloves to avoid fingerprint residues and scratches on the surface. Avoid exposing them to rapid thermal changes, as LiF can be more susceptible to thermal shock. Protective caps or packaging should be used during transit to minimise impact and surface damage.

Q3: Which quality standards and certifications apply to Lithium Fluoride Window (LiF) Dia. 25.4 mm x Thk. 2.0 mm, Uncoated?

A3: For Lithium Fluoride windows of this specification, manufacturers typically follow ISO 10110 for optical component inspection and surface quality. Labs may also adhere to MIL-PRF-13830B for scratch-dig standards. Additionally, ANSI Z80.1 can guide certain optical tolerances. Inspections often include rigorous testing against stress birefringence, inclusions, and wavefront distortions. Conformance to RoHS or REACH requirements may be provided. Traceable documentation and certifications ensure consistent performance and compliance with industry standards.
