Lithium Fluoride Window (LiF) Dia. 20 mm x Thk. 2.0 mm, Uncoated FAQs

Q1: What are the key material properties of Lithium Fluoride Window (LiF) Dia. 20 mm x Thk. 2.0 mm, Uncoated?

A1: Lithium Fluoride (LiF) windows offer excellent broadband transmittance from the vacuum ultraviolet (VUV) range through the infrared, making them suitable for diverse optical applications. They have a relatively low refractive index (approximately 1.39 at 0.59 µm), high damage threshold, and good chemical stability in dry environments. However, LiF is relatively soft, with a Mohs hardness around 4, so care should be taken to avoid scratching and mechanical stress.

Q2: How should this product be handled and stored?

A2: LiF windows should be handled with clean gloves to avoid skin oils or contaminants from damaging the surface. Avoid applying pressure directly on the optical faces. Store them in a protective container with low humidity to minimise moisture absorption, as LiF can be affected by high humidity over time. Use optics-grade cleaning materials and avoid abrasive cloths or harsh chemicals that could scratch or degrade the window.

Q3: Which quality standards and certifications apply to Lithium Fluoride Window (LiF) Dia. 20 mm x Thk. 2.0 mm, Uncoated?

A3: These LiF windows typically comply with ISO 10110 for optical component specifications and ANSI scratch-dig standards (e.g., 60-40) to ensure high surface quality. Manufacturers often maintain ISO 9001 certification for quality management, verifying consistent production and traceability. Additional testing, such as spectroscopic verification of optical properties and dimensional inspections, helps guarantee that each window meets strict specifications for scientific and industrial applications.
