OP8349 Lithium Fluoride Window (LiF) Dia. 10 mm x Thk. 1.0 mm, Uncoated

Lithium Fluoride Window (LiF) Dia. 10 mm x Thk. 1.0 mm, Uncoated Description

This 10 mm diameter × 1.0 mm thickness uncoated Lithium Fluoride (LiF) window is designed to deliver optimal performance across a broad spectral range, from the vacuum ultraviolet (VUV) region to the infrared. The wide bandgap of LiF (approximately 14 eV) ensures high transparency in the UV while maintaining clarity in longer wavelengths. Its low refractive index and minimal birefringence make it suitable for precision optical arrangements that require reliable, distortion-free transmission.

Manufactured under strict quality controls, each LiF window is polished to achieve a smooth, defect-free surface that complies with dimensional tolerance standards. The result is a durable optical component regularly selected for spectroscopy, interferometry, and laser applications requiring strong radiation resistance and minimal absorption losses. It is a suitable choice for scientific research and advanced optical instrumentation.

Q1: What are the key material properties of Lithium Fluoride Window (LiF) Dia. 10 mm x Thk. 1.0 mm, Uncoated ?

Lithium Fluoride (LiF) is known for its exceptional optical transmission across a wide wavelength range, extending from the vacuum ultraviolet (VUV) to the infrared (IR). It exhibits a relatively low refractive index and high radiation resistance, making it suitable for high-energy applications. LiF is softer than many other optical materials and may scratch more easily, but it offers good environmental stability under most laboratory conditions.

Q2: How should this product be handled and stored?

It is crucial to handle LiF windows with clean, lint-free gloves or tweezers to avoid surface damage. Avoid applying pressure on the window’s edges, as LiF can be brittle. Store the optic in a clean, dry environment, ideally within a protective container to prevent scratches and contamination. Keep away from harsh substances and abrasive materials that may degrade or scratch the uncoated LiF surface.

Q3: Which quality standards and certifications apply to Lithium Fluoride Window (LiF) Dia. 10 mm x Thk. 1.0 mm, Uncoated ?

High-quality LiF windows typically conform to ISO 10110 specifications for optical components, ensuring precise surface quality and dimensional accuracy. Additional certifications may include RoHS compliance for restricted substance use and adherence to manufacturing process standards such as ISO 9001 for quality management. Material purity is verified through documented certificates of conformity, confirming that the LiF meets stringent performance and safety requirements for its intended application.
