Calcium Fluoride (CaF2) Windows Dia. 25.4 mm x 6 mm, Uncoated FAQs

Q1: What are the key material properties of Calcium Fluoride (CaF2) Windows Dia. 25.4 mm x 6 mm, Uncoated?

A1: Calcium Fluoride (CaF2) is known for its excellent broadband transmission from the ultraviolet (UV) through the mid-infrared (IR) range, making these 25.4 mm x 6 mm windows suitable for multi-spectral applications. They have a low refractive index, reducing the need for anti-reflective coatings. CaF2 also offers good environmental durability, minimal fluorescence, and a relatively high laser damage threshold. The material’s moderately soft hardness rating requires careful handling to prevent surface scratches.

Q2: How should these windows be handled and stored to maintain their performance?

A2: Given that Calcium Fluoride is relatively soft, it is crucial to handle these windows with clean gloves and avoid contact with hard surfaces or sharp tools. Use only non-abrasive cleaning materials and solvents suitable for optical components. Store them in a protective container with cushioned compartments, maintaining a low-humidity environment to minimise potential surface damage. Proper handling and storage practices help extend the windows’ operational life and ensure performance.

Q3: Which quality standards and certifications apply to Calcium Fluoride (CaF2) Windows Dia. 25.4 mm x 6 mm, Uncoated?

A3: These windows typically adhere to global optical component standards, such as ISO 10110, for surface accuracy and transmitted wavefront error. Manufacturers often comply with ISO 9001 for quality management and may provide documentation detailing scratch-dig specifications (e.g., MIL-PRF-13830B) to verify surface quality. Some suppliers also certify metrology calibration against NIST-traceable standards, ensuring consistent dimensional and optical compliance for reliable performance.
