Borosilicate Window Dia. 12.5 mm x Thk. 1.75 mm, MgF2 Coated FAQs

Q1: What are the key material properties of Borosilicate Window Dia. 12.5 mm x Thk. 1.75 mm, MgF2 Coated?

A1: Borosilicate glass provides mechanical strength, minimal thermal expansion (approximately 3.3 x 10^-6 K^-1), and high chemical resistance, making it ideal for demanding optical applications. This 12.5 mm diameter, 1.75 mm thick window is further optimised by a magnesium fluoride (MgF2) antireflection coating, resulting in increased transmission from UV to near-infrared wavelengths. The coating also minimises surface reflections, enhances contrast, and improves the overall optical performance in scientific and industrial setups.

Q2: How should this product be handled and stored?

A2: To protect the window’s precision surfaces, always handle it with clean, lint-free gloves to avoid skin oils or contaminants. Keep the MgF2-coated side free from contact with hard materials that might cause abrasions. Store the window in a clean, dry environment, ideally in its original packaging or a dust-free container. Avoid exposing it to sudden temperature changes or corrosive chemicals that could compromise its optical quality.

Q3: Which quality standards and certifications apply to Borosilicate Window Dia. 12.5 mm x Thk. 1.75 mm, MgF2 Coated?

A3: These windows are commonly manufactured under ISO 9001-certified processes to ensure consistent quality, traceability, and customer satisfaction. Optical surfaces may also comply with MIL-PRF-13830B standards, which detail scratch-dig specifications for precision optics. Depending on the specific application, suppliers often provide evidence of RoHS compliance, confirming limited hazardous substance content. Additionally, thorough inspection procedures and batch certifications guarantee the product meets stringent optical and mechanical performance requirements.
