Silicon Window (Si) Dia. 25.4 mm x Thk. 1.0 mm, Uncoated FAQs

Q1: What are the key material properties of Silicon Window (Si) Dia. 25.4 mm x Thk. 1.0 mm, Uncoated?

A1: Silicon (Si) offers high thermal conductivity around 149 W/m·K, a high refractive index (~3.42 in mid-IR range), and good IR transmission from approximately 1.2 µm to 7 µm. This material also has a low density (2.33 g/cm³), moderate hardness (Mohs ~7), and minimal internal stress for stable optical performance. The uncoated surface ensures broad-spectrum compatibility, although its reflectivity may be higher without an anti-reflection coating.

Q2: How should this product be handled and stored?

A2: As silicon windows can be brittle and prone to scratching, they should be handled with lint-free gloves and clean, non-abrasive tools. Avoid direct finger contact or contact with hard surfaces to prevent chipping. Store the window in a protective case with cushioned compartments, ideally in a low-humidity, dust-free environment. Proper labeling, minimal exposure to sudden temperature changes, and gentle cleaning techniques further maintain its optical quality.

Q3: Which quality standards and certifications apply to Silicon Window (Si) Dia. 25.4 mm x Thk. 1.0 mm, Uncoated?

A3: Manufacturers typically adhere to ISO 9001 quality management practices, ensuring consistent production and traceability. Silicon windows commonly conform to MIL-PRF-13830B or ISO 10110 for surface quality, scratch-dig specifications, and flatness tolerances. They may also be fabricated under cleanroom conditions to restrict contaminants and maintain optical purity. In addition, many producers ensure compliance with RoHS directives to avoid restricted substances in the final product.
