Potassium Bromide Window (KBr) Dia. 50.8 mm x Thk. 3.0 mm, Uncoated FAQs

Q1: What are the key material properties of Potassium Bromide Window (KBr) Dia. 50.8 mm x Thk. 3.0 mm, Uncoated ?

A1: Potassium Bromide (KBr) is highly transparent in the infrared range, typically transmitting from about 0.2 µm to 25 µm. It has a refractive index of approximately 1.486 at 10 µm and is relatively soft and brittle. KBr is also hygroscopic, meaning it readily absorbs moisture from the air, which can cause surface degradation if not properly protected. Its low hardness requires careful handling.

Q2: How should this product be handled and stored?

A2: Due to its hygroscopic nature, KBr should be handled in a low-humidity environment with gloves to prevent moisture absorption and contamination. It is crucial to store this window in a sealed, desiccated container or cabinet when not in use. Avoid direct contact with skin or harsh cleaning solutions. Gentle handling is recommended to prevent scratches or chips, which can compromise optical performance.

Q3: Which quality standards and certifications apply to Potassium Bromide Window (KBr) Dia. 50.8 mm x Thk. 3.0 mm, Uncoated ?

A3: KBr windows typically comply with ISO 10110 for optical component specifications, ensuring criteria such as surface quality, wavefront distortion, and dimensional accuracy are met. Additionally, stringent purity requirements may be verified through certifications like a Certificate of Analysis to demonstrate traceability and compliance. Some suppliers also adhere to quality management standards like ISO 9001 for consistent manufacturing processes and product reliability.
