K9/BK7 protective window

The K9/BK7 protective window is a common optical protection component with the following characteristics: 1. Material Properties: Made of borosilicate glass (K9/BK7), it has stable chemical properties, high hardness, wear resistance, and can adapt to various environmental conditions. 2. Light Transmission Performance: Its transmission range covers 350nm to 2500nm, encompassing the visible to near-infrared spectrum. It has high transmittance (typically over 90%) within common wavelength ranges, making it suitable for visible and near-infrared optical systems. 3. Protective Function: As a protective window for optical systems, it can effectively isolate dust, moisture, contaminants, and other external environmental factors, protecting internal precision optical components from damage while ensuring unobstructed light paths. 4. Processing and Customization: It can be easily processed into various shapes and sizes, supporting customized production to meet installation and performance requirements of different optical systems. Some products can also be coated with anti-reflective films, waterproof films, etc., to further enhance performance.
