            BK7?Optical Glass

            BK7® glass is a type of high-quality optical crown glass, often used for the production of lenses, windows, mirrors and other optical components. It is very clear and colorless and is commonly used as a cost-effective alternative to fused silica when operating conditions allow. It is a reasonably hard material and has good scratch resistance.

            The properties of this glass make it particularly suitable for use as a technical material in many laser and other optical systems.

            Characteristics of BK7® optical glass include:

            • Good transmission properties in the visible and near infrared regions
            • Low bubble and inclusion content
            • Very clear and colorless appearance
            • High homogeneity
