What Is BK7 Glass?
BK7 glass is a high-quality borosilicate crown optical glass widely used in scientific, industrial, and semiconductor applications. It offers excellent transmission throughout the visible and near-infrared spectrum, low optical distortion, and outstanding homogeneity, making it one of the most popular materials for precision optical components. BK7 is commonly manufactured into BK7 glass wafers, optical windows, lenses, prisms, and custom substrates for research and production environments.
Because BK7 combines excellent optical performance with good mechanical durability and cost-effectiveness, it is frequently selected as an alternative to more expensive optical materials when UV transmission or extreme thermal resistance is not required.
