PRODUCT OVERVIEW
Introduction
N-BK7 windows are optical windows manufactured from BK7 optical glass, a high-quality borosilicate crown glass known for its excellent optical homogeneity, low bubble and inclusion levels, and reliable transmission performance. As a widely used optical material, BK7 provides a balanced combination of optical clarity, mechanical stability, and cost efficiency for precision optical components.
BK7 optical windows provide a flat and stable optical interface for protecting optical systems while allowing light transmission with minimal distortion. The material’s good visible and near-infrared transmission range, low thermal expansion, and consistent optical properties make it a versatile choice for many optical designs.
