The chemical properties of BK7 are very stable, so it possesses scratch resistance and corrosion resistance. Meanwhile special grinding and polishing processes are not required, thereby reducing manufacturing costs. BK7 has a high degree of purity and homogeneity. It is nearly free of bubbles and inclusions. The BK7 is clear and colorless, and has very high transmittance in the visible and near-infrared spectrum (350 nm-2.0 µm). Therefore, it is suitable for most spectral ranges and has become the most widely used glass material.

However, if you need further applications in the UV spectrum or a lower coefficient of thermal expansion, we recommend that you use UV Fused Silica Windows.

The highest standard for BK7 windows is 10-5 scratch dig, which reaches precision laser quality. BK7 windows are an economical choice for low power lasers and medium power lasers. Because of high transmittance in the visible light range, BK7 windows can be used in imaging systems as protective displays for a variety of industrial or environmental applications.

can provide you with a range of high-quality N-BK7 windows, including N-BK7 round windows, N-BK7 square windows, step windows, N-BK7 precision windows, custom N- BK7 windows.
