A borosilicate crown glass, BK7 is relatively hard, does not scratch easily, and can be handled without special precautions. Good performance over visible and near IR spectrum for most application.

The ideal window allows the optical beam to pass unimpeded and unchanged with high durability according to requirement of applications. In order to come close to this ideal, our windows and optical parallels are manufactured considering with transmittance, homogeneity, sub-surface damage, surface flatness and parallelism of the materials or in polishing processes to achieve high transmittance, low wavefront distortion and low scatter.

Non-coated and AR coated products are available.
