Synthetic fused silica be Harder and more shock resistant than BK7, and with a low coefficient of thermal expansion, fused silica windows can operate over a much wider thermal range. They are also have much higher resistance to radiation darkening from ultraviolet light, X-rays, gamma rays, and neutrons.
It is ideally siuted for application from UV to IR specetrum.
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.
