Windows are most often used to separate two environments while allowing light to pass. Reflections from their surfaces can also be used to sample beams. Windows used in laser applications need to have low scatter, low absorption, low transmitted wavefront error, and high laser damage threshold. That's why all of our catalog windows are manufactured to laser quality, with 10 - 5 scratch dig surface quality, λ/10 TWE, and optional high power antireflection coatings on one or two surfaces. processing machine
