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. We produce high quality optical windows / flats across a wide range of UV, visible and IR substrates. We have amassed a wealth of knowledge and developed advanced fabrication techniques to ensure quality, reliability and affordability.

We can customize according to customer's requirements.

■ Advantages of Windows:

•High-precision dimensional control

•Lowest beam deviation

•Excellent environmental durability

•Apply to all kinds of Anti-reflective coating
