Flat Windows
Standard and precision quality laser windows made from high quality UVFS and N-BK7 optical materials. Laser Windows chapter includes uncoated windows with dia from 12.5 to 101.6 mm and thickness from 1 to 15 mm. Also we offer uncoated rectangular windows with aperture from 15 x 20 to 50.8 x 50.8 mm and thickness from 2 to 10 mm. Other specific material, size and anti-reflection (AR) coated windows are available under custom request. Most of the windows are available ex-stock for fast off-the-shelf delivery.
Flat Optical Windows are transparent, flat components used to protect optical systems while allowing light transmission. They are made from various materials such as quartz, silicon, and magnesium fluoride, offering excellent optical clarity and durability. These windows are commonly used in laser systems, imaging applications, and scientific instruments. Custom sizes and coatings are available to meet specific wavelength and performance requirements. High-quality flat windows ensure minimal distortion and high transmission efficiency.
