As one of the most professional optical windows manufacturers, AT Optical specializes in processing all kinds of optical window/flat, mainly used for all kinds of optical system protection sheet, based on optical glass, quartz glass, infrared materials, etc., at the same time, various kinds of coating can be performed on the surface. Such as AR coating, Mirror coating, Filter coating and so on.

Types of laser optics windows/Flats

Standard Windows

optical glass window – High-transparency precision diamond optical window for research, industrial, and laser systems. Excellent clarity & durability. Custom sizes available!

Brewster Windows

Brewster windows are primarily employed in laser cavities to generate beams with high polarization purity. When unpolarized light strikes an uncoated substrate at Brewster's angle, the reflected component becomes completely S-polarized while the transmitted portion remains partially P-polarized.

Comparing Optical Flat and Sperical Surface

The optical flat surface is flat and has no curvature, and light does not refract as it passes through. It is suitable for occasions where the shape of the lens is required to be high.

‌The spherical surfaces are curved and have a certain curvature that refracts light as it passes through, helping to adjust the focus of light.

As a trustworthy and reliable optics manufacturing company, we provide you with Optical laser lens.
