Product Description

Yutai Optics produce optical windows,material have glass series,infrared series,sapphire series,such as BK7, K9, B270, SF6, Fused Silica, ZnSe, Caf2, Ge etc. The shape as round, square, rectangular, customer shape, make hole is also available.

 

Optical Windows are flat, optically transparent plates that are typically designed to maximize transmission in a specified wavelength range,

while minimizing reflection and absorption. They are often used to protect optical systems and electronic sensors from an outside environment.

Because windows introduce no optical power into a system, windows should be selected based on the material transmission properties,

optical surface specifications, and the mechanical properties that match your application.

Material Properties

Material properties including the transmission, refractive index, and hardness of the window substrate can be critical for deciding which window

is the best choice for your application. The figure below highlights the transmission regions of the different materials Yutai Optics offers as
