Optical Diffuser

Optical Diffuser is used to diffuse light evenly in various optical application. It is also used as screens or targets in imaging applications. By spreading incoming light beam evenly across a surface, bright spots can be minimized or removed. The use of different type of substrate will affect the level of loss due to scattering effects.


BK7 is the most common optical glass used in high-quality optical components as it is a hard glass that can withstand a variety of physical and chemical exposure. Relatively scratch and chemical resistant, it has a low bubble and inclusion content, therefore making it an ideal choice for precision lenses. It is the ideal choice for general purpose visual and NIR applications as it has excellent transmission.
