About Optical Diffusers and Apollo Optical Systems
                     About Optical Diffusers and Apollo Optical 
Systems
Optical (or light) diffusers are devices that 
redistribute light into a desired pattern.
For example, a collimated beam can be incident upon a 
diffuser, resulting in emerging light that spans a wide range 
of directions.
The diffusion characteristics can differ between 
devices. Some may have Lambertian characteristics, 
while others have a Gaussian-shaped scattering.

Operation Principle of Optical Diffusers
A diffuser works to angularly redistribute light, either in 
transmission or reflection. Some examples include:
White ceramics or a sandblasted optical surface.
Light transmission through the ground or chemically etched glass 
(frosted glass).
Plastic or glass optics with prismatic features.
The desired performance of an optical diffuser is highly dependent 
on the application. Performance is considered through the spatial 
characteristics of outgoing light.

Applications of Optical Diffusers
Optical diffusers have a wide range of 
applications for both household and industrial 
use.3 These include:
Integrating spheres: In optical metrology, an 
integrating sphere has a high-quality diffusive 
coating that uniformly scatters incoming light 
with the minimum amount of absorption.

Screens and displays: Screens and displays for 
devices need high scattering (diffusing) light to work 
correctly. This is especially true of laser projectors, 
which need diffusive properties for high-quality images.
Illumination: Diffuse light is desirable for illumination 
and provides uniform light intensity. This is typical of 
street lights, which must give excellent light intensity 
along with high uniformity. Other examples include 
interior lighting and LED illuminators.
