About Optical Diffusers and Apollo Optical Systems

The diffusion characteristics can differ between devices. Some may have Lambertian characteristics, while others have a Gaussian-shaped scattering.2 When a diffuser offers Lambertian reflectance, the apparent brightness of the light is the same to the observer, no matter which way they look at it. In Gaussian shaped scattering, or in other angularly tuned distributions, the light can appear brighter or less bright depending on the angle the observer is looking from.
