Light Diffusers soften the intensity of light and disperses the light over a wider output area. While light efficiency is lost, diffusion helps reduce hot-spots and helps provide a softer evenly illuminated field of view as opposed to a more focused light source. Machine Vision Direct can customize many of our lights to come diffused from the factory so that external diffusers are not required. If there are ever any questions in regards to which diffuser is right for you, contact our applications team at (800) 834-5588 for assistance in choosing the right diffuser for your use case.
