Uniformity measurements indicate an imaging system’s tendency to become darker away from the center of the image. This is due to the radial nature of the lens which collects more light in the center. It can be particularly strong with wide angle lenses. Testing for uniformity requires a flat-field test, or uniform light source. In order to minimize cosine falloff in imaging systems with wider field of view lenses, it is important to have a light source that produces uniform illumination across the entire field of view. We also provide uniform reflectance targets for use with external light sources.
