A variety of accessories are available for modifying or upgrading the performance of the systems, including port plugs, port reducers, and uniform source lamps. Uniform source lamps are ideal for many irradiance applications, such as characterizing the responsivity, linearity, photo response non-uniformity, and dynamic range of focal-plan arrays. Additionally, these sources can be used for evenly illuminating test targets for evaluating the CTF of optical systems or imaging lenses, and for measuring cosine⁴ irradiance falloff or other variations in irradiance within optical systems caused by optical aberrations.
