WebJun 23, 2024 · Zemax Incoherent Irradiance & SNR As part of a recent illumination project in Zemax, I wanted to integrate a mixing polygon tunnel as part of an aspheric lens. This would have the benefit of: Reducing system complexity, as it would combine two components. Reduce system cost, as both components could be injection molded as a singular system … Webresponse is a function of the input irradiance level. We can only perform LSI analysis for a restricted range of input irradiances. Another linearity consideration is that coherent optical systems (optical processors) are linear in electric field (V/cm), while incoherent systems (imaging systems) are linear in irradiance (W/cm2). We will deal ...
