Photography lenses are typically designed for operating in the human-visible ~420-680nm range. Within this range the lenses have good transmission, and control for chromatic aberrations (e.g. the red, green and blue channels are all in focus). UV photography ideally requires
UV filters
UV photography requires a UV-pass filter (for UV-only photography) and a visible-spectrum-pass filter (also called a UV/IR cut or blocking filter). Photographs are taken with each of these filters using a full-spectrum camera. Available UV filters (empirical imaging has no
Full Spectrum Camera
Camera sensors are developed for recreating images in the human-visible range, however the sensors themselves (CMOS or CCD) are actually typically sensitive down into the relevant UVA range for modelling animal vision (typically about 320nm), and the same sensors are
