1. An ultraviolet radiation (UVR) imaging system configured to capture images depicting absorption or remittance of UVR, the UVR imaging system comprising:
a camera comprising a monochrome camera sensor;
a radiation source configured to output a UVR waveband;
a filter component configured to differentiate at least one of a UVA waveband and a UVB waveband of the UVR waveband; and
a polarizer component configured to cross polarize each of the UVA waveband and the UVB waveband, wherein the polarizer component has a diameter of between about 10 mm and about 50 mm,
wherein the camera is configured to capture an image depicting an UVA amount of UVA absorption or remittance as projected on a surface area and an UVB amount of UVB absorption or remittance as projected on the surface area.
