Filter (glass plate or foil) from which almost completely linearly polarized light emerges. Polarization filters can be used to avoid reflections. This is usually a rotatable lens filter that suppresses light reflections and ensures a richer color rendition. Disturbing reflections from glass panes, liquid surfaces, shiny metallic materials or smooth, reflective plastic surfaces can thus […]
As with polarized incident light, polarization filters can also be used for backlighting. This can improve the contrast of transparent parts and even make surface tensions visible. For this purpose, a polarization filter is applied to the light plate and a second polarization filter is placed in front of the camera. Depending on the angle […]
