Polarization filter

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 […]

Polarized backlight

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 […]
