Brewster angle

If unpolarized light falls on the interface of two media at the Brewster angle, the reflected light is polarized perpendicular to the plane of incidence. See also Wikipedia

Polarized light that only oscillates in a single direction transverse to its direction of propagation. Principle of polarization of light (source: Vision Doctor). Polarized light can be used to avoid reflections (especially with ring lighting) and to visualize structures in transparent objects. When a surface is illuminated with polarized incident light, all rays reflected by […]

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 […]
