Bandl S Ring
The Border Ring is also known as a Band-slit ring - a border ring with a hole. The oscillation of light in the hole of the device occurs due to the internal reflection of photons on the edge of the crystal and the emission of a new wave. This circuit has proven to be effective for generating low-o
