Light source, parallel light suitable for Kitozoom, PPL-B

When measuring the diameter of rotationally symmetric parts or the planes of threads and taps, diffuse light can no longer be used, as the light ”creeps” around the edges, resulting in a measured diameter that is smaller than the actual value. Parallel bottom light can be used for such applications, as it ensures that the light comes directly from below, enabling precise measurement. The light from the blue LED (blue = least diffraction) is directed through an optical system with a semi-transparent mirror and passes through a Fresnel lens that emits the light upwards in parallel. The opening for the bottom light is already included in the base plates of the KITO 20, KITO 30, and KITO 40.
