Lighting types
LED lighting is the most common type of lighting.
Depending on the problem, halogen bulbs, fluorescent light, cold light sources (metal halide light sources with glass fiber light guides) or xenon flash lamps are also used. Although fluorescent lamps (with HF ballast) are inexpensive, they are rarely used because they age quickly (service life approx. 10,000 h) and have to warm up.
Lasers are particularly suitable for structured lighting due to their excellent focus. A typical application is laser lines, which allow part geometries to be checked even if there is no gray value contrast.
