Illumination SourcesIllumination sources are devices that are used to provide light in optical inspection equipment. They are an essential component of many types of optical inspection systems, including microscopes, imaging systems, and metrology instruments. Illumination sources are available in a wide range of styles and configurations, and they can be used to produce a variety of different types of light, including visible, infrared, and ultraviolet light.
The type of illumination source that is used in a particular optical inspection system depends on the specific requirements of the application. Some common illumination sources include light-emitting diodes (LEDs), halogen lamps, and arc lamps. These sources are chosen based on factors such as the wavelength and intensity of the light that they produce, as well as their efficiency and reliability. In many cases, multiple illumination sources may be used in a single optical inspection system to provide different types of light or to control the direction and intensity of the light.
