1. natural light source mode. With natural light illumination, all of the glowing members 400 are turned off, with no means from the laser source.
2. A visible light source mode. Under the condition that the natural light source is insufficient and cannot meet the requirement of inspection, the device provides illumination for the inspection operation by taking the visible light luminous body arranged on the mounting part 200 as an original light source so as to obtain a required image. And the quartz glass with increased surface granularity can be used for light source uniformity to form a visible light band light source.
3. Ultraviolet light source mode. The device forms an ultraviolet light source through the visible light luminophor arranged on the mounting part 200, obtains an approximate radiation state point light source, can provide observation conditions for inspecting defect hidden dangers with fluorescence characteristics, and has higher and more accurate inspection effects on defects which are easy to induce major accidents such as discharging, aging and the like.
