Bright spot light source is the use of high-power LED light source highlights the principles issued by the optical lens after focusing collimated light from the development, compared with traditional halogen lamp brightness constant optical fiber, color uniformity, long life and other characteristics. Top diameter of 8mm, light-emitting surface diameter of 6mm, can be used in machine vision systems alone, but also with the microscope head or telecentric lens with coaxial function to use. Features: 1. High power LED, high brightness, good uniformity 2. small emitting area, compact 3. Efficient heat dissipation, greatly improving life. 4. particularly suitable as a telecentric lens coaxial light source range of applications: 1.MARK point positioning. 2. Suitable for small mounting space vision system. 3. microarray. 4. LCD glass substrate alignment 5. wafer inspection
