Adjustable Illuminance Diffusion Calibration Light Source Produced with Integrating Sphere

The light source used for image intensifier aging characteristic examination must be good color stability, low and adjustable luminous flux, good homogeneity and high creditability diffuse light. A project design is made, mainly including light source and control part. Integrating sphere is adopted in light source design. A special integrating sphere was designed based on theoretical analysis. It's proved that the design can satisfy the technical requirement in theory. A slice machine is the core of control part. The design of control part adopts native control and telecontrol to control the power and temperature of light source. RS232 serial-port is used to realize communication with PC machine. The supervision of the luminous is realized for measurement where image intensifier is placed.
