Product overview

 The diffuse reflection coating on the inner wall of the standard integral sphere uses a high reflectivity polytetrafluoroethylene material as a whole. The light is reflected in the interior of the integral ball many times. The uniform Lambert surface light source is obtained at the outlet. The high precision and steady voltage DC power supply is used to make it a radiometric calibration with high stability, high uniformity and multi level. Source. The standard radiant source of the integral ball is suitable for the radiometric calibration and other optical measurement applications of various optical sensors in different environments (atmospheric environment and vacuum environment). Have the following characteristics ：

 The inner coating material is made of polytetrafluoroethylene with high reflectivity；

 The luminescence unit adopts high precision current source controlled quartz halogen lamp；

 Wide spectrum range and relatively flat spectrum ；

 Better uniformity of surface and uniformity of angle ；

 Better spectral radiation stability ；

 The outlet height and pitch angle can be adjusted manually or manually；

 The product adopts specially designed aluminum alloy packing box for transport storage protection.
