What are the types of goniophotometer

There are several common goniophotometers for light distribution. The difference between them lies in the geometric shape of the measurement, that is, how to collect photometric data and how to mechanically realize the measurement. The types of Goniophotometers can be basically divided into Type A, Type B and Type C. For a detailed description, please refer to the 1987 edition of CIE 70. The diffe...

What does an integrating sphere measure

Generally speaking, the optical diffuser, when used carefully, can reduce the small errors caused by the uneven distribution of the incident light source on the detector or the deviation of the beam during measurement, so the accuracy of the integrating sphere measurements can be improved. However, in precise measurement, an integrating sphere must be used as an optical diffuser to minimize the ab...

What is an ESD test generator used for

The ESD test generator is mainly used to simulate the static electricity on the human body. The main function is to generate a certain amount of static electricity to see whether electronic related products can maintain normal operation under the action of static electricity. Then why do we do such a simulation esd test? Mainly because ESD test will cause certain harm to electronic components or p...
