Test Background
The purpose of the low-pressure and high-low-temperature or moist-heat comprehensive test of optical and photonic instruments is to study the degree of change in the optical, thermal, chemical and electrical properties of the sample when affected by low pressure and low temperature, atmospheric temperature, high temperature or moist-heat environment.
Zhongke Testing Reliability Experiment Center has environmental testing capabilities for various optical and photonics instruments, and provides professional environmental testing services such as low pressure, high and low temperature or wet and heat comprehensive testing for optical and photonics instrument products.
Scope of tests
Optical instruments, instruments equipped with optical components and optical components.
