Environmental testing of optical and photonics instruments

Optical and photonic instruments are widely used in various fields of the national economy and international science and technology. Due to the very complex environmental conditions of their use and transportation, there are influences from various environmental conditions such as physical, chemical, biological, climatic and electrical conditions, which will cause the performance of optical and photonic instruments to change and prevent them from functioning properly.
In view of the above reasons, in order to ensure the quality of optical and photonics instrument products, it is necessary to simulate various complex changes in environmental conditions and conduct tests on optical and photonics instrument products.
The purpose of environmental testing for optical and photonics instruments is to simulate the specimen's ability to withstand harsh climatic, mechanical, biological, electrical (including static electricity) and chemical environments during assembly, storage, transportation and use, and to determine the environmental adaptability of the product.
Zhongke Testing Reliability Experiment Center has environmental testing capabilities for various optical and photonics instruments, and provides professional environmental testing services such as low-temperature testing, high-temperature testing, damp-heat testing, temperature gradient testing, and temperature mutation testing for optical and photonics instrument products.

Optics and photonics are a type of instruments that can generate light waves and display images, or receive light waves and analyze and determine their light properties. There are three main categories:
1. Projection optical instrument
Image (large or small) camera, projector, slide projector, projector, etc. on the screen.
2. Vision aid optical instrument
Helps human eyes observe small objects close up or objects far away, such as magnifying glasses, telescopes, microscopes, etc.
3. Spectroscopic instrument
The frequency of light can be measured directly or indirectly, such as spectrometer, spectrograph, interferometer, etc.

Temperature and humidity test: low temperature test, high temperature test, damp heat test, condensation test, temperature gradient test, temperature mutation test, cyclic damp heat test
Mechanical force test: impact test, collision test, tipping and overturning test, free drop test, bounce test, constant acceleration test, sine vibration test, broadband random vibration test
Comprehensive test: pollution, solar radiation comprehensive test; low temperature, high temperature or temperature change and collision or random vibration comprehensive test; low pressure and low temperature, atmospheric temperature, high temperature or moist heat comprehensive test
Other tests: salt spray test, sand and dust test, dripping rain test, high internal pressure test, low internal pressure test, immersion test, solar radiation test, weathering test, mold growth test, pollution test, wet air test containing sulfur dioxide and hydrogen sulfide
