In the journey of exploring the vast universe, the aerospace industry is confronted with countless challenges, among which the performance verification of spacecraft in the extreme environment of space is of vital importance. The space environment is complex and changeable, especially the lighting conditions, which are completely different from those on the Earth's surface. To ensure the stable operation of spacecraft and their components in the space environment, ground simulation testing has become a key link. The solar simulator of Saifan Optoelectronics, with its outstanding technical performance, plays an indispensable role in the aerospace field, providing solid technical support for the aerospace exploration cause of China and even the world.
Accurately simulate space light to facilitate the verification of material performance
Spacecraft in space are exposed to high-intensity solar radiation, and their materials must have excellent weather resistance and stability. Authoritative research institutions such as the Beijing Institute of Aerospace Metrology and Testing Technology have chosen Saifan Optoelectronics' solar simulators to conduct weather resistance tests on aerospace materials. This device can accurately simulate the lighting environment under different latitudes, seasons and weather conditions. In particular, it can highly restore the AM0 standard spectrum in the space environment, with a spectral matching degree as high as ±0.8%, fully meeting the strict requirements for spectral accuracy in the aerospace field. In the test simulating the strong radiation environment of space, researchers used the Saifan simulator to clearly capture the performance changes of different aerospace materials under long-term light exposure. For instance, after conducting a 1000-hour simulated light test on a certain new type of composite material, it was found that its performance degradation rate was 40% lower than that of traditional materials. This key data provided an important basis for the selection of outer protective materials for the space station. Eventually, this material was applied in the construction of the space station, extending the lifespan of the surface coating of the space station by three times. It greatly ensures the safe operation of the space station in the space environment.
Stable output in harsh environments ensures reliable test data
In addition to complex lighting, the space environment is also accompanied by extreme temperature changes, ranging from an extremely cold -270 ℃ to a high temperature of 120℃. The solar simulator of Saifan Optoelectronics adopts a military-grade casting structure, strictly separating the optical chamber from the mechanical transmission chamber, effectively avoiding the interference of external environmental factors on the optical system. Even within the extreme temperature range of -40 ℃ to 60℃, the equipment can still operate stably, with the light intensity fluctuation firmly controlled within ±0.5% per hour. During the solar cell wing test of spacecraft conducted at the China Academy of Space Technology, the Saifan simulator stably output AM0 spectra for 720 consecutive hours in a low-temperature environment of -40 ℃, providing researchers with a large amount of stable and reliable data. Based on these data, the research team successfully optimized the design of the solar cell wing, increasing its power generation efficiency in the space environment by 18%, providing more sufficient energy support for spacecraft to carry out missions in space.
Customized services to meet the special needs of aerospace
Space missions are characterized by diversity and particularity. Different exploration missions have varying requirements for the performance of spacecraft. Saifan Optoelectronics provides customized solar simulator solutions for the special needs of the aerospace field. In the Mars exploration mission, due to the significant differences in the lighting environment on the Martian surface compared to that on Earth and in low Earth orbit, the Saifan Optoelectronics technology team customized and developed the "AM0 Spectrum + Infrared Enhancement" module to simulate the special lighting characteristics of the Martian atmosphere after filtration. Through this module, the lighting conditions on the surface of Mars were successfully reproduced, helping researchers optimize the solar power supply system of the Mars rover. After numerous tests and improvements, the power generation efficiency of the solar panels on the Mars rover in the low-light environment of Mars has been significantly enhanced, ensuring a stable and reliable energy supply for the Mars exploration mission and taking a solid step forward for the success of China's Mars exploration cause.
The solar simulator of Saifan Optoelectronics, with its precise spectral simulation, stable performance output and strong customized service capabilities, has become an indispensable key equipment in the aerospace field. From manned spaceflight to deep space exploration, from space station construction to satellite development, the technical strength of Saifan Optoelectronics has helped aerospace researchers overcome one technical challenge after another, providing reliable guarantees for the safe operation and mission execution of spacecraft in space. Choosing the solar simulator of Saifan Optoelectronics means choosing to inject powerful "photodynamics" into the aerospace exploration cause, making the steps of human exploration of the universe more solid and powerful.
