Overview

‌Full spectrum solar simulator‌It is a device that can simulate solar light sources and is mainly used to test the performance of optoelectronic products under different spectra. It can emit a spectrum similar to sunlight, including visible and infrared light, and even simulate the solar spectrum under different seasons, latitudes, and weather conditions, providing a more realistic testing environment‌.

Working principle and application scenarios

By using high-precision light sources such as xenon lampsLEDA lamp or laser and a spectral modulator are used to precisely control the wavelength and intensity of light to simulate the solar spectrum at different times and locations. This device is widely used in various fields such as material aging testing, automotive interior and exterior aging testing, vehicle thermal management sunlight simulation testing, solar cell characteristic testing, optoelectronic material characteristic testing, etc.

Technical parameters and performance indicators

The key technical parameters include:

1)‌spectral range‌Usually covered300Nano to2500The full spectrum range of nanoscale solar radiation.

2)‌light intensity‌: The light intensity can be adjusted to simulate different solar radiation conditions, in watts/Square meters（W/m²）.

3)‌light source‌Xenon lamps or metal halide lamps are commonly used, as these light sources have a spectral distribution closer to that of sunlight.

4)‌irradiation angle‌The irradiation angle can be adjusted to simulate different solar zenith angles and incident angles.

5)‌uniformity‌Has good beam uniformity, ensuring that the measured equipment can receive uniform illumination.

6)‌stability‌Has high stability, ensuring consistent simulation of solar parameters.
