[ Instrument R & D of Instrument Network ] As a light source, a solar simulator can be equivalent to a solar light source in a sense, and it can simulate sunlight exposure. Solar simulators are widely used in solar cell characteristic testing, photoelectric material characteristic testing, biochemical related testing, optical catalytic degradation acceleration research, skin cosmetics detection, environmental research, etc.
With the vigorous development of the solar photovoltaic industry, the spectrum matching performance test of solar simulators is becoming more and more important. For most devices that use pulsed xenon lamps as the light source, the ideal test state is to collect the radiation spectrum within a pulse period, and then determine the spectral level of the solar simulator.
It is reported that the SRMO1 Spectroradiometer is developed by the Fujian Provincial Metrology Research Institute / National Photovoltaic Industry Metrology Test Center for the measurement of spectral irradiance of various continuous radiation light sources and pulsed solar simulators. This spectroradiometer has a very high quantum efficiency in the ultraviolet region (250 ~ 350) mm and near infrared region (800 ~ 1700) nm, and also has a high signal-to-noise ratio and a large dynamic range, which can achieve high accuracy and high Stable radiation spectrum illuminance measurement, using a unique technology of high-speed multi-function probe, real-time monitoring of pulsed light intensity changes.
It can be used in the fields of UV lamp radiation measurement, ultraviolet aging test spectral irradiance measurement analysis, solar simulator spectral irradiance matching degree measurement, solar tanning instrument radiation measurement, radiation light source spectral characteristic analysis and lamp spectral radiation measurement. The SRMO1 spectroradiometer has an integrated design of a multi-function radiation probe, which contains a cosine scatterer and high-speed photosensitive device, triggering and spectrum measurement are synchronized, and the same surface is sensitive; it is integrated and fixedly connected with a 2.5m UV-resistant optical fiber to improve measurement accuracy and Stability; high-speed sampling, real-time monitoring of the intensity change characteristics of the pulsed light, the software automatically gives the optimal test conditions, and can simultaneously output the spectral irradiance data and the pulse light relative intensity change curve with time.
In addition, the SRM01 spectroradiometer is designed according to IEC 60904-9: 2007 and IEC 60904-9: Ed.3 (Draft) for the radiation measurement of solar simulator spectral matching degree, the measurement range covers (250 ~ 1700) nm, It is suitable for measuring the spectral characteristics of continuous and pulse type (single strobe or high frequency short pulse width) solar simulators. It can achieve ultra-high-speed measurement of up to 1000 spectra per second, and can capture the spectral intensity and light pulse flat period at different time points within a pulse period, and automatically return the spectral radiance measurement results of the light pulse flat period to avoid the rising edge of the light pulse Or the falling edge affects the measurement.
Radiometer
Radiometers are divided into portable radiometers, multi-function radiometers, integrated radiometers, split radiometers, long rod radiometers and so on. In order to better bring convenience to users, more and more styles of radiometers are available. Radiation instrument is a general term for instruments and devices that detect ionizing radiation and have functions of identification and measurement. It is used to detect radioactive contamination, measure the γ dose rate in the contaminated area, measure the surface radioactivity of the human body, equipment and various objects, and roughly determine the specific activity of grains, vegetables and water. The radiometer is specially designed for nuclear medicine, molecular biology laboratory, nuclear material transportation, and other areas where α, β surface contamination and χ, γ radiation exist, according to the technical requirements of nuclear rapid emergency response monitoring. It is a highly sensitive intelligence Portable multifunctional instrument.
