Problems solved by technology

At present, the existing optical systems mainly fall into the following two categories: (1) monochromatic light can be generated in a large spectral range, but the power of the light source is small and the light energy output is weak, mainly for optical analysis instruments; (2) the power of the light source is large And it can produce continuous spectrum in a large spectral range, but it is not equipped with a corresponding spectroscopic system and cannot generate monochromatic light
None of these existing technologies can meet the needs of wide-spectrum monochromatic light environment simulation, which has become an important factor limiting the study of biological effects of light environments

The light environment simulation experiment module provided by the invention is composed of a laser pump broadband light source, a high-power xenon light source, monochromators, an optical path transmission system, a module body, an experiment bench, a temperature and humidity control system, and a central analysis control system.

Description

technical field [0001] The invention relates to a light environment simulation experiment chamber, which can simulate watt-level monochromatic light in the ranges of near ultraviolet, visible light and near infrared, and is an experiment chamber for realizing the research on biological effects of light environment. Background technique [0002] With the development of urbanization and electrification, the widespread use of artificial light sources has had long-term and hidden negative effects on human health and ecological security. To explore the biological effects and mechanisms of various light environments, and respond to and intervene in danger, it is necessary to study the biological effects of light pollution on monochromatic light of different wavelengths. At present, the existing optical systems mainly fall into the following two categories: (1) monochromatic light can be generated in a large spectral range, but the power of the light source is small and the light e...
