Problems solved by technology

It cannot meet the traceability requirements of low-value radiometers
At the same time, since the ultraviolet radiation of 100nm to 200nm is strongly absorbed in the air, the calibration method stipulated in the "JJG879-2015 Ultraviolet Illuminometer Verification Regulations" is not applicable to the ultraviolet radiation of 100nm to 200nm, resulting in the untraceable source of ultraviolet radiation of 100nm to 200nm

Abstract

The invention relates to a low-value calibration device and method for an ultraviolet irradiance meter. The device comprises an optical platform, three sets of calibration basic units located on the optical platform and a standard ultraviolet irradiance meter. Each set of calibration basic unit comprises an ultraviolet light source, a precision diaphragm, a blind plate, an optical filter group andan attenuation sheet group which are sequentially arranged on the same straight line. The ultraviolet light sources of the three sets of calibration basic units are respectively a first ultraviolet light source positioned at the middle position, a second ultraviolet light source positioned at the rear part and a third ultraviolet light source positioned at the front part; light emitted by the three incoherent ultraviolet light sources passes through the precision diaphragm, the optical filter group and the attenuation sheet group and then is converged at the center of the receiver of the standard ultraviolet irradiance meter, the calibrated ultraviolet irradiance meter is placed behind the attenuation sheet group at the middle position, and the center of the calibrated ultraviolet irradiance meter and the center of the attenuation sheet group are located on the same horizontal line. The device is few in calibration equipment, free of light rails and other equipment, easy to operate, low in cost, small in size and capable of being carried for on-site metering.

Description

technical field [0001] The invention relates to the field of optoelectronic technology, in particular to a low-value calibration device and calibration method for an ultraviolet irradiance meter. Background technique [0002] Ultraviolet detection technology is another dual-use photoelectric detection technology developed after infrared and laser detection technology. Highly sensitive ultraviolet detectors are also widely used in flame sensing, ozone detection, laser detection, fluorescence analysis and astronomical research, etc. Many fields. Ultraviolet irradiance meter is an important instrument for detecting the radiation intensity of ultraviolet light source, which is widely used in ultraviolet detection, medical treatment, epidemic prevention, energy saving and environmental protection, photoelectric reaction and other fields. [0003] The universal ultraviolet band calibration technology in the world uses the low temperature radiometer as the absolute standard detect...
