Convenient UV energy meter calibration clamp and calibration method

Abstract

The invention relates to a convenient UV energy meter calibration clamp and calibration method. Light guide output terminals of two channels of light sources are respectively fixed to a light guide output adjusting end fixing rack, a standard detector and a UV energy meter are respectively fixed to a light fixture base support and a dry plate clamp and move with the same distance, radiation degreeindicating values of the standard detector and the UV energy meter are read and compared, a measuring error or a correction coefficient of the radiation degree under the distance is obtained, a moving distance is changed, and the measuring errors or the correction coefficients required for radiation degrees of different measuring value points are obtained; and in the same moving distance, the radiation time of the light source is changed or the moving distance is changed under the accumulation of the same radiation time of the light source, standard values of the radiation energies of different measuring value points can be calculated through a formula and can be compared with the energy display value of the UV energy meter, and the measuring errors or the correction coefficients of radiation energies of different measuring value points can be obtained. The structure and the operation are simple, the repeatability is good, the applicability is high, and the cost is low.

Description

technical field [0001] The invention relates to a jig for measurement calibration, in particular to a jig for calibrating a convenient UV energy meter and a calibrating method. Background technique [0002] UV (Ultraviloet) energy meter is a high-quality ultraviolet energy counting instrument, which is used to measure the ultraviolet irradiance and radiant energy of different light sources. The usual UV detection method is to measure the peak intensity of the UV light source, which reflects the focusing and attenuation of the UV light source rays, and is used to evaluate the applicability of the light source. With the wide application of UV technology and products, the control of UV radiation dose has attracted more and more attention. The accuracy of radiation dose is related to the processing technology and quality. Due to the particularity of the structure of the broadband measuring instrument and the complexity of the influencing factors, the performance index of the UV...

Problems solved by technology

The disadvantage of the replacement method is that the standard detector and the calibrated detector need to be placed alternately at the required measurement position during the measurement process. Because the sizes of different types of detectors are different, the installation and adjustment errors are relatively large, and human factors cannot be ignored. Both measurement efficiency and accuracy are affected
