TECHNICAL FIELD
[0001] The application relates to the technical field of calibration of ultraviolet radiation illuminometers, in particular to an ultraviolet radiation illuminometer calibration device and an application method. BACKGROUND
[0002] An ultraviolet radiation illuminometer is a professional instrument used to measure the radiation intensity of ultraviolet light. This instrument has applications in multiple fields, such as photochemistry, material aging testing, non-destructive testing, medical disinfection, plant growth lamps, and other fields.
[0003] The working principle of an ultraviolet radiation illuminometer is mainly based on the photoelectric effect. The instrument is usually composed of a photosensitive sensor and a microammeter. When ultraviolet light shines on the photosensitive sensor, a photoelectric effect occurs on the semiconductor material, resulting in a potential difference at the junction of the semiconductor and the metal film. The generated potential difference will generate a current through the external circuit, and the current value can be indicated on the microammeter. By measuring the generated current or voltage, the ultraviolet radiation illuminometer can convert the light signal into an electrical signal and finally display the radiation intensity of the ultraviolet light in digital form.
[0004] Before using an ultraviolet radiation illuminometer, it needs to be calibrated first. The equipment needed during calibration includes a light shielding box, an ultraviolet radiation source, a to-be-detected ultraviolet radiation illuminometer, and an ultraviolet radiation illuminometer standard. During calibration, the ultraviolet radiation source, the to-be-detected ultraviolet radiation illuminometer, and the ultraviolet radiation illuminometer standard are all set inside the light shielding box. Then, the ultraviolet radiation illuminometer is turned on and preheated for 30 minutes. Then, the to-be-detected ultraviolet radiation illuminometer and the ultraviolet radiation illuminometer standard are used in turn to measure the ultraviolet irradiance of the ultraviolet radiation source at different distances. The above measurement process is repeated at least three times, and the to-be-detected ultraviolet radiation illuminometer is calibrated according to the measurement results of the to-be-detected ultraviolet radiation illuminometer and the ultraviolet radiation illuminometer standard.
[0005] However, in the related art, during the calibration of the ultraviolet radiation illuminometer, the ultraviolet radiation source needs to be turned off first, and then the position of the ultraviolet radiation illuminometer standard or the ultraviolet radiation illuminometer needs to be replaced or adjusted. This makes the ultraviolet radiation illuminometer need to be preheated multiple times to complete the calibration of the ultraviolet radiation illuminometer, thereby reducing the efficiency of the calibration of the ultraviolet radiation illuminometer.
