Introduction

JJF 1001 "General Terms and Definitions of Measurement", JJF 1032 "Glossary Terms and Definitions of Optical Radiation Measurement", JJF 1059.1 "Measurement and Expression of Measurement Uncertainty" and JJF 1071 "Rules for the Preparation of National Metrology Calibration Specifications" It constitutes the basic series of specifications that support the development of this specification. This specification is the first release. Weak ultraviolet radiation meter calibration specification

1 Scope

This specification applies to the calibration of weak UV radiometers. Weak ultraviolet spectrum ray for measuring weak ultraviolet irradiance For the calibration of the relevant metering performance, refer to this specification.

2 terms

2.1 Irradiance meter irradiancemeter An instrument used to measure irradiance in a range of wavelengths, usually consisting of a probe and a reading unit. They are connected by cables or by wireless communication systems. Probe assembly includes cosine corrector, filter and optoelectronics Converter; the reading unit mainly includes signal processing and display circuits. 2.2 UV Irradiometer UVirradiancemeter An irradiometer used to measure the irradiance of a certain wavelength range in the ultraviolet (100 nm to 400 nm). Since the ultraviolet band is usually divided into UVA (315nm~400nm), UVB (280nm~315nm) and In the three bands of UVC (100nm~280nm), the measurement band of the UV irradiance meter is often limited to one of them. One band, and is called UVA ultraviolet irradiance meter, UVB ultraviolet irradiance meter or UVC ultraviolet irradiance meter, respectively. 2.3 weak ultraviolet radiation meter (highly sensitive) UVirradiancemeter An ultraviolet irradiometer that measures weak ultraviolet radiation. In this specification, as long as the measurement range of the UV irradiator includes (10-3~10) μW/cm2 is regarded as a weak ultraviolet radiation meter. 2.4 Spectral irradiance standard lamp standardlampforspectralirradiance Also known as a spectral radiation standard lamp, it is a special electric light source for storing and transmitting spectral illuminance unit quantity, The illuminants are arranged in a plane or straight line in order to calculate the distance between the illuminants and the illuminated surface.

3 Overview

Weak ultraviolet radiation meter can be used to measure ultraviolet radiation in ultraviolet or mixed radiation sources, in materials, light Source, environment, health and other fields have a wide range of applications, especially in the field of health protection and cultural relics protection against weak UV Irradiation meters (or weak UV spectrometers) are increasingly demanding applications. Like ordinary ultraviolet radiation meter, weak purple The measurement band of the external irradiance meter is also often limited to the corresponding UVA (315nm~400nm), UVB (280nm~ One of 315nm) and UVC (100nm~280nm). In order to make the spectral response range of the weak UV irradiance consistent with these specific wavelength ranges, a certain selection is usually used. Bandpass filters (groups) for matching, and cosine correctors are required to improve their directional characteristics, so weak UV The probe assembly of the irradiance meter generally includes a cosine corrector, a filter (group) and a photodetector (usually optoelectronics) Multiplier tube or photocell with embedded amplifier), as shown in Figure 1.
