Introduction

This specification is based on JJF 1001-2011 "General Measurement Terms and Definitions", JJF 1032-2005 "Optical Radiometer Quantitative Terms and Definitions" and JJF 1059.1-2012 "Measurement Uncertainty Evaluation and Expression" together form the supporting book Basic series of norms written by the norms. This specification is the first release. Calibration Specification of Deuterium Lamp Spectral Radiance (250nm~400nm)

1 Scope

This specification is applicable to the calibration of the spectral radiance of deuterium lamps in the wavelength range of (250nm~400nm).

2 Reference documents

This specification refers to the following documents. JJG383 Spectral radiance standard lamp For dated reference documents, only the dated version applies to this specification; for those without date references The latest version (including all amendments) is applicable to this specification.

3 Overview

The deuterium lamp is a gas discharge lamp. The deuterium lamp is classified according to the form of the window and can be divided into end window type deuterium lamp and side window type deuterium lamp. Two kinds. Although each deuterium lamp is different due to different requirements and processing technology, its basic structure and properties Are the same. Because the radiation emitted by the deuterium lamp is mainly concentrated in the ultraviolet band, and has high stability, good reproducibility and longevity The advantages of long life, small size and convenient use make it a commonly used standard radiance transfer standard light in the ultraviolet band source. Figure 1 is a schematic diagram of the structure of the deuterium lamp in two window forms. (a) End window type deuterium lamp Figure 1 Schematic diagram of deuterium lamp structure ......
