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 ...
