FIELD: measurement equipment. ^ SUBSTANCE: invention refers to analytical instrument engineering. Spectrometre contains casing with entrance gate inside of which optical system is installed at output of which multi-element photodetector is installed connected to electronic unit of control and processing of output signals. Casing is designed leakproof and multi-element photodetector installed in it is designed without casing, at that spectrometre casing is vacuum-treated and/or filled with inert gas. ^ EFFECT: lowering of detection level due to reduction of background radiation. ^ 6 cl, 2 dwg, 3 ex |
