Abstract

A Czerny-Turner type spectrometer has been designed and operated as a rapid scanning instrument by placing a rotating mirror near the exit slit. Using a helium-neon gas laser, resolution of 0.027 A has been measured at scanning rates of 0.4 A/microsec. Data have been taken with the scanning rate of 6 A/microsec, which could have been increased an order of magnitude if desired. A scanning range of 1-600 A depending on the grating and mirrors used has been obtained. Applications shown included the shift and shape of xenon spectral lines in a pulsed arc discharge. The associated electronics required for synchronization are included.

摘要

一种 Czerny - Turner 型光谱仪已被设计并通过在出射狭缝附近放置一个旋转镜作为快速扫描仪器运行。使用氦氖气体激光器，在 0.4 Å/微秒的扫描速率下测得分辨率为 0.027 Å。已在 6 Å/微秒的扫描速率下采集数据，如果需要，该速率本可提高一个数量级。根据所使用的光栅和镜子，已获得 1 - 600 Å 的扫描范围。展示的应用包括脉冲电弧放电中氙光谱线的位移和形状。其中包括同步所需的相关电子设备。
