本文介绍了一个直读式光谱分析仪,并对它的电路设计作了比较详细的报导。本仪器具有稳定、准确、快速等优点,适合于合金分析和单色光测定等的应用。波长范围是2000到6000。光学系统的特点在于所接收的同一单色光上可以放置2个(一级)或 4个(二级)测量线。光源激发系统采用和电源频率相同的高压高能火花放电,具有良好的灵敏度。自光电倍增管而下测量系统由脉冲放大、整流、积分和计数器等组成。除装卸样品和记录读数外控制系统的操作全部自动化,同时有高度的保安装置。最后介绍了几个典型的测试数据。
This article describes a direct-reading optical spectrum analyzer, and its circuit design made a more detailed report. The instrument has the advantages of stability, accuracy, speed, etc., suitable for applications such as alloy analysis and monochromatic light determination. The wavelength range is 2000 to 6000. The optical system features two (primary) or four (secondary) measurement lines on the same monochromatic light received. Light source excitation system uses the same high frequency and high power spark discharge, with good sensitivity. Since the PMT down the measurement system consists of pulse amplification, rectification, integral and counter components. In addition to loading and unloading samples and readings, the control system is fully automated and has a high degree of security. Finally, we introduce a few typical test data.
