本文对中型石英光谱仪改装为光电直读仪内的光电头的温度补偿机构,作了理论探讨。实验和计算结果表明,该装置能够就±5℃的室温变化对仪器的影响进行补偿。中型石英光电直读光谱仪,在光潜仪的焦面处,装一个内有13个出射狭缝的光电头。出射狭缝检出各待测元素的分析线。因而,当仪器运转时,要求所有
In this paper, the conversion of medium-sized quartz spectrometer into a photoelectric direct reading instrument within the optical head temperature compensation mechanism, made a theoretical discussion. Experimental and computational results show that the device can compensate for the effects of room temperature variations of ± 5 ° C on the instrument. Medium-sized quartz photoelectric direct reading spectrometer, in the submarine photofocus focal plane, equipped with a 13 within the slit of the photoelectric head. The exit slit detects the analytical line of each element under test. Therefore, when the instrument is in operation, all is required
