JF-1型X射线晶体分析仪是一种主要利用照相法分析物质微观结构的设备,但在使用该仪器时,经常会遇到如下两个问题:一是分析仪的防护差,散射X射线的剂量大,将给工作人员带来较大的伤害;二是由于通过窗口的X射线束较粗,发散角大,用通常目测X射线在相机荧光屏上产生的亮点来调正相机光路不大准确,难以获得较理想的衍射底片。为了解决上述问题,我们根据激光的亮度高、直观性好、单向性相干性好的优点,研制了一台为该分析仪配套使用的激光准直仪,以准确模拟具体分析 JF-1 X-ray crystal analyzer is a device mainly used to analyze the microscopic structure of the material, but in the use of the instrument, often encounter the following two problems: First, poor protection of the analyzer, scattered X-ray Of the dose, will bring greater harm to staff; second is due to the X-ray beam through the window thicker, divergence angle, with the usual visual X-ray generated in the camera screen to adjust the light path is not large Accurate, it is difficult to obtain the ideal diffraction film. In order to solve the above problems, we have developed a laser collimator for the analyzer based on the advantages of high brightness, good visualization and good unidirectional coherence to accurately simulate the specific analysis
