谱线分析仪/二氧化碳激光光谱分析仪 美国1.1 CO2光谱分析仪介绍
1.1.1 CO2光谱仪的工作原理
CO2激光光谱分析仪采用独的光栅分光镜同时能显示CO2激光所有的激光跃迁。它是由波长和选定的转动谱线同时校准，能够很容易分辨在9.1到11.3 微米之间有可能跃迁的140条谱线。由于红外激光光束撞击在使用UV灯照射的热显影板上的区域会变黑，从而在视觉上将这些跃迁展示出来。该显示屏的响应时间只有1/4秒，使得该设备能够找到CO2激光器所有的转动谱线。
2.1.2 点
• 光谱范围9.1um到11.3um；
• 能分辨过140条转动谱线；
• 其他范围可选；
• 重量轻，方便携带，安装简单
2.1.3 主要应用
• 显示激光波长；
• 显示激光谱线；
2.1.4 注意事项
当激光光束功率密度大于25watts/cm2 时，如果裂缝打开得太大，有可能会损坏热敏屏。所有测试开始时可变裂缝应处于“关”的位置。当激光光束功率密度过低时，在裂缝完全打开的情况下也不能在光束监控器上观察到，这时就需要通过聚焦来提高激光的功率密度。
上图是按实际大小展示的部分波长范围，上面的刻度是转动谱线指示，下面的是微米级的波长刻度，在中间的热敏屏上显示的一条黑色线是激光波长。显示屏较宽的热敏范围可以同时显示多条不同功率密度的谱线。

CO2 Spectrum Analyzer

The CO2 Spectrum Analyzer is a unique grating spectroscope which simultaneously displays all the lasing transactions of a CO2 laser. It is calibrated both in wavelength and rotational line designation to permit easy identification of 140 possible laser transitions between 9.1 and 11.3 µ. These transitions are visually displayed through the use of a UV excited thermal sensitive screen which darkens in the area struck by the IR laser beam.

The spectrum analysis screen has a response time of 1/4 seconds and permits the instrument to resolve all the CO2 rotational lines. The Model 16-A is light, portable and can easily be introduced into laboratory setups.

Wavelength Scale

This is a portion of the wavelength scale shown at full size. The upper calibrations are CO2 rotational line designations and the lower scale is the wavelength in microns. The thermal sensitive screen in the center displays the lasing wavelengths as a dark line.

The wide sensitivity range of the spectrum analysis screen can simultaneously display lines which differ in power density by a factor of 20. Each instrument is factory calibrated and should never need adjustment. However, a simple procedure allows the calibration to be checked by the user.

During operations, the laser beam is allowed to strike the front of the Spectrum Analyzer so that a portion hat a portion of the beam passes through a variable slit. Normally the laser beam is intense enough that it is not necessary to focus the light on the slit. The light which does not pass through the slit is absorbed in the matte anodized case.

The internal beam monitor is a Thermal Imaging Plate that displays the CO2 laser beam which has passed through the slit. During the positioning of the instrument this device is engaged. When the monitor indicates the Analyzer to be properly positioned, it is then disengaged to allow the beam to pass onto the display screen
