分光计的调节难点、调节方法及其迁移应用

作为一种精密的光学测量仪器,分光计的调节难点是如何调整分光计的中心轴和望远镜的光轴垂直。利用自准直原理,将平行光管狭缝的透射像作为辅助标志物,各半调节、逐次逼近,就可以又快又准地达到调节要求。分光计在结构上与诸多光学仪器有相似之处,掌握其调节方法可以为今后使用精密光学仪器打下基础。

Difficulties and method of adjusting spectrometer

As a precise optical measuring instrument, the spectrometer is difficult to be adjusted to make the center axis of the spectrometer perpendicular to the optical axis of the telescope.By using the self-collimation principle, making the transmission image of the collimator slit as an auxiliary marker, regulating by half and approaching gradually, then we can quickly and accurately meet regulation requirements.The spectrometer has similarities with many optical instruments in structure, so grasping its adjustment method can lay a foundation for the use of precise optical instruments in the future.
