光谱仪的装调装置及方法
摘要：
一种光谱仪的装调装置及方法，包括如下步骤：观察出射聚焦透镜后的光线不同位置处的光斑，固定准直透镜的位置；根据入射狭缝与线阵相机之间的角度关系，将反射镜与衍射光栅以预定角度进行相互固定；将反射镜及衍射光栅以同一轴线转动设置在壳体中，对反射镜及衍射光栅进行转动调节，直至衍射光栅的检测级所对应的衍射光会聚到线阵相机中；进行会聚透镜装调；及确定线阵相机的波长分布曲线。通过准直光线的主要部分经过反射镜后反射至衍射光栅；转动调节反射镜及衍射光栅，衍射光栅的检测级所对应的衍射光会聚到线阵相机中，从而避免了对反射镜及衍射光栅相对入射狭缝或线阵相机的角度进行重复调整，提高光谱仪在装调效率，有效提升光谱仪的产量。
摘要（英）：

The invention relates to a spectrograph adjustment device and method. The method comprises the following steps of observing light spots of a light ray emitting a focusing lens at different positions,and fixing a position of a collimating lens; mutually fixing a reflecting mirror and a diffraction grating according to an angle relation between an entrance slit and a linear array camera; rotatablydisposing the reflecting mirror and the diffraction grating in a shell with the same axis, and rotatably adjusting the reflecting mirror and the diffraction grating until a diffraction light corresponding to a detection level of the diffraction grating is converged into the linear array camera; adjusting a convergent lens; and determining a wavelength distribution curve of the linear array camera.A main part passing through a collimating light is reflected to the diffraction grating through the reflecting mirror, the reflecting mirror and the diffraction grating are rotatably adjusted, the diffraction light corresponding to the detection level of the diffraction grating is converged into the linear array camera, thereby avoiding repeated adjustment of an angle for the reflecting mirror and the diffracting grating relative to the entrance slit or the linear array camera, improving the adjustment efficiency of the spectrograph and effectively increasing the yield of the spectrograph.
