More Information
Summary:An adjustable slit mechanism for a monochromator is provided. The adjustable slit mechanism (81; 300) may be used in a monochromator of a fibre optic atomic absorption spectrometer. The adjustable slit mechanism comprises a first slit member (302) including a first slit edge, a second slit member (304) including a second slit edge, a slit adjusting cam (306) having a variable radius, a first arm (308) connected to the first slit member, and a second arm (310) connected to the second slit member. The first slit edge (312) is arranged opposite the second slit edge (314) to define an adjustable slit of the adjustable slit mechanism. The first arm (308) and the second arm (310) are resiliently biased against the slit-adjusting cam such that rotation of the slit adjusting cam adjustably separates the first arm and the second arm for adjusting a width of the adjustable slit. The invention also provides a slit assembly for a monochromator and a monochromator assembly. 本发明提供了一种用于单色仪的可调狭缝机构。所述可调狭缝机构(81；300)可以在光纤原子吸收光谱
