[0023] The present invention will be further described below with specific examples, see figure 2 —4:
[0024] An ultraviolet detector optical subdivision device, including a light source 20, a filter 30, a reflector 40, a concave grating 50, a half mirror 60, a reference photocell 70, a current After the cell 80 and the sample photocell 90, the light of the lamp source 20 sequentially passes through the filter 30, the reflector 40, the concave grating 50, the half mirror 60, and from the half mirror 60 through the reference photocell 70 and It flows through the cell 80 and the sample photocell 90. The groove grating 80 is driven to rotate by the stepping motor 100. The motor shaft 110 is provided with an optocoupler barrier 120 that rotates synchronously with the groove grating 80. One side of 120 is provided with an optocoupler 130 that cooperates with the optocoupler barrier 120, and each time the power is turned on, the optocoupler 130 and the optocoupler barrier 120 coopera...
