Visible ray optical filtering portion 402 is used to pass through visible ray, and filters out the light of its all band.Infrared light optical filtering portion 404
For by infrared light, and filter out the light of its all band.
When optical filter 10 is in visible mode, actuator 500 drives visible ray optical filtering portion 402 to turn to image sensing
In light path between device 200 and optical filter 10, specifically, mounting hole 22 is blocked in now visible ray optical filtering portion 402.Work as optical filter
10 when being in infrared optical mode, and actuator 500 drives infrared light optical filtering portion 404 to turn to imaging sensor 200 and optical filter 10
Between light path on, specifically, mounting hole 22 is blocked in now infrared light optical filtering portion 404.Referring to Fig. 7, in the embodiment of the present invention
In, it is seen that the angle α between light optical filtering portion 402 and infrared light optical filtering portion 404 is more than or equal to 90 degree.So that proper visible ray filter
When mounting hole 22 is blocked in light portion 402 completely, the completely open mounting hole 22 in infrared light optical filtering portion 404, similarly, when infrared light optical filtering portion
404 when blocking mounting hole 22 completely, it is seen that the completely open mounting hole 22 in light optical filtering portion 402.
