FILTERING UNIT AND APPARATUS

摘要

The present invention discloses a filtering unit, comprising a plurality of filters, a fixing element and a drive controller. The fixing element is located on a body of the apparatus to be employed for fixedly supporting the plurality of filters. The plurality of filters are rotatably located on the fixing element. The drive controller is coupled to the plurality of filters to drive the corresponding filter rotating according to preset instructions to make light emitted by the lamp pass through the corresponding filter and to filter out light of a corresponding wavelength. Therefore, with the drive controller to drive the corresponding filter rotating according to preset instructions to make light emitted by the lamp pass through the corresponding filter and to filter out light of a corresponding wavelength, the replacement of the filters can be achieved without the manual operation.
