摘要: In a device with replaceable optical filter, a base is provided with a slot and an opening, and middle of the slot has a light-transmitting portion, each of two opposite sides of an inner edge of the slot is provided with at least one protruding portion. An elastic light-filtering member includes an elastic frame body and an optical filter arranged within the elastic frame body and exposed to the light-transmitting portion to filter light. A front end of the elastic frame body is provided with two arc portions, the elastic frame body gradually narrows from its rear end to the front end. Each of two opposite sides of the elastic frame body is provided with one concave portion whose position corresponds to a position of the protruding portion. The present invention directly extracts the optical filter in the slot without repeatedly disassembling the light-controlling device.
