Multilayer light filter linear motion IR-CUT switch

Abstract

The invention discloses a multilayer light filter linear motion IR-CUT switch, which relates to the technical field of a support device with an objective lens, an additional lens, a light filter cover, a rotary table or the like. The switch comprises a fixation base and a cover plate. The cover plate and the fixation base are fixed to form a cavity structure. Partition plates are fixed in the cavity structure. The cavity structure is divided into more than two switch piece accommodation cavities by the partition plates. More than one switch piece is arranged in each switch piece accommodation cavity. Each switch piece is opposed to an upper light through hole and / or is located on one side of the upper light through hole. Each switch piece is provided with a light filter. When a controller controls a driving device to operate, a transmission device drives a switch piece to move linearly to come to or away from a corresponding light through hole. A plurality of kinds of light filters with the same thickness or different thickness can be loaded in the switch. Various light filters are used alone or at the same time. The multilayer light filter linear motion IR-CUT switch has the advantages of good light filtering effect, excellent imaging quality and simple circuit control.

Description

technical field [0001] The invention relates to the technical field of a supporting device with an objective lens, an additional lens, an optical filter cover or a rotating table, and in particular to a multi-layer optical filter linear motion IR-CUT switcher. Background technique [0002] The IR-CUT switcher refers to a set of filters built in the camera lens group. When the infrared sensor point outside the lens detects the change in the intensity of light, the built-in IR-CUT automatically switches the filter according to the external light. The strength and weakness are automatically switched accordingly, so that the image can achieve the best effect. However, the existing switchers mainly have the following disadvantages: 1) Only a single filter can be used independently; 2) Only a small number and types of filters can be loaded, and the difference in thickness of the filters is small The size of the optical sheet is small; 3) The optical filter can only perform single...
