Problems solved by technology

However, the existing infrared filter switch modules are generally made of plastic, which will expand as the room temperature increases.
At this time, the focus of the lens will move forward (Front Focus), the lens will not be able to accurately focus on the image sensor, and the image will become blurred

Abstract

The invention provides an optical filter switcher module integrated with a lens, which includes a housing component and an optical filter switcher. The shell assembly includes a first shell and a second shell. The first shell has a first through hole, and the first through hole extends along the axis. The second shell is arranged in the first shell along the axis and partially embedded in the first shell. The second housing has a second through hole corresponding to the first through hole. The coefficient of thermal expansion of the first housing in the direction along the axis is smaller than the coefficient of thermal expansion of the second housing in the direction along the axis. The filter switcher is configured on the second housing and partly corresponds to the position of the second through hole.

Description

technical field [0001] The invention relates to an optical filter switcher module, in particular to an optical filter switcher module applied to lens integration and integrated with a lens. Background technique [0002] Generally, the filterable lens integration is mainly assembled by the filter switch module and the lens (Lens), and the image sensor (Image Sensor) is arranged on the side of the filter switch module relative to the lens, so that the lens The focal point can be accurately focused on the image sensor, wherein the filter switcher module is, for example, an infrared filter switcher (IR-CutFilter Removable, ICR) module. [0003] With the vigorous development of technology, the resolution of the image sensor has become higher and higher, so the sensitivity of the image sensor to the focus of the lens has also increased. However, generally, the existing infrared filter switch modules are made of plastic, which will expand as the room temperature rises. At this ti...
