Embodiment 1

[0042] Such as figure 1 , figure 2 and image 3 As shown, an exemplary embodiment of the present invention proposes an optical element 100, the optical element 100 includes a lens 10 and an outer peripheral surface 21 surrounding the axis of the lens 10, the lens 10 includes a light incident surface 11 and a light exit surface 12, and the outer peripheral surface 21 The lens 10 is connected, and a first adjustment structure is arranged axially on the outer peripheral surface 21, and the first adjustment structure can be connected to the light blocking member 200 and can move axially relative to the light blocking member 200, so that the light incident surface 11 can be moved to be stored in the In the light blocking member 200 , further controlling the range of light entering the light incident surface 11 , the detection range of the detector 400 can also be controlled.

[0043] In the embodiment of the present invention, the lens 10 , the outer peripheral surface 21 and th...

Embodiment 2

[0054] combine figure 2 , image 3 and Figure 4 , an exemplary embodiment of the present invention proposes a detector 400, which has the optical element 100 as in Embodiment 1, the light blocking member 200 capable of socketing the optical element 100, and the light-sensitive position arranged on the optical element 100 photosensitive element 300 . The light blocking member 200 can block the detection light of the detector 400 . For example, when the detector 400 is an infrared detector, the light blocking member 200 should be able to block infrared rays. The optical element 100 has an outer peripheral surface 21 , and the light blocking member 200 can be sleeved on the outer peripheral surface 21 . The light blocking member 200 has a light blocking part and a matching part arranged in sequence along the axial direction. Under the action of an external force, the light blocking part 200 can move relative to the optical element 100 along the axis and make the matching pa...

Abstract

The invention discloses an optical element and a detector. The optical element comprises a lens and a peripheral surface surrounding the axis of the lens, wherein the peripheral surface is connected with the lens; and a first adjusting structure is arranged on the peripheral surface along the axial direction, can be connected with a light blocking element and can axially move relative to the lightblocking element, so that a light inlet surface can move to be collected into the light blocking element, thereby controlling the range of light entering the light inlet surface, namely controlling the detection range of the detector. Compared with the prior art, the optical element disclosed by the invention has the advantages that the peripheral surface and the first adjusting structure are integrally arranged, so that the light blocking element used for adjusting the field range can be directly arranged on the optical element, and the target of adjustable field range is achieved when external force directly acts on the light blocking element connected to the optical element, thereby adjusting the distance between the light blocking element and a detection lens without arranging a special adjusting mechanism for the light blocking element, and achieving the target of adjustable detection range of the detector on the basis of not greatly increasing the installation space.

Description

technical field [0001] The invention relates to the technical field of detection, in particular to an optical element and a sensor. Background technique [0002] Detectors have been widely used in the security alarm industry. In different scenes, it is often required that each detector has a different field of view. [0003] In order to make the field of view range of the detector adjustable, a field of view adjusting device can be configured for the detector. However, the adjustment device in the related art usually has a complex structure, which requires a large-volume adjustment mechanism to connect the sleeve to drive the sleeve to move relative to the detection lens, thus greatly increasing the space required for installing the detector. Contents of the invention [0004] In order to realize the adjustable detection range of the detector without greatly increasing the required space for installing the detector, the invention provides an optical element and a detecto...
