A thermally isolated infrared camera lens

Abstract

The invention relates to a camera, and provides a thermal isolation infrared camera lens with simple structure, low cost, high imaging quality and good sealing performance of the infrared camera, including a transparent cover shell, a transparent cover plate, an infrared lamp board and a lens. Including a heat shield, the transparent cover is sealed with the transparent cover shell, the infrared lamp board is arranged between the transparent cover shell and the lens, and one end of the lens passes through the infrared lamp board and is installed in the transparent cover. In front of the board, the other end of the lens is connected with a heat shield, and the heat shield is provided with a through hole for connecting the lens with the camera body.

Description

technical field [0001] The invention relates to a camera, in particular to a heat-isolated infrared camera lens. Background technique [0002] Traditional infrared cameras usually use infrared detectors to detect the real-time status of the target itself by heating the target itself. The infrared detector itself is very sensitive to heat. For the accuracy of target detection, the interference to the heat of the instrument itself is required to be small, which puts forward higher requirements for the heat insulation design of the instrument structure. refer to figure 1 , the existing infrared camera lens includes a transparent cover shell 1', a transparent cover plate 2', an infrared lamp plate 3' and a lens 4', and the transparent cover plate 2' is arranged on the transparent cover shell 1', and the infrared The lamp board 3' is set between the transparent cover body 1' and the lens 4', the lens 4' partially passes through the infrared lamp board 3' and is arranged in fro...

Problems solved by technology

However, this structure has poor airtightness, and the infrared detector on the infrared light board is easily affected by the outside world. When the camera is used for a long time, the infrared detector on the infrared light board is easily interfered by the heat of the camera body itself, which makes the image quality poor. High; making existing infrared cameras unable to meet the aforementioned requirements

Although there are some infrared cameras with high imaging quality in the existing market, their structures are complex and the cost is high, so there is an urgent need to develop an infrared camera lens with simple structure, low cost, and excellent performance to meet market demand.
