Optical heating window of camera

Abstract

The invention belongs to the technical field of optical imaging and particularly relates to an optical heating window of a camera. The optical heating window structurally comprises a window body, wherein the window body comprises a first surface and a second surface; the first surface comprises a light transmitting zone located in the center and a heating zone surrounding the light transmitting zone, and a conductive film is arranged on the heating zone and connected with a heating circuit. The technical problems that existing optical windows of cameras have poor defrosting and demisting effects and affect camera imaging easily are solved. The annular conductive film is arranged to heat the optical window of the camera, uniform and quick heating can be realized, the heating effect is good,the window transmittance is high, no effects are caused to optical system imaging, and the heating wire shielding problem is avoided. The window cannot produce stray light such as ghost images understrong light and is particularly applicable to cameras or video cameras working in humid and cold environments.

Description

technical field [0001] The invention belongs to the technical field of optical imaging, and in particular relates to an optical heating window of a camera. Background technique [0002] Heated windows are commonly used as windshields or rear lights in vehicles to enable defogging or defrosting of the windows during cold or wet weather conditions. The optical window for the camera is located at the forefront of the optical path, and is generally a round or square flat plate. In order to prevent the window from fogging and frosting in cold or humid weather and affecting the camera observation, in addition to the defogging and defrosting functions of the window, it is necessary to consider , but also to meet the optical requirements of optical system imaging for window surface accuracy, firmness, and stray light. [0003] Existing camera optical windows usually use active heating methods to defog and defrost. Window heating should not only consider the heating performance, bu...
