Abstract: A heating device for a lens, and an optical camera and a method for manufacturing same. A lens (1000) comprises a lens body, the lens body has a first surface (1100) and a second surface (1200) which are opposite to each other, and an edge (1300) that connects the first surface (1100) and the second surface (1200). The 5 heating device (1400) comprises: a heating unit adapted to be arranged on the edge (1300) of the lens body and used for transferring heat to the lens body after being powered. The heating device (1400) can achieve at least one of the beneficial effects such as a simple structure, high heat efficiency, uniform heating, safety in use, and strong weather resistance.

Abstract: The present disclosure provides an optical lens and a manufacturing method thereof, wherein the optical lens comprises: a lens barrel and at least one lens sheet fixed in the lens barrel, wherein the lens sheet on the most object side is overlapped by the lens barrel on a side surface and an upper surface of the lens sheet, wherein the lens barrel comprises a main body and an edge fastener, and wherein the edge fastener integrally extends from the main body and overlaps the lens sheet on the most object side, so that the lens sheet is smoothly wrapped and fixed to the lens barrel. In the case where the stability of the lens sheet on the most object side is ensured, excessive stretching and bending and excessive deformation of the lens barrel is avoided at the same time, thereby improving the reliability of the overall structure.
