Provided are an infrared optical imaging camera lens and an imaging device. The lens includes sequentially along an optical axis, from an object side to an imaging side: a stop, a first lens having positive focal power, a second lens having positive focal power, a third lens having negative focal power, and an optical filter. An object-side surface of the first lens is a convex surface, and an image-side surface of the first lens is a concave surface. An object-side surface of the second lens is a concave surface, and an image-side surface of the second lens is a convex surface. An object-side surface of the third lens is a convex surface in a region near the optical axis, and an image-side surface of the third lens is a concave surface in the region near the optical axis.

Infrared optical imaging lens, camera module and driving monitor system

The disclosure provides a camera module, a monitoring system and a vehicle camera, the camera module includes a lens barrel, a first lens and a heating element, the lens barrel includes a light entrance, the first lens is disposed at the light entrance, the first lens includes an image side surface, the heating element directly acts on the image side surface to heat the first lens. By directly applying the heating element to the image side surface of the first lens, the heating element can directly transmit heat energy to the first lens, thereby achieving the effect of defogging and defrosting automatically.

Camera module, vehicle camera and monitoring system

The disclosure provides an infrared optical imaging lens, a camera module and a DMS. From an object side to an image side along an optical axis, the infrared optical imaging lens sequentially includes a stop, a first lens with a positive refractive power, a second lens with a positive refractive power, a third lens with a negative refractive power, and a filter. An object side surface of the first lens is convex, an image side surface of the first lens is concave. An object side surface of the second lens is concave, an image side surface of the second lens is convex. A paraxial portion of an object side surface of the third lens is convex, and a paraxial portion of an image side surface of the third lens is concave.
