drone camera lens

Abstract

The present invention provides an unmanned aerial vehicle camera lens, which sequentially includes: a first lens, a second lens, a third lens, a fourth lens, a fifth lens, a diaphragm, a sixth lens, and a seventh lens from the object side to the imaging surface And the eighth lens, the first lens, the second lens and the fourth lens are meniscus-shaped glass spherical lenses with the concave surface facing the imaging surface, the third lens is a meniscus-shaped glass aspheric lens with the concave surface facing the imaging surface, the fifth The first lens and the sixth lens are double-convex glass spherical lenses, the fifth lens and the fourth lens form a cemented lens, the seventh lens is a meniscus-shaped glass spherical lens with a concave surface facing the object side, and the eighth lens is a double-convex glass aspheric lens . The UAV camera lens in the present invention adopts glass lenses entirely, which can be adapted to different temperature occasions, with good temperature control, clear imaging, high sharpness, and high resolution quality, which can reach at least 12 million or more pixels.

Description

Technical field [0001] The present invention relates to the field of lens technology, in particular to a drone camera lens. Background [0002] With the continuous development of science and technology, in recent years, the rapid development of the UAV industry, UAV is usually used for aerial photography, detective, surveillance, communications, anti-submarine, electronic interference and other occasions, so UAV has become an important tool in civilian, military and other industries. [0003] Among the existing technologies, the camera lenses currently used on the UAV generally have defects such as low resolution quality, difficult processing, poor temperature control, purple fringing phenomenon, etc., which seriously affect the imaging quality of the UAV camera lens, and also become some important factors restricting the development of the UAV, especially due to the poor temperature control of the camera lens, which will lead to a larger impact of temperature on the camera lens,...

Problems solved by technology

[0003] Among the existing technologies, the camera lenses currently used on UAVs generally have defects such as low resolution quality, difficult processing, poor temperature control, and purple fringing, which seriously affect the imaging quality of UAV camera lenses. Some important factors restricting the development of drones, especially due to the poor temperature control of the camera lens, will lead to a greater impact of temperature on the camera lens, making the camera lens unable to adapt to different temperature occasions
