Abstract

The invention provides an optical lens group. The optical lens group sequentially comprises a first lens, a second lens, a third lens, a fourth lens, a fifth lens and a sixth lens from a first side toa second side along an optical axis, wherein the optical lens group satisfies a conditional expression that EFL / BFL is greater than or equal to 3.800. The optical lens group has advantages of being small in size, large in field angle, good in thermal stability and capable of enabling light with different wavelengths to pass through and still maintaining good optical quality.

Description

technical field [0001] The invention relates to the field of optics, in particular to an optical lens group. Background technique [0002] In recent years, the application of portable electronic products has become more and more diverse. In addition to camera and video recording, with the development of head-mounted devices, the application of miniaturized projection lenses has gradually increased. The projection lens is a light source that projects an image after passing through an optical lens group. However, the focal plane of the light will be different due to different wavelengths. In addition, different ambient temperatures may also affect the optical quality. The above problems have become challenges for the development of optical lens groups. Contents of the invention [0003] The invention provides an optical lens group, which has the advantages of small size, large viewing angle, good thermal stability, and can maintain good optical quality while allowing light...
