Description

Technical Field

[0001] The utility model belongs to the technical field of imaging lens groups, and in particular relates to a common aperture multi-spectral fusion imaging lens group. Background Art

[0002] An imaging lens group, also known as a compound lens, refers to a lens composed of two or more single lenses. A single convex lens can also focus light, but in order to minimize aberration and obtain a balanced and clear image, convex and concave lenses of various forms and various optical glasses must be combined. These concave and convex single lenses are combined individually or glued to form a compound lens suitable for various purposes. Almost 100% of general lenses are compound lenses;

[0003] Conventional long-distance photoelectric monitoring equipment usually uses a continuous zoom lens with a large zoom ratio. In order to ensure the image clarity during the continuous zoom process, multiple lens groups are usually used to correct unfavorable factors such as imaging aberration and chromatic aberration. The large zoom lens used is bulky. Conventional remote photoelectric imaging equipment is usually equipped with two optical lenses with different working modes.

[0004] In "202220342006.7", a common-aperture multi-spectral fusion imaging device is disclosed. Due to the large size of the imaging lens group, it is inconvenient to push the imaging lens group to move when adjusting the angle of the imaging lens group, and the movement angle of the imaging lens group cannot be accurately controlled, making it impossible to align the imaging lens group with the observed object.
