Description of Infrared Zoom Lens:
1. Optical system:
Mechanical compensation zoom system: each moving part carries out relatively complex movement according to different movement rules, and finally achieves the purpose of preventing the image surface from moving. Mechanically compensated zoom lenses: One set of lenses (commonly known as the zoom group) makes a linear movement to change the focal length, and the other set of lenses (commonly known as the compensation group) makes a small amount of nonlinear movement to compensate for the displacement of the image plane to achieve the zoom of the optical system. And the position of the image surface must be stable.
2. Optical structure
The optical structure of a mechanically compensated zoom lens is composed of a front fixed group, a zoom group, a compensation group and a rear fixed group.
1, the front fixed group: its role is to provide a fixed image for the system;
2, zoom group: responsible for the zoom function of the system, linear movement to change the focal length;
3, compensation group: according to a certain curve trajectory of nonlinear motion to compensate the zoom group in the zoom process of the image surface movement;
4, post-fixed group: used to convert the image of the compensation group into the final real image of the system, and adjust the synthetic focal length value of the system and the aperture diaphragm of the device to ensure that the system remains unchanged during the relative aperture zoom movement of the compensation group.
