Optical System for Thermal Camera Lens
Optical structure of thermal imaging lenses
The mechanical compensation zoom lens has an optical structure consisting of a front fixed group, a zoom group, a compensation group, and a rear fixed group.
Front fixed group: its role is to provide a fixed image to the system;
Zoom group: It is responsible for the zooming effect of the system, and linear movement to change the focal length;
Compensation group: non-linear motion according to a certain curve trajectory to compensate the image plane movement generated by the variable magnification group during the zooming process;
Rear 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 device aperture stop to ensure that the relative aperture of the system does not change during the zooming motion.
Focusing Mechanism of Infrared Lens
The cam is adjusted.
Focusing with a linear motor.
