Characteristics of anamorphic zoom lenses

The main characteristics of anamorphic zoom lenses include their optical properties, application scenarios, and differences from ordinary zoom lenses.
optical characteristics 
anamorphic zoom lenses have the following characteristics in optical design:
Perspective change: anamorphic zoom lenses can change the focal length and magnification by altering the distance between the internal optical components of the lens. This method can accurately adjust the magnification within a certain range, and during the magnification process, the image plane position is relatively stable, which is conducive to maintaining the clarity and accuracy of the imaging.
Perspective and distortion: Due to its wide viewing angle, wide-angle lenses can capture nearby objects in larger sizes and distant objects in smaller sizes, thereby emphasizing the sense of perspective. When using a wide-angle lens for shooting, barrel deformation is prone to occur, which is more pronounced at the edges of the lens. By adjusting the distance between the lens and the subject, the perspective effect and degree of distortion can be controlled.
Application scenarios
The application of anamorphic zoom lenses in different scenarios is as follows:
Industrial testing: In industrial testing, anamorphic zoom lenses focus more on high-precision magnification change detection of small objects in fixed positions. For example, in the photolithography process of semiconductor chip manufacturing, anamorphic zoom lenses can provide stable magnification changes, meeting the extremely high requirements for microstructure and dimensional accuracy in detection scenarios.
Dynamic tracking: In scenes where a large field of view needs to be covered and objects need to be dynamically tracked, anamorphic zoom lenses perform well. For example, in the monitoring system of an automated warehouse, a anamorphic zoom lens can monitor the entire warehouse's goods from wide-angle mode and adjust the focal length and magnification as needed.
Difference from ordinary zoom lenses
The differences between anamorphic zoom lenses and ordinary zoom lenses are mainly reflected in the following aspects:
Optical structure: Ordinary zoom lenses mainly use multiple movable lens groups to change the focal length of the lens, while anamorphic zoom lenses change the magnification by changing the distance between the internal optical components of the lens.
Magnification variation characteristics: The magnification variation of ordinary zoom lenses is continuous and can achieve any magnification within its focal length range. The magnification variation of anamorphic zoom lenses is usually discrete, with fixed magnification settings, suitable for scenes that require precise magnification control.
