Features of zoom lenses:
There are two control schemes, one is the kernel control, the other is the external circuit board control.
Core control: No additional hardware is required to control the lens.
External circuit board control: On the basis of controlling the lens autofocus, some parameters can also be modified to improve the autofocus effect, and the additional control board can have more control schemes.
Infrared Zoom Lens Description:
Wavelength: 8-12um
Focus Type: Motorized Adjustable,
Uasge: urban security, highway, railway, forest fire prevention, port, and frontier defense.
Zoom lenses can be classified by focal length, focal length value, aperture and zoom function.
1. Lenses can be classified by focal length, which may vary, and may have features such as automatic or manual aperture.
2, the classification of the lens is divided according to the size of the focal length, such as ordinary, wide Angle, telephoto, etc.
3. Lens zoom mechanism can be manual, electric and other options.
Continuous zoom lens is a high-end custom product. With the popularity of infrared technology, continuous zoom lenses are developing in the direction of high precision, small size, low cost and mass production.
Rising has extensive experience in customizing continuous zoom lenses. We customize different lens control schemes according to customer requirements and add other functions such as temperature compensation. In short, we will continue to improve the function of the product.

FAQ:
Does this lens need a potentiometer?
Potentiometers are used for position feedback, which is crucial for autofocus. So we have to find something that can replace the potentiometer. For example, encoder motors can also save space and improve the aesthetics of the lens, but the cost is higher than the potentiometer, and some magnetic cores are not compatible with the encoder motors, requiring additional control boards.
