Каковы основные параметры объектива М12? Каковы области его применения?

The M12 lens is a popular modular lens, especially in security monitoring equipment, it is one of the most common supporting lenses. The M12 lens can be used in different monitoring environments and has a wide range of applicability.

1、What are the main parameters of the M12 lens?

Вообще говоря, M12 lenses have different lens model requirements depending on the specific application, and the focus on parameters may also be different. The following introduces several common M12 lens parameters:

Фокружная длина

Focal length is usually measured in millimeters (мм), такие как 2.8 мм, 3.6 мм, так далее. Different focal lengths determine the field of view and magnification of the lens.

Поле зрения

The field of view angle indicates the field of view of the lens, usually expressed in degrees of horizontal, vertical or diagonal field of view angle, такие как 110 градусов, 80 градусов, так далее.

Разрешение

Resolution refers to the maximum resolution that the lens can achieve, usually expressed as the number of pixels corresponding to the horizontal line, such as 1920×1080, 2560×1440, так далее.

Диафрагма

Aperture represents the maximum aperture value of the lens, which determines the light transmittance of the lens. Common aperture values include F1.8, F2.0, F2.8, F4.0, так далее.

Размер датчика изображения

This is commonly referred to as the target surface size, which indicates the size of the image sensor that the lens is suitable for, такие как 1/2.5 дюйм, 1/3 дюйм, так далее.

Искажение

Distortion refers to the degree of distortion of the lens image, such as fisheye distortion, radial distortion, так далее.

2、What are the application fields of M12 lenses?

Сmall video camera

Due to its compact design, small size and light weight, M12 lenses can be easily embedded in various small devices. Поэтому, M12 lenses are suitable for various small cameras, such as action cameras, camcorders, дроны, smartphone cameras, так далее.

The application fields of M12 lenses
