Four parameters of industrial camera lens

Jan 31, 2023

Industrial lens is a camera or photographic lens used in the field of industrial automation, which is mainly used for optical imaging.
Industrial lens is an essential core basic hardware in machine vision, which has a key impact on the quality of imaging. It can be divided into fa lens (also known as CCTV lens), zoom lens (both manual and automatic), telecentric lens (generally including object telecentric and double telecentric), etc.

1. Working distance WD: refers to the distance from the lower end of the lens to the object surface.
The space required by the machine vision optical system should not only consider the length of the camera lens group itself, but also leave the working distance of the lens. If the space cannot meet the sum of the two, we should immediately consider changing the working direction of the prism or customizing the optical system.

2. Focal length: the distance from the lens to the imaging surface.

3. Depth of field DOF: the depth range that the lens can see clearly.

The relationship between depth of field and focal length is: the longer the focal length, the smaller the depth of field; The shorter the focal length, the greater the depth of field.
The relationship between the depth of field and the working distance is that the shorter the working distance, the closer the lens is to the object, the smaller the depth of field, and vice versa.
4. FOV: refers to the maximum range that the lens can see. Simply put, it is the area where the lens can normally detect.
