Industrial fixed focus lens definition:

Industrial fixed focus lens, as the name suggests, is a photographic lens with a fixed focal length used in the industrial field. It plays an important role in industrial monitoring, machine vision, automated inspection and other fields with its high precision, stability and durability. Compared with zoom lenses, fixed-focus lenses usually have higher optical performance and less aberration, so they are more suitable for occasions that require high-precision imaging.

Industrial fixed focus lens classification:

Industrial fixed focus lenses are categorized in various ways, among which categorization based on actual application parameters is a common and practical method. The following is a detailed categorization based on two parameters: pixels and focal length:

Classification according to pixels

① Megapixel lenses: Suitable for occasions that do not require high image resolution, but still need to ensure a certain degree of image clarity and detail performance. These lenses are usually used for general industrial monitoring and inspection tasks.

② five megapixel lens: with the improvement of the pixel, the image quality has been significantly improved, suitable for occasions requiring higher image details, such as the detection of precision parts, product quality control.

③ Multi-megapixel and above lenses: These lenses provide extremely high image resolution and are able to capture more detailed information, and are suitable for occasions with extremely high requirements for image quality, such as high-precision measurement, three-dimensional reconstruction, and so on.

Classification according to focal length

① Short focal length lenses (e.g. 8mm, 12mm): have a wider angle of view and can capture a wider scene. This type of lens is suitable for the need to monitor a wide range of areas, such as large workshops, warehouses monitoring.

② Medium focal length lens (such as 16mm, 20mm, 25mm): moderate angle of view, able to balance the width of the field of view and image magnification. This type of lens is suitable for the need to focus on multiple targets at the same time or medium-distance shooting occasions.

③ Long focal length lenses (e.g., 35mm, 50mm, 75mm and above): With a narrower angle of view and higher magnification, they are able to clearly capture details in the distance. These lenses are suitable for precise measurement occasions, such as precision parts inspection on production lines, long-distance target identification, etc.

There are various ways to categorize industrial fixed focus lenses, and the choice of which type of lens to choose needs to be decided according to the actual application scenarios and needs. In the selection, in addition to considering the pixels and focal length and other parameters, you also need to consider the lens aperture, interface type, installation size and other factors to ensure that the lens is perfectly matched with the camera, the installation environment, etc., so as to achieve the best imaging effect.
