  As we all know,   industrial lenses   are mainly lenses used in the industrial field. They play an important role in the industrial field and provide important visual support for industrial production and monitoring. Let’s take a look at the specific role of industrial lenses in the industrial field. 1、 The main role of industrial lenses in the industrial field Role 1: Get image data Industrial lenses are mainly used to obtain image data in the industrial field. They can focus the light in the actual scene onto the camera sensor to capture and record images. By appropriately selecting industrial lenses with different parameters such as focal length, field of view, and aperture, the required field of view and image details can be obtained. Role 2: Image analysis and processing Industrial lenses, combined with image processing software, are mainly used to analyze and process images obtained from cameras. They can provide high-quality images with high resolution, low disto...

  The   machine vision lens   is an important imaging component in the machine vision system. Its main function is to focus the light in the scene onto the camera’s photosensitive element to generate an image. Compared with ordinary camera lenses, machine vision lenses usually have some specific features and design considerations to meet the needs of machine vision applications. 1、 Main features of machine vision lenses   1)  Fixed aperture and focal length To maintain image stability and consistency, machine vision lenses usually have fixed apertures and focal lengths. This ensures consistent image quality and size in different scenarios. 2)  High resolution and low distortion Machine vision applications often require high resolution to ensure accurate image analysis and processing. Therefore, machine vision lenses typically feature high resolution and low distortion to ensure image accuracy. 3)  Adapt to different viewing angles Machine vision applic...

Telecentric lenses , also known as tilt-shift lenses or soft-focus lenses, have the most important feature that the internal shape of the lens can deviate from the optical center of the camera. When a normal lens shoots an object, the lens and the film or sensor are on the same plane, while a telecentric lens can rotate or tilt the lens structure so that the optical center of the lens deviates from the center of the sensor or film. 1、 The advantages and disadvantages of telecentric lenses Advantage 1: Depth of field control Telecentric lenses can selectively focus on specific parts of the picture by changing the tilt angle of the lens, thus enabling photographers to create special selective focus effects, such as the Lilliputian effect. Advantage 2: Perspective  c ontrol One of the main advantages of telecentric lenses for architectural photographers is that they provide greater control over perspective. Ordinary lenses may cause straight lines in photography (such as the stacked f...

Machine vision lens   is an industrial camera lens that is specially designed for machine vision systems. Its main function is to project the image of the photographed object onto the camera sensor for automatic image collection, processing and analysis. It is widely used in many fields such as high-precision measurement, automated assembly, non-destructive testing, and robot navigation. 1、 The principle of machine vision lens The principles of machine vision lenses mainly involve optical imaging, geometric optics, physical optics and other fields, including focal length, field of view, aperture and other performance parameters. Next, let’s learn more about the principles of machine vision lenses. 1.Principles of optical imaging. The principle of optical imaging is that the lens focuses light onto the sensor through multiple lens groups (like space lenses and object space lenses) to generate a digital image of the object. The position and spacing of the lens group in the optical pa...
