When selecting a machine vision lens , it is critical not to overlook its importance in the overall system. For example, failure to consider environmental factors may result in suboptimal lens performance and potential damage to the lens; failure to consider resolution and image quality requirements may result in inadequate image capture and analysis. 1 、 I gnoring the importance of the lens in the system A common mistake to avoid when selecting machine vision lenses is to overlook how important the lens is in the system. Here are three key reasons why lenses are critical in machine vision applications: (1) Best image quality The lens plays a vital role in capturing high-quality images. It determines factors such as resolution, distortion, and color accuracy. Choosing the right lens ensures that the system can accurately analyze images and make precise decisions. (2) Proper field of view The lens determines the field of view, which is the area that the camera can capture. It is essenti...

Scan of Chuang A n low-distortion lens tooth model For application scenarios such as medical imaging and industrial testing that require accurate and realistic images, Chuang A n's low distortion lens plays its due role, making the captured images more realistic and detailed, meeting users' needs for image clarity and accuracy. In the field of stomatology, the high-definition images of...

The wide-angle lens is one of the favorite types of lenses for photographers. Its characteristics determine that it can capture more images within a limited distance and is suitable for shooting in many scenes. 1 、 Typical functions  of wide-angle lens in photography (1) Emphasize perspective effect In photos taken with a wide-angle lens, close objects appear larger, while distant objects appear smaller, creating a strong sense of perspective. (2) Expand horizons A wide-angle lens can capture a wider scene than the human eye, incorporating more elements into the picture, allowing the photo to present more environmental information. Wide-angle lens shooting scene (3) Increase depth of field At the same focal length, a wide-angle lens has a greater depth of field than a telephoto lens. In other words, a wide-angle lens can maintain the clarity of both the foreground and the background, making the entire picture more detailed and three-dimensional. (4) Enhanced shooting stability The...

Choosing the right aberration rate for an industrial lens requires considering multiple factors, such as specific application requirements, measurement accuracy requirements, cost budget, etc. Here are some suggestions and considerations for selection: 1. Identify application requirements Identify the specific requirements of industrial applications for image quality and measurement accuracy, and determine the required image quality standards based on the requirements. For example, for some applications that require high image clarity and accuracy, it may be necessary to select an industrial lens with a lower aberration rate. 2. Understanding a berration t ypes Understand the impact of different aberration rates on image quality, including distortion, chromatic aberration, spot spread, etc., so as to choose the most suitable industrial lens for specific applications. Aberrations are mainly divided into radial aberrations and tangential aberrations. Radial aberrations are usually chara...

As the name suggests, a super telephoto lens is a lens with an ultra-long focal length. Compared with conventional lenses, super telephoto lenses can help photographers capture clear and detailed images even when they are far away from the subject. They are mainly used in situations where objects need to be captured at a large distance, such as wildlife photography, sports event   photography, etc. 1 、 Main features of super telephoto lenses The main features of super telephoto lenses include the following: Long focal length The focal length of a super telephoto lens is usually above 200mm, and some can even reach 500mm, 600mm or higher, allowing users to capture clear images even when they are far away from the target. Shallow depth of field, blurred background Because the depth of field is extremely shallow, the background blur effect of the super telephoto lens is very good, which can highlight the subject and make the picture more three-dimensional and visually impactful. This...

1 、 Can a fixed focus lens be used to shoot landscapes? Fixed   focus lenses , that is, lenses with a fixed focal length, are widely used in photography and are loved by many photographers. Although fixed-focus lenses have a limited shooting range, they can also play a unique advantage when shooting landscapes, bringing clearer, deeper, and more creative landscape photos. This is mainly because: (1) Fixed focus lenses have larger apertures Because of their larger aperture, fixed-focus lenses can capture clearer images in low-light conditions and achieve better depth of field effects, highlighting the subject and blurring the background. (2) Fixed focus lenses have higher image quality Fixed focus lenses are generally of higher optical quality, producing clearer, sharper, and more detailed images. This is very important when it comes to capturing fine landscape details. (3) Fixed focus lenses enable free composition Since the focal length is fixed, using a prime lens requires more c...

A line scan lens is a lens specifically used to continuously photograph the surface of an object being measured from one direction. It is usually used in conjunction with a linear array sensor to continuously scan the object being measured by continuous movement or translation to obtain an image of the entire object. 1 、 What are the features of line scan lenses? The main feature of a line scan lens is its ability to capture images of high-speed moving objects. Let’s take a look at its specific features: High-speed imaging Line scan lenses are suitable for high-speed imaging applications and can quickly capture continuous target images. They are suitable for use in industrial inspection, automated production and other fields. Single line scan The design of the line scan lens is suitable for single-line scanning imaging technology, which can scan the target line by line and achieve high-speed imaging. H igh resolution Line scan lenses typically have high resolution, providing clear, d...

1 、 What is pinhole lens? Pinhole lens , as the name implies, is a very small lens, its shooting aperture is only the size of a pinhole, it is the lens used by ultra-micro cameras. Pinhole lenses use the principle of small hole imaging to obtain images and have some unique characteristics and applications. 2 、 What are the characteristics of pinhole lens? As a special camera device component, the pinhole lens has some unique characteristics: (1) Hidden appearance The pores of the pinhole lens are extremely small and similar to the size of the pinhole. Due to the small pore diameter, the size of the entire pinhole camera is extremely compact, usually only the coin size. This small design makes the pinhole camera hide easily in various environments, and it is difficult to be aware of it. (2) Great s cenario i mage Due to the special design of the pinhole lens, its depth of field is very deep and can shoot large -depth images. This means that the objects in front of the camera can be clea...
