In industrial production, visual inspection systems play a very important role, and as a key component of the visual inspection system, the performance and applicability of industrial lenses have a direct impact on the accuracy and efficiency of the entire system.There are many different types of industrial lenses, each with its own specific characteristics and usage scenarios. This article will introduce 5 common industrial lens types and their characteristics.
1. Prime lens
A prime lens is a lens with a fixed focal length. The focal length, aperture, imaging size and other parameters of this lens are fixed and cannot be adjusted. The prime lens has the characteristics of simple structure, small size, light weight and low price, and is suitable for detecting specific objects.
2. Zoom lens
A zoom lens is a lens that can change the magnification within a certain range. Users can change the imaging field of view and image size without adjusting the object distance. The zoom lens can meet different inspection needs and achieve high-precision and high-efficiency inspection.
3. Telecentric lens
Telecentric lenses can maintain the magnification of the image within a certain object distance range. This lens can correct the parallax of traditional lenses and improve the clarity and accuracy of the image. It is suitable for detecting objects with high requirements on shape, size, surface, etc., such as optical devices, watches, etc.
4. Bilateral telecentric lens
The design of the bilateral telecentric lens is a dual-port design, which has the characteristics of low distortion, high resolution, and large depth of field. It is suitable for high-precision detection of small and medium-sized objects, such as electronic components, small parts, etc.
5. Line scan lens
Line scan lens is a line scan optical lens that can collect at high speed, has high resolution and low distortion, and can obtain the contour information of objects. It is suitable for rapid and high-precision detection of continuous production lines and large objects, such as products on the production line, large components, etc.
Industrial lenses play a very important role in visual inspection systems. Different industrial lens types have different characteristics and application scenarios. Choosing the appropriate lens can improve the accuracy and efficiency of detection. In practical applications, it is necessary to comprehensively consider multiple factors such as the specific detection object, detection accuracy, and shooting distance to select the most suitable industrial lens.
