CH3897AB 1/1.7" 5.7mm 8MP Low Distortion Lens

The CH3897AB lens is designed for smart cities, intelligent security and industrial detection. It has high resolution in the mid-focal length and excellent low-light performance to meet all-weather imaging needs in complex scenes.

CH3897AB has the following product features:

High-resolution imaging: Supports up to 8 million pixels of imaging, can provide clear and detailed images, and meet the needs of high-precision imaging.

Large aperture design: The aperture value is F1.6, which can provide sufficient light intake under low light conditions to ensure the brightness and contrast of the image.

Moderate field of view: The horizontal field of view is 71.3°, which can capture a moderate range of scenes, which can not only meet the needs of wide-angle shooting, but also accurately focus on details, whether it is a wide landscape or a close-up picture, it can be easily controlled.

Adapt to a variety of chip sizes: It can perfectly adapt to sensors with chip sizes such as AR0821, OS04A10, IMX347, IMX586, etc., and is widely compatible with various camera equipment to ensure imaging quality at high resolution.

M12 mount design: It adopts the standard M12 mount, which is small in size and light in weight, and is easy to integrate into various compact devices, such as small surveillance cameras, drones, etc.

Common applications of this lens are as follows:

1. Security monitoring field

In security monitoring scenarios, the CH3897AB low-distortion lens can achieve large-area coverage without blind spots with its wide horizontal field of view of 71.3° and 8-megapixel high-definition configuration. Whether it is public places such as shopping malls and streets, or key protection areas such as banks and warehouses, it can clearly capture the activities of people and details of objects. Its low distortion characteristics ensure that the picture is not distorted, providing accurate and reliable image evidence for subsequent investigations; the f/1.6 large aperture can still ensure bright and clear pictures at night or in dim light environments, effectively identify monitoring targets, and protect safety in all directions. ​

2. Industrial inspection field

Industrial production has extremely high requirements for the accuracy of lenses, and the CH3897AB low-distortion lens perfectly meets this demand. In PCB board inspection, precision parts manufacturing and other links, the 5.7mm focal length and low distortion characteristics can accurately focus on tiny details without distortion and deformation of the picture, ensuring the accuracy of the inspection results. 8-megapixel high-definition imaging can clearly present minor defects such as scratches and flaws on the surface of the product. With the characteristics of being compatible with a variety of chip sizes, it is suitable for different industrial inspection equipment, helping enterprises to achieve efficient and high-precision product quality control. ​

3. Intelligent vehicle field​

In smart vehicle scenarios, the CH3897AB lens plays an important role. Its compact TTL 31.01mm structure and M12 interface design make it easy to install in the car camera, saving space in the car. The wide-angle field of view can cover a large area around the vehicle, and the low-distortion imaging ensures the true restoration of the reversing image and driving record screen, avoiding misjudgment caused by image deformation. The large aperture can still present clear images under complex lighting conditions, such as tunnels and night driving, providing strong protection for driving safety, and also meeting the needs of intelligent driving assistance systems for high-definition and accurate images. ​

4. Machine vision field​

In machine vision applications, the CH3897AB lens, with its advantages of high pixels and low distortion, has become a powerful assistant for tasks such as object recognition, size measurement, and positioning guidance. In the logistics sorting process, it can quickly and accurately identify the barcode and shape of the package; in the automated production line, it can accurately measure the product size and locate the position of the parts, provide clear and reliable visual information for the automated equipment, and improve production efficiency and automation. ​

5. Intelligent transportation field

For intelligent transportation systems, the CH3897AB lens can be installed in traffic cameras for license plate recognition, traffic flow monitoring, etc. The 8-megapixel high-definition imaging can clearly capture the license plate number and vehicle characteristics, and the low-distortion picture ensures the accuracy of data collection; the large aperture design can ensure clear pictures under different weather and lighting conditions, helping the traffic management department to efficiently obtain road information, optimize traffic flow scheduling, and ensure smooth road traffic.
