JSD2120

Description

The industrial lens model JSD2120 is a wide-angle fixed-focus lens. Its core feature is a large 122.2° horizontal field of view (HFOV), which provides broad coverage and makes it highly suitable for monitoring large areas within confined spaces. It employs an F2.0 large aperture design, ensuring good light intake and image brightness even in low-light environments. The lens has an effective focal length (EFL) of 1.88mm and utilizes a hybrid optical structure comprising 2 glass elements and 4 plastic elements (2G4P). This design helps achieve the required optical performance while maintaining cost control. As a wide-angle lens, its distortion is kept within a reasonable range (<-11.02%), typically manifested as barrel distortion, which can be effectively corrected using algorithms in practical applications. This lens is primarily aimed at embedded vision applications that require a large field of view and are cost-sensitive.

Application

Security Monitoring: Its wide field of view is particularly suitable for indoor scenarios requiring coverage of large areas, such as offices, warehouses, and retail stores. A single device can achieve extensive surveillance.Industrial Inspection: On production lines, it can be used for the overview inspection of large-sized products or components, performing tasks such as appearance overview, presence detection, or process monitoring—for example, checking the overall placement or general distribution of products

Smart Terminal and IoT Devices: The compact optical design and wide viewing angle make it an ideal choice for devices like smart home doorbells and video conference cameras, enabling an extremely wide shooting angle within a small form factor
