Product Overview
Compact telephoto lens optimized for HD imaging, suitable for day/night applications with 1/3″ sensors.
The Sunex DSL208A-650-F4.0 telephoto lens is engineered to provide superior HD imaging for applications requiring high precision and clarity. This miniature lens is optimized for use with HD imagers up to 1/3" format, making it suitable for systems requiring compact and efficient imaging solutions. With an effective focal length (EFL) of 15.8 mm and an F/4.0 aperture, this lens delivers crisp images in both daylight and low-light environments. The IR cut-off filter at 650nm ensures that infrared light is effectively blocked, enabling true color reproduction during daylight operation. This day/night optimized lens is ideal for surveillance, industrial monitoring, and other applications where consistent performance is critical. Its M12 mount, fixed focal length, and low distortion (2%) make it a robust choice for long-term use in a variety of environments.
