Ultra-Wide 124° Field of View
With a 3.6mm focal length and up to 124° field of view, this M12 wide-angle lens captures a broad scene from a compact camera system. The wide-angle design is suitable for applications that require extensive area coverage, including surveillance, robotics navigation, embedded vision and smart devices.
F1.8 Large Aperture for Low-Light Imaging
The F1.8 aperture allows more light to reach the image sensor, helping maintain clear and usable images in relatively low-light environments. This makes the lens suitable for indoor monitoring, security cameras and other vision systems operating under changing illumination.
3MP Resolution for Embedded Vision Systems
Designed for 3MP imaging applications, the lens provides a practical balance between image detail, compact optical design and system cost. It is suitable for cameras using 1/2.5″ sensors and other embedded imaging platforms with compatible optical requirements.
Compact M12×0.5 Mount
The standard M12×0.5 mount provides a compact and lightweight integration solution for board cameras and embedded vision systems. Its small mechanical footprint makes it easy to integrate into space-constrained camera housings and intelligent devices.
Close-Focus Capability
With a minimum object distance of 0.1m, the lens can capture subjects at relatively short distances. This provides greater flexibility for compact inspection, monitoring and embedded camera applications where the camera is installed close to the target.
Smart Security & Surveillance
The wide 124° field of view helps security cameras cover a large area with a compact camera configuration. The F1.8 aperture also supports image capture in indoor and relatively low-light environments.
Robotics Vision
The wide-angle optical design can help mobile robots and embedded robotic cameras perceive a larger surrounding area. Its compact M12 mount is suitable for space-constrained AGV, AMR and robotic vision systems.
Embedded Machine Vision
The 3MP resolution, compact M12×0.5 mount and wide field of view make this lens suitable for embedded machine vision systems, intelligent cameras and compact inspection equipment.
Smart Devices and IoT Cameras
The small M12 form factor allows the lens to be integrated into compact camera modules and intelligent imaging devices where space, viewing coverage and optical performance need to be balanced.
Indoor Monitoring
The combination of 124° FOV and F1.8 aperture is suitable for indoor monitoring applications that require broad scene coverage, including offices, retail environments, equipment areas and other compact surveillance systems.
