M12 Mount Lens | Compatible with NE301
$5.00
Compatible with CamThink NE301, this M12 lens series offers 2.5mm, 3.0mm, and 6.0mm focal length options, optimized for 1/2.7″ image sensors. Ideal for embedded vision and edge AI applications, with easy installation and manual focus adjustment.
Overview
High-performance M12 mount lenses designed for embedded vision and edge AI cameras.
Available in 2.5mm ultra-wide, 3.0mm wide, and 6.0mm telephoto options, covering use cases from full-scene awareness to mid-range detail capture.
All lenses are optimized for 1/2.7″ image sensors, using precision optical glass and mechanically stable lens assemblies to deliver consistent image quality in real-world deployments.
Key Features
Wide Application Coverage
Horizontal FOV from 137° ultra-wide down to 51° telephoto, suitable for indoor monitoring, corridor observation, and long-range detection scenarios.
Optimized for 1/2.7″ Sensors
Designed for mainstream sensors such as SC3235, offering high resolving power with controlled distortion across the frame.
Standard M12 × P0.5 Interface
Fully compatible with the NE301 onboard lens holder, enabling fast lens swapping and easy integration during prototyping or deployment.
Industrial-Grade Optical Design
Precision lens structures (2G3P / 1G3P / 4G) ensure thermal stability, mechanical reliability, and repeatable imaging performance.
Manual Focus Adjustment
Focus can be fine-tuned by rotating the lens, simplifying calibration during installation and system setup.
