Scenario-Based Functional Descriptions
147° Wide Angle FOV for Comprehensive TOF Perception
As a premium Wide angle TOF lens, it boasts a 147° diagonal FOV (120° horizontal, 91° vertical), providing expansive coverage for 3D depth mapping. Unlike narrow-angle TOF lenses that require multiple units to eliminate blind spots, this single Wide angle TOF lens captures a large spatial range in one frame—ideal for AMR navigation, smart home occupancy detection, and industrial workspace scanning. The wide coverage reduces the number of lenses needed for system integration, lowering overall costs while ensuring consistent depth data across the entire sensing area.
F1.3 Large Aperture for Low-Light TOF Sensing Excellence
Equipped with an F1.3 large aperture, this TOF lens outperforms standard F2.0+ TOF lenses by allowing significantly more light intake, ensuring high signal-to-noise ratio (SNR) even in low-light environments (e.g., dimly lit warehouses, evening outdoor scenes). Combined with its 640*480 resolution (5.6μm pixel size), the Wide angle TOF lens delivers sharp depth images and accurate distance measurements, supporting reliable AI-driven object recognition and path planning for robotic systems.
940nm Band Pass Filter & Stable Optics for Reliable Performance
This TOF lens is integrated with a 940nm band pass filter, effectively filtering out ambient light interference and enhancing infrared (IR) signal transmission—critical for high-precision TOF depth sensing. Its fixed iris and manual focus design ensure stable optical performance over long-term use, avoiding focus drift that can compromise depth measurement accuracy. The robust construction (optimized for industrial and consumer applications) makes this Wide angle TOF lens suitable for continuous operation in diverse working conditions.
M12x0.5 Mount & Compact Design for Seamless Integration
Featuring an industry-standard M12x0.5 mount—one of the most versatile interfaces for compact optical modules—this Wide angle TOF lens offers easy integration with a wide range of 3D sensors and camera modules. With a back focal length (B.F.L.) of only 3.4mm and a compact form factor, it is perfectly suited for space-constrained applications, such as small-sized AMRs, smart doorbells, and mini industrial inspection cameras. The lens’s C.R.A. <13.5° ensures compatibility with most mainstream TOF sensors, simplifying system design for manufacturers.
