Coligh customs and manufactures 940nm VCSEL beam shaper 120°x50° FOV for 3D ToF sensing. They are suitable for compact LiDAR & AGV modules applications. We have standard stock for FOV 50°x35° to 120°x90°. Contact us for more detail.
940nm VCSEL Beam Shaper FOV 120°X50° Product Discription
The 940nm VCSEL beam shaper (FOV 120° x 50°) is specifically designed for high-power, compact 3D ToF camera modules. It precisely shapes the output from a VCSEL array or single-point laser into a rectangular flood illumination pattern with a 120° (horizontal) by 50° (vertical) field of view, featuring highly uniform energy distribution.
940nm VCSEL Beam Shaper FOV 120°X50° Key Features
- In addition to standard 0.45mm or 0.5mm options, we offer a 0.35mm thickness specification; this ultra-thin profile is ideal for wearable devices (such as AR/VR headsets) and miniature industrial scanners.
- This VCSEL beam shaper generates an asymmetric, high-efficiency 120° x 50° light pattern, concentrating energy within a wide horizontal scanning zone—making it suitable for applications such as AGV (Automated Guided Vehicle) navigation, logistics barcode line scanning, and specific facial recognition scenarios.
- All diffusers currently listed on our website are in stock, enabling flexible engineering prototyping and small-batch pilot production.
- Each shipment includes comprehensive spectral test data, FOV energy distribution profiles, and inspection reports, ensuring full batch traceability.

940nm VCSEL Beam Shaper FOV 120°X50° Applications
Industrial AGVs
The core obstacle avoidance requirement for AGVs and service robots such as cleaning/delivery robots lies in the path they travel on. General-purpose large-area diffusers project a large amount of infrared light onto ineffective areas such as the ceiling and overhead. A 120°×50° horizontal light spot can match the contour of the road ahead of the robot, detecting obstacles and extending the effective detection distance of VCSELs.
3D Machine Vision
High-precision vision systems for logistics parcel sorting and industrial contour measurement require extremely uniform illumination sources with no zero-level bright spots. A 940nm VCSEL Beam Shaper linear VCSEL or a single-point multi-junction VCSEL, combined to form a line laser or area array light source, can be installed next to a line scanning camera above the conveyor belt to enhance 3D contour accuracy.
Compact Device Recognition
Smartphones, smart door locks, and payment terminals are extremely sensitive to the thickness of ToF or structured light modules. A thickness of 0.35mm can be directly mounted on top of the VCSEL chip, greatly reducing the Z-axis height of the transmitting module. Furthermore, the 120°×50° light field precisely covers the effective area required for face/palmprint recognition.
