VCSEL (Vertical-Cavity Surface-Emitting Laser) devices, with advantages in beam angle and shape, as well as lower threshold current and higher bandwidth, are highly suitable for 3D sensing applications.

Driven by demand in smartphone front-facing 3D sensing, face recognition, ARVR spatial positioning, automotive LiDAR, and high-speed optical communication, VCSEL has become one of the fastest-growing categories of infrared light sources. Its advantages—including low threshold current, high efficiency, controllable beam angle, and ease of array integration—have made it the mainstream light source for 3D sensing modules and are continuously driving the expansion of the IR device market. Recent applications also extend to under-display fingerprint recognition, wearable distance sensing, security monitoring, and short-range depth measurement for AIoT devices.

In VCSEL 3D sensing module production, packaging quality is critical to ensuring output power, thermal stability, lifespan, and optical axis consistency. Therefore, manufacturing equipment must provide high-precision alignment, low thermal stress packaging, and fully automated inspection capabilities. We offer a complete VCSEL module automation solution, covering chip sorting,  AOI inspection, high-precision die bonding and placement, VCSEL/DOE/sensing module opto-mechanical assembly, array light field uniformity and brightness testing, as well as electrical and functional testing. This end-to-end solution helps customers establish high-yield, mass-producible 3D sensing module production lines.
