CaF2 Plano-Convex Lenses (PCX4-102)
CaF2 plano-convex lenses are made of calcium fluoride (CaF2) material, have one curved surface and one flat surface, and have a positive focal length. They are very suitable for light collection and focusing in many imaging applications, and can be used as microlenses on top of wafers, or in macroscopic optical systems.

It outputs real‑time spatial coordinates of every vehicle across the full road section around‑the‑clock, delivering a brand‑new sensing technology for vehicle‑road cooperation, smart highway construction and urban traffic management.
VCSEL, short for Vertical Cavity Surface Emitting Laser, is a widely used semiconductor laser component in modern optoelectronics. Unlike traditional edge-emitting lasers, VCSEL emits laser light vertically from its chip surface. Thanks to its low power consumption, stable beam quality, low cost, and easy integration, it has become the core light source for 3D sensing, wearable devices, and high-speed optical communication.
