N-BK7 Plano-Concave Lens (PCV1203)
Plano-concave lenses present one concave surface and one flat surface. They have a negative focal length and are used to reduce images or spread light. These lenses diverge collimated incident light to form a virtual image seen through the lens. They are commonly used to expand light or increase focal length in existing systems.

FiDAR, the fiber‑optic radar vehicle positioning and tracking system developed by Jianhe Bafang, is a high‑sensitivity distributed fiber‑sensing solution designed for intelligent traffic road monitoring. 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.
