Near-infrared (NIR) sensing spans the spectral range from approximately 700 nm to 1400 nm. It is used extensively in applications such as machine vision, biometric authentication, agricultural monitoring, pharmaceutical quality control, and fiber-optic telecommunications. GPD manufactures photodetectors specifically engineered for NIR performance, with optimized responsivity, low dark current, and broad dynamic range. These detectors enable reliable, high-fidelity measurements in both laboratory instruments and rugged field-deployed systems operating across diverse industries and environments.
Silicon detectors lose effectiveness past 1000 nm, right where fiber optics, LiDAR, spectroscopy operate. See why InGaAs photodiodes fill that gap, what separates PIN from APD architectures, and how to choose the right detector for your system.
Introducing our new interactive Photodetector Selector! Engineers can now navigate detector types, key specs, and real-world trade-offs with confidence. From LiDAR to telecom to spectroscopy, find the right photodetector for your application fast.
