This product is a high-performance InGaAs photodetector in a TO56 package. Its flat-window cap design, combined with a 500μm diameter photosensitive surface, provides excellent sensitivity and reliability for near-infrared optical signal detection.

Large photosensitive surface (500μm)A larger photosensitive area helps improve optical coupling efficiency and reduce alignment requirements, making it particularly suitable for free-space optical communication, weak light signal detection, and multimode fiber coupling applications.

Broad spectrum responseBased on InGaAs material, this detector has a flat and efficient response in the 900nm to 1700nm band (extendable to longer wavelengths), covering key bands for fiber optic communication, lidar and spectral analysis.

High responsivity and low dark currentThe optimized chip design ensures low noise and high-speed response, making it suitable for precision measurement and high-speed optical signal reception.
