2mm extended large active area InGaAS photodetector module     


This photoelectric detection module integrates photodiodes, amplification circuits, and power conditioning circuits into a miniaturized module. Not only suitable for the construction of various laboratory optical systems, but also suitable for integration in user products. The module is easy to install and can achieve sealing of the optical path. The module can operate with a wide range of positive and negative power sources, and it contains a linear rectification circuit inside the module to reduce input noise and improve signal-to-noise ratio.

Different types, sizes, and speeds of photodiodes are available within the series, such as Si or InGaAs. The typical output characteristics of a module using a 2mm diameter photodiode are ± 3V, 0-25MHz (when powered by ±5V).
