1000-2600nm Extended Large Photosensitive Surface InGaAs Detector

The C3A-2300LAE series photoelectric detection module integrates photodiodes, amplifier circuits and power conditioning circuits in a miniaturized module. It is 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 supplies. The module contains a linear rectifier circuit to reduce input noise and improve the signal-to-noise ratio. Different types, sizes and speeds of photodiodes are available in the series, such as Si or InGaAs. The typical output characteristics of the module using a 3mm diameter photodiode are ±3V, 0~25MHz (at positive and negative 5V power supplies).

Product features：Compact size、 4 φ6mm through holes for coaxial mounting、 Light-tight and air-tight、 Multiple sensor options、 Switchable 20dB gain、 Wide power input: ±5 to ±20V

Application area：Q-modulated laser monitoring、 Mode-locked laser output monitoring、 Weak visible light detector
