Overview

IM2200-EM includes all the circuits and software required for high-sensitivity linear image array, optical workbench, and spectroscopic operations. It is a compact and flexible system with expandable interfaces that can be easily integrated into OEM components;

Product Details

IM2200-EM spectroscopy is designed to provide users with applications that require high sensitivity, such as low light, ultraviolet response, and near-infrared response. Electronic circuits are carefully designed to have considerable flexibility and can be connected to various modules and external interfaces. The IM2000 series spectrometer can communicate with PCs, PLCs, and other embedded controllers through USB 2.0, UART, and SPI, where SPI can achieve bus parallel connection for multiple devices. USB connection can provide VCP interface. VCP communication development is simple, cross platform, and does not require installation and development of drivers. Users can operate the spectrometer by sending and receiving serial commands according to our protocol.

Main features:

High sensitivity from ultraviolet to near-infrared, eliminating high-order diffraction interference;

Circuit design with low noise, low power consumption, and resistance to EMI interference;

16 bit high-precision sampling;

Onboard pulse generator, which can be used to trigger other devices;
