The IoT Microscopic Interactive Teaching System (based on the Abner ER series microscopes) is an integrated intelligent microscopic teaching solution developed by Aibona Micro-Nano Technology for experimental teaching scenarios in higher education, vocational colleges and middle schools. While supporting traditional microscopic observation, the system integrates functions such as IoT interconnection, real-time interaction, cloud management, image display and teaching analysis, achieving deep integration of microscopic observation and digital teaching. Built on the high-performance optical platform of the ER series upright biological / fluorescence / digital microscopes, the system meets multi-level experimental teaching requirements ranging from basic tissue observation to multi-channel fluorescence imaging, image acquisition and classroom collaboration. It serves as key supporting equipment for building smart laboratories and microscopic experimental teaching centers.
