The Olympus DP23-AOU and DP28-AOU are control unit sets designed for Olympus microscope digital cameras, specifically the DP23-CU and DP28-CU models. These units allow the microscope digital cameras to operate in a standalone mode when combined with the DP2-AOU control box.
Function Description:
The primary function of these control units is to facilitate the capture and storage of digital images from a microscope. They provide a comprehensive interface for controlling camera settings, acquiring still images and movies, playing back recorded media, performing measurements, and managing system settings. The system is designed for use in a commercial environment, not for clinical diagnostic purposes.
