Page 5: Introduction
1 Introduction 1.1 Atlas The Atlas 2D imaging system is the ultimate 2D imaging CCD combined Spectrophotometer choices with a spectrophotometer. The Atlas combines two fundamentally different Spectral engine (380nm-780nm) devices in one solution giving it unprecedented capabilities and flexibility. -
Page 6: Interfaces
Camera Ethernet connector 2.2 Power connection The Atlas is powered by a single power supply. Only use the power supply provided by Admesy. The use of other power supplies is not supported and may result to damage to the device. -

Core. Installation of the provided GUI is optional. It is also possible to develop a GUI based on the measurement needs. The Atlas Core is the heart of the Atlas, it takes care of everything. It controls the Atlas, it takes care of the calculation necessary for 2D analysis (Mura, uniformity…etc). -
