Page 4: Introduction
1 Introduction 1.1 Atlas The Atlas 2D analysis system is the ultimate 2D imaging CCD combined Spectrometer choices with a spectrometer. The Atlas combines two fundamentally different Spectral engine (380nm-780nm) devices in one solution giving it unprecedented capabilities and flexibility. -
Page 5: Interfaces
GUI software supplied on USB connector the USB stick Camera ethernet connector 2.2 Power connections Atlas has a single power supply. Always make sure to use the one supplied by Admesy. Others are not guaranteed to work and may even damage the Atlas. -
Page 6: Atlas Communication
You can install our standard GUI or you can make you own GUI. The engine software 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). -
Page 7: Gui
4.4 Atlas controlled remotely The graphical user interface sends commands trough TCP/IP from a different PC to the Atlas engine which on its turn takes care of the received command and sends back data to the GUI if applicable. Each software packages is on a different PC. -
Page 8: Device Drivers
5 Device drivers 5.1 Atlas engine In order to run the Atlas both the GigE driver and the NI-VISA are necessary. Atlas is only supported under 64 bit systems. NI-VISA GigE Windows 7 (64 bit) · · Windows 8 (64 bit) Not tested¹... -
Page 9: Command Set Structure
6.2 Command structure Every command starts with a colon “ : ”, which identifies the root of the The functions of the Atlas can be best described via the following categories. command tree. Each further keyword is also separated a colon. In case parameters need to be specified, the last keyword and parameters are ... -
Page 10: Data Communication
6.3 Data communication Write and read for 2D data commands Every command starts with a colon “ : ”, which identifies the root of the command tree. Each further keyword is also separated by a colon. In case parameters need to be specified, the first parameters is separated by a Send ASCII command terminated with CRLF. -

7.5.4 :CAPTure:XYZImage BLUE After finding the display and calibrating the Atlas 2D imager the real CAPIMG measuring can start. When this command is given the imager takes a image, transforms it to XYZ automatically and stores it in the engine. The XYZ image is stored under the name CAPIMG, which stands for CAPtured IMaGE. -
