Waves includes from your own software. It consists power supply (if USB is not used). sophisticated algorithms for data of a Windows DLL library for the The eight digital channels can be acquisition and evaluation, which .NET framework, documentation, configured as trigger input, shutter provides the following features and sample code. The SDK can or flash lamp control, process through a clear and straightforward be used with any programming control, or general purpose I/O user interface. language that can use .NET DLLs, pins. including C , Visual Basic .NET, Take and display series of spectra The Qmini supports three trigger C++, Delphi, LabVIEW, Matlab, and Automatic exposure control with modes: software trigger, interval Mathematica. dark spectrum interpolation trigger, and external trigger. It can be set to trigger on the start or the Import most ASCII-based file Communication Protocol end of the exposure period. formats The spectrometer can also Export as ASCII table to almost be directly controlled from an any numerical analysis software embedded microcontroller or other operating systems using the Comprehensive tools for device communication protocol. displaying and analyzing spectra Just like our application software, Strip charts for comparing the protocol is designed to be characteristic values between both powerful and easy to use for multiple spectra including peak software developers. follower in real time Qmini Schematic Drawing Graph printing and export to PDF Dynamic peak finder (no need to set a threshold level) 6.5 Dark spectrum interpolation 17.85 39.5 Transmission, absorption, and 34.35 35.5 reflection measurements 42 2.5 Colorimetry Waves is very easy to use and very intuitive. Various spectrum evaluation options are available with minimal effort and only a few mouse clicks. For example, to zoom in, adjust the zoom slider. To move around, adjust the scrollbar. To change the x-axis unit, select the corresponding button. Values such as peaks or colorimetry are instantly calculated as soon as 3.5 a spectrum is taken.
