Welcome to our repository of free spectroscopy software drivers! We’ve created these driver libraries for developers who want to integrate our spectrometers into your own C/C++, Python or C# applications, or for advanced users who wish to control our spectrometers from interactive graphical environments like LabVIEW or MATLAB. We strive to make our systems intuitive and easy to use from all the world’s most popular software frameworks – with tools to simplify your data collection and analysis.
(As a reminder, technically you don’t need to use our application libraries at all — if you want to talk to the spectrometer’s hardware USB interface directly, you can do so using the ENG-0001 USB API document published on our Technical Resources page.)

Wasatch.NET Application Driver
Nearly every Windows programming language and framework provides some way to hook into Microsoft’s immensely popular .NET foundation. Our WasatchNET.DLL makes it simple to instantiate Spectrometer objects and access their methods and properties as easily as your own native classes. Explore our various demos and sample code to see how easy integration can be, or directly browse the open-source source code to quickly grok the data structures and signatures underlying each function.

C/C++ Application Driver (Windows, Linux, MacOS)
If you prefer a stripped-down C or C++ library with absolutely no “managed code” or .NET net entanglements, Wasatch.VCPP could be for you. The “VCPP” stands for “Visual C++” to guarantee full support for Microsoft Windows and Visual Studio, but Makefiles are included for you command-line Linux nuts. Like libusb itself, it’s universal!
