Instruments

Viewer1D

• avantes: control of an Avantes AvaSpec ULS2048CL EVO spectrometer

Installation instructions

• PyMoDAQ 5.0.1
• tested: Debian Linux 11/12, Windows 11

• Drivers / binaries needed from Avantes

  • Linux: libavs.so (in libavs_..._amd64.deb)
  • Windows: avaspecx64.dll (AvaspecX64DLL_...Setup_64bit.exe)
  • MacOS: libavs.dylib
  • any: avaspec.py

Linux

• Avantes publishes a Debian installation package libavs_..._amd64.deb. Run

  sudo pdkg -i libavs_..._amd64.deb
  

  to install its contents. Depending on the configuration of the Linux brand you're using, the file may end up in a directory where the dynamic linker doesn't find it. If that happens to you, you may also install the dynamic library by hand by copying it to a location where the dynamic linker will find it on your system. On Debian you may chose /usr/local/lib/avantes as "home" for the library. Copy the file libavs.so.whatever.version.number to that directory and run inside that directory

  sudo ln -s libavs.so.whatever.version.number libavs.so
  

• Create (using sudo and your favorite editor) the file

  /etc/udev/rules.d/90-avantes.rules
  

  and set its content to

  SUBSYSTEM=="usb", ATTRS{idVendor}=="1992", ATTRS{idProduct}=="0669", MODE="0666"
  

• Connect the spectrometer and run

  sudo udevadm control --reload-rules
  sudo udevadm trigger
  

Windows

• Execute AvaspecX64DLL_...Setup_64bit.exe. The installer will ask you for a password which you have to get from the AvaSpec Library Manual which you should have received from Avantes together with the device.
• The setup program will install and configure the device driver. Connect the device and check the device manager for an entry named "Avantes Spectrometers".

Continuation on any OS

• Inside a shell (i.e. Miniforge Prompt on Windows) run

  pip install pymodaq_plugins_avantes
  

• Start the dashboard and create a preset using the avantes plugin.
