This was an early version of the Python GUI to control the Raman spectrograph.
The spectrum shown is not yet adjusted or calibrated
Adjusting the insertion/rejection filter is tricky.
The back of the spectrograph shows all the wiring.
The stack of motor shields on the Arduino Mega.
The front of the spectrograph with the black foam-core box which is for shielding the microscope from ambient light (needed for long exposures) and protecting the user from laser light.
The ChipKIT uC32 microcontroller controls the thermoelectrically cooled Hamamatsu detector.
The old control panel is no longer needed. It has been replaced by the Python GUI.
The microscope where the specimen is placed. Laser light is sent into the microscope from behind.
The early wiring of the motor controllers was messy, it has been cleaned up since then.
