The current version of the spectrometer is contained within a wooden box but here are the core components.
1. Concave holographic diffraction grating.
2. Printed acetate slit from Public Labs.
3. Sony ILX511B CCD
4. Custom made circuit controlled by an Arduino Nano to operate the CCD and transmit data to a computer for display.
There is ALOT more to be added about the project in its current state and future progress but for the time being I am investing most of the free time I have to another project, PULSE: Profiler Underwater Light SEnsor., for the Hackaday 2016 prize.
Hi Adam, thank you for charing your ideas and work! Since several years I own 2 Horiba mirrors (532 00 570, ~42.5mm square). So your case would be great for them. What size is your used grating? How do I have to scale your housing to match my mirrors. Do you know these models? I did not find any specification. Best regards from Bavaria, Martin
