A Simple Gratting Spectrometer for Highschool

• This thing is a gratting holder for spectrum observation.
• It's made with wood and PLA parts.
• You can observe and measure wave length of spectral lamps after a calibration.
• It uses a transmission gratting slide with 530 grooves per millimeter.
• It can be disassembled to be stored on a shelf
