This 3D-printable DIY CCD spectrometer is a compact and efficient tool for optical analysis, science experiments, and DIY spectroscopy. Designed for ease of assembly, this spectrometer uses a fixed slit and a 1000 lines/mm transmission grating to disperse light onto a CCD sensor or webcam, allowing for spectrum analysis.

Whether you're a science enthusiast, educator, or hobbyist, this model provides an accessible way to explore light wavelengths, material properties, and spectral emissions.

Features & Benefits:Precise Optical Design – Uses a fixed slit for stable and accurate spectrum readingsCCD or Webcam Compatible – Works with common CCD sensor modules or modified webcams1000 Lines/mm Transmission Grating – Ensures sharp spectral separationFully 3D-Printable – Designed for easy assembly with minimal additional componentsCompact & Sturdy – Ideal for DIY laboratory setups, education, and research.Light Spectrum Analysis – Study emission & absorption spectraDIY Science Projects – Explore spectroscopy at homeMaterial & Chemical Identification – Useful for lab experimentsEducational Demonstrations – Teach students about light & wavelengthsAstronomy & Environmental Science – Measure spectra from various light sources

Required Components (Not Included in STL):

To complete this spectrometer, you will need:

1x 1000 lines/mm transmission diffraction grating, holographic film works well 1x CCD sensor module OR modified webcam M2 screws, nuts and four 10mm long spacer nuts for assembly The free software Theremino Spectrometer works well with this setup

These components can be sourced from online electronics suppliers or optical component retailers.You only have to fit the grating into the adapter, lines from up to down and focus the CCD to the grating, You may need some assembly work and fine-tuning to achieve optimal performance. The narrower the slit, the higher the accuracy. It is recommended to print the components in black material and then paint them matte black for optimal performance.
