Introduction

A spectrometer is a device used to measure properties of light over a specific portion of the electromagnetic spectrum. Build your own spectrometer at home using simple materials and explore the fascinating world of light analysis.

Materials and Tools

• DVD or CD (used as a diffraction grating)
• Cardboard box
• Black electrical tape
• Razor blade or craft knife
• Scissors
• Ruler
• Protractor
• Smartphone with camera
• Glue or adhesive

Step-by-Step Construction

Follow these steps to construct your DIY spectrometer:

1. Prepare the Diffraction Grating: Cut a piece of the DVD or CD to use as a diffraction grating. Carefully peel apart the layers of the DVD using a craft knife to expose the reflective surface.
2. Construct the Spectrometer Box: Use the cardboard box to house your spectrometer. Cut a slit approximately 1 mm wide in one end of the box, which will act as the entrance slit for light.
3. Position the Diffraction Grating: Fix the piece of DVD at a 45-degree angle inside the box using glue or adhesive. The grating should face the entrance slit.
4. Create a Viewing Port: Cut a small square hole on the opposite side of the entrance slit. This is where you will position your smartphone camera.
5. Seal the Box: Use black electrical tape to seal any open edges of the box to ensure no light leaks in except through the entrance slit.
6. Calibrate Your Spectrometer: Use known light sources to calibrate your spectrometer, checking the spectrum captured by your smartphone camera.

Theory of Operation

A spectrometer functions by dispersing light into its component colors (spectrum), allowing for analysis of its intensity as a function of wavelength. The diffraction grating causes different wavelengths of light to diffract at different angles, creating a spectrum on the opposite side of the grating.

Applications

DIY spectrometers can be used to study light sources, analyze chemical compositions, or even investigate astronomical objects. They provide a hands-on approach to understanding spectral analysis in fields such as chemistry, physics, and environmental science.
