How to Make DIY Spectrometer | Optical spectrum analyzer | Light analysis

This spectrum analyzer can analyze light, including infrared (IR) and ultraviolet (UV) light. It uses DVD Disk that works like a diffraction grating and splits light into the rainbow, the software then analyzes the rainbow. (A rainbow actually is the light spectrum) In this video, I also explain why incandescent light bulbs are not energy efficient. ABOUT SOFTWARE: I want to thank people from theremino for making the great software, here is their website: http://www.theremino.com And here is how to build spectrum analyzer, instruction from theremino: http://www.theremino.com/wp-content/uploads/files/Theremino_Spectrometer_Construction_ENG.pdf And here is the link to the actual software for the analyzer: http://www.theremino.com/wp-content/uploads/files/Theremino_Spectrometer_V2.5.zip M ...
