Spectroscope. Spectrometer is the machine to give the readings.
Spectroscope can be made using
- Diffraction grating; eg. CD or DVD disk, or
- Natural gratings: Striated muscle, peacock feathers, mother-of-pearl, and butterfly wings. Some invertebrate animals, like the peacock spiders, the antennae of seed shrimp, and Burgess Shale fossils
- Iridescence in birds, fish and insects is often caused by thin-film interference
