Philip Harris Spectrometer - Intermediate

This intermediate spectrometer is designed for secondary schools and colleges, enabling students to explore the properties of light and analyse spectra in practical physics lessons. Ideal for teaching the fundamentals of atomic structure and light composition, it supports hands-on learning in spectroscopy.

The principle is simple; incident light is bent, or refracted, through an optical device such as a prism or diffraction grating. A spectrum is produced, each wavelength of light refracted by a unique angle. By measuring the angles at which light is refracted, a precise spectrum can be determined. By looking at what spectral lines are missing, otherwise known as an absorption spectrum, the composition of a body that does not emit its own light, such as a gas cloud, can be determined.

A spectrometer has applications in many areas of science, including astronomy and analytical chemistry. When combined with a Spectrum Lamp, Spectrometers provide an accessible way to teach this essential area of Physics.
