Each atom owns its unique energy level structure, absorbing or emitting specific spectral lines during transitions. By measuring these characteristic spectral lines, we can determine a substance's chemical composition and relative content—this identification method is called spectral analysis.

Examine interference and diffraction patterns for laser light passing through various single-slits and multiple-slits.

Measures intensity, absorbance, and transmittance across the visible spectrum. Includes fluorescent excitation at 405nm and 500nm.

Facilitates emissions spectroscopy experiments with the PASCO Wireless Spectrometer. Simply insert the Fiber Optic Cable into the cuvette holder and point the end of the cable at the light source.

Easy to use and inexpensive with a variety of safety features that make it suitable for beginning labs.

This Hydrogen Spectral Tube is 26-cm-long and capillary-thin over the middle 10-cm to provide sharp, bright spectra.
