Educational Spectrophotometer System with Sensors

Product Code: OS-8450


PASCO’s Educational Spectrophotometer teaches basic optical principles and allows quantitative measurements rivaling those of more expensive units.

When the Spectrophotometer is used with PASCO’s Capstone software, students can explore the relationship between angle, wavelength and intensity and graph the spectral lines from discharge tubes. Lines from mercury, sodium, helium, neon, krypton and argon can be plotted— even the lines of the Balmer series in hydrogen can be detected.

Students can also analyze the transmission characteristics of filters, chemical solutions and even the absorption spectrum of a leaf. Few instruments can be used to teach so many aspects of science.

Note: The open design of this spectrophotometer system is ideal for education. It is not intended for industrial or research applications.
