7B10.19 - Grating Spectrometer - Ocean Optics Spectrometer

Code Number:
7B10.19
Demo Title:
Grating Spectrometer - Ocean Optics Spectrometer
Condition:
Excellent
Principle:
Spectroscopy
Area of Study:
Modern

Disclaimer

Equipment:
Pasco Student Spectrometer with Grating, Light Sources.
Procedure:

Video Credit: Jonathan M. Sullivan-Wood.

Calibrate the optics rail type spectrometer.  This can take considerable time so make allowances.  Then place the desired light source in front of the slit.

The Ocean Optics spectrometer is a very neat and easy to use grating spectrometer.  Ours has a range of 300 to 1100 nm.  Just point the fiber optic cable at the desired light source and the spectrum appears.  Picture 3 is a spectrum of the fluorescent lights in Rm. 58 Van.
