Begin spectroscopy with a simple, single-wavelength observation...
Then they’ll be prepared to view
traditional spectrum tubes.
An affordable and more durable solution than gas
discharge tubes, this LED light source produces known wavelengths of light
which can be used to verify the operation of handheld spectroscopes as well
as investigate the effects of color mixing and the principles of
spectroscopy. Four LEDs can be switched on or off independently and can be
used in any combination. The colors span the visible spectrum with Red (660
nm), Orange (610 nm), Green (502 nm), and Blue (470 nm). 2 AAA batteries not
included.
