Use the Spectroscope for quantitative examination of the spectral composition of white light and radiant bodies. It is comprised of a metal draw-out tube of 0.75″ (20 mm) Dia. with an adjustable slit at one end. The light passing through this slit falls on the prism elements and breaks up into a spectrum. This can be viewed through an eyepiece at the other end of the tube.
• Comes with a Teacher’s Guide
• Supplied in a velvet-lined wooden box
• Fully drawn out 5″ (130 mm) L

Use these tubes to show spectral lines of pure substances. These are glass tubes approximately 10.25″ (260 mm) long, central capillary portion approximately 3.5″ (90 mm) to 4″ (100 mm) long, with electrodes sealed at both ends and connected to lead wires protected by metal caps. The tubes offer an exciting illustration of spectral lines.
• The tube requires an induction coil 2″ (50 mm) spark, or a suitable transformer like our Power Supply (Item #3376-00D, not included)
• Length of capillary portion can be varied as required
• These cannot be used as lamps
• For intermittent use
• Spectrum – Pink
