Key Features
8-pin base for compatible spectrum lamp holders and power units
Emits discrete spectral lines for emission spectrum work
Placed near the entrance slit of a spectroscope or spectrometer
Supports prism dispersion and diffraction grating experiments
Light from the excited atoms or vapours in the lamp forms separate bright lines rather than a continuous spectrum, which is the basis of emission spectroscopy. Used with a spectrometer, the lamp gives students lines to identify and measure in physics and chemistry classes.
Frequently Asked Questions
Does the Spectrum Lamp 8 PIN need a special holder?
Yes. It must be used with a compatible 8-pin lamp holder and power unit; check that the lamp gas type and electrical rating match the supply before use.
