Q16: Hg Light Source
Purpose: To demonstrate the properties of a specific gas in a light source.
Description:

With a good spectral light source, students can investigate energy levels using a spectrometer or qualitatively examine the atomic fingerprints through an optical slit. PASCO's light sources are the toughest, most reliable light sources available for the student lab, providing clean, high-intensity spectral light. With a rated output of 100 watts and 3000 lumens of light in the mercury spectrum, this source provides sufficient intensity for almost any experiment. The outer glass envelope attenuates the undesirable ultraviolet radiation. The lamps provide 24,000+ hours of trouble-free operation. The light ports are 3.2 cm in diameter and are 22.5 cm high. This light source is supplied fully operational with built-in power supply, housing and lamp. Operating voltage is 115/220 VAC, 50/60 Hz.
