Customer Reviews
Use this apparatus as a sodium vapor light source. Includes 2 millimeter and 4 millimeter holes, with 4 millimeter x 20 millimeter vertical slit. The lamp power supply housing provides two intensities of operation. The lower intensity provides the more pure sodium vapor performance because the gas in the lamp runs cooler and is a more predominantly monochromatic sodium source. Using a spectroscope, the sodium 'doublet' is clearly visible and this lamp is suitable for general purpose monochromatic work in the classroom when used at the low power setting. The high power setting is useful to demonstrate the change in overall color as the various other wavelengths begin to appear. Operating voltage is 110 Volts (V).
