EnglishDefinition
A mercury-vapor lamp commonly used for general lighting purpose; it emits primarily in the blue and green.
Examples
- 1.High-pressure mercury vapor (and some specially-designed metal-halide) lamps find application in molecular spectroscopy due to providing useful broadband continuum ('noise') energy at millimeter and terahertz wavelengths, owing to the high electron temperature of the arc plasma; the main UV emission line of ionized mercury (254 nm) correlates to a blackbody of T= 11,500 K.
