Neon Spectral Lamp, USB Powered - Thorlabs
WebA mercury-vapor lamp is a gas-discharge lamp that uses an electric arc through vaporized mercury to produce light. The arc discharge is generally confined to a small fused quartz arc tube mounted within a larger soda lime or borosilicate glass bulb. The outer bulb may be clear or coated with a phosphor; in either case, the outer bulb provides thermal insulation, … WebOct 12, 2024 · Thorlabs' CSL1 Neon Spectral Lamp is a USB-powered neon light source that produces stable, well-defined spectral lines within the 500 nm to 1100 nm wavelength … WebSep 23, 2004 · Sodium emits orange-yellow light, and a spectrograph reveals the color comes from two closely spaced spectral lines (see middle part of 2nd strip in the image above). Mercury vapor emits a bluish light (see middle of bottom strip above), but no red.
