24-W RF-powered Light sources are reliable, compact, and maintenance-free sources of gas spectral lines and continua from the 25 to 7,000 NM. These light sources are sealed with UV/IR windows, packaged in EMI-shielded enclosures, and have operating lives of thousands of hours. Standard and custom mounting flanges are offered to adapt the source to the user’s optical system or vacuum chamber.

Specifications for Hydrogen and Deuterium Light Sources HHeLCMM-L, DHeLCMM-L
The Hydrogen or Deuterium Light sources comes standard with everything needed to produce VUV radiation in the 110 to 200 nm region. A heater on the light source bulb generates H2 or D2 in the light source. This allows the user to operate the light source at low H2/D2 levels for an “optically thin” Lyman-Alpha line or a multiple-lined H2 or D2 spectrum in the 110 to 165 nm region and a continuum between 165 and 375 nm.•Continuously variable heater temperature setting that allows:o“Optically thin” source of Lyman-Alpha radiation (121.6 nm) or with heater adjustment a broadband VUV UV light source ouput from 112 to 400nmoHydrogen/Deuterium spectral output from 112 to 6000 nm•Air-cooled, optically stable (typically <1% drift per hour•Longer lifetime than most availble Lyman-Alpha sources owing to an internal source of hydrogen•Breakout box fo r RS-232 telemetry, BNC modulation input (if equipped), power switch, and USB interface for interface software ( see software manual)•“Smart Light Source” software allows for precise control and monitoring of light source parameters (heater, RF power etc.)oVisible NIR source emission intensity graphing and logging for tracking source stabilityoTemperature and RF power logging and graphing via graphical chart-recorder interfaceoExcel-friendly .csv output format for data saving•Configurations:oHHeLM-L, HHeLM-LOT are physically identical but have bulbs selected for high Lyman Alpha output which is verified by taking VUV spectra. They are delivered with the heater setting optimized for lyman alpha output. The HHeLM-LOT are additionally verified to have an “optically thin” Lyman alpha line by measurement of the absorption of the VUV emission by atomic hydrogen.oThe H2HeCM-L and H2HeCW-L light sources have the same physical configurations as the HHeLM series except for the lamp bulbs. Lamp bulbs in these lamps are configured for concentration of the plasma along the bulb axis. This allows operation at higher H2 pressures which increases optical power of the 110 to 165 nm H2 molecular and the 165 to 400 nm H2 continuum spectra. The H2HeCM-L bulbs are optimized for flood applications while the H2HeCW-L bulbs are optimized for coupling to wavelength filtering devices such as monchromators.

Rare Gas Light Sources
The Resonance Argon Krypton and Xenon Rare Gas Light source comes standard with everything needed to produce VUV radiation in the 110 to 200 nm region. They employ RF-excited bulbs with Magnesium Fluoride windows in EMI shielded enclosures. The line sources are filled to a few Torr and emit narrow emission lines in the VUV. The continuum sources are filled to 30 to 400 Torr Ar, Kr or Xe and emit both lines and continua in the VUV (see spectra below).•Air-cooled, optically stable (<1% drift per hour)•Longer lifetime than most available Rare gas sources owing to an internal source getters and “hard seal windows”•Breakout box for RS-232 telemetry, BNC modulation input (if equipped), power switch, and USB interface for interface software (see software manual)•“Smart Light Source” software allows for precise control and monitoring of light source parameters (heater, RF power etc.)oVisible NIR source emission logging and graphing for tracking source stabilityoTemperature and RF power logging and graphing view graphical chart-recorder interfaceoExcel-friendly .csv output format for data saving
