Energetiq Technology, Inc., a developer and manufacturer of ultrahigh-brightness, broadband light sources for advanced technology applications, today introduced a new light source to its established line of LDLS™ Laser-Driven Light Sources for use in radiometric calibration. The EQ-99CAL is a calibration light source that covers the complete UV to Visible spectral range with high brightness and stable output levels across that spectrum.
Traditionally, radiometric calibrations have been made using more than one light source, e.g., Deuterium/Tungsten-Halogen, since prior to the introduction of the Energetiq EQ-99CAL no one source could cover from 200nm – 800nm. Additionally, traditional sources need to be recalibrated often and lamp bulbs replaced after only 500 hours of use. The EQ-99CAL has a long interval between calibrations (1,000 hours or one year) and a long bulb life of more than 5,000 hours, resulting in a lower cost of ownership.
The EQ-99CAL has a very strong irradiance in the critical 350nm range, where in typical systems two separately calibrated Deuterium (D2) and Quartz Tungsten Halogen sources would experience overlap and add uncertainty to the measurement. At 350nm, an EQ-99CAL exhibits irradiance an order of magnitude higher than these traditionally calibrated D2 and Quartz Tungsten Halogen lamps.
The calibration of the EQ-99CAL is traceable to the National Physics Laboratory (NPL) in the UK, and a certificate of calibration is included with each unit.
