Gamma Scientific Unveils LED Spectroradiometer

Aug. 5, 2003
San Diego, CA, August 5, 2003. - Gamma Scientific has unveiled the GS-1253-LED, a laboratory-grade LED spectroradiometer that offers high linearity, color accuracy and repeatability at a mid-range price. The GS-1253-LED can measure a broad range of LED spectral characteristics, including luminous intensity, color purity, spectral luminous intensity, low uncertainty chromaticity coordinate measurement, dominant wavelength and correlated color temperature of white illuminares.

San Diego, CA, August 5, 2003. - Gamma Scientific has unveiled the GS-1253-LED, a laboratory-grade LED spectroradiometer that offers high linearity, color accuracy and repeatability at a mid-range price. Ideal for production line testing, the GS-1253-LED can measure a broad range of LED spectral characteristics, including luminous intensity, color purity, spectral luminous intensity, low uncertainty chromaticity coordinate measurement, dominant wavelength and correlated color temperature of white illuminares.

"The GS-1253-LED is truly in a class of its own," said Richard Austin, president of Gamma Scientific. "No other LED measurement system on the market can match its performance. Yet it's competitively priced - just $15,500 - making it an exceptional value."

Several factors contribute to the GS-1253-LED's superior capability. These include leading-edge photodiode-array technology, very-low thermal-expansion materials and a proprietary LED mount that meets the recommended standard from CIE Pub. No. 127. All are incorporated into Gamma Scientifics' popular RadOMA platform, a durable optoelectrical design proven in hundreds of production lines worldwide.

"Conventional CCD-based measurement solutions simply cannot keep up," states Austin. "For example, we recently performed side-by-side comparisons with leading CCD-based systems. The GS-1253-LED consistently delivered 0.1 nm versus 3.0 nm repeatability in dominant wavelength. Moreover, its near real-time data acquisition-33 samples per second-was about 33% greater than the nearest competitor."

The GS-1253-LED is available in 360- to 780-nm spectral ranges (380- to 810-nm nominal also available), and includes auto dynamic range optimization, an IEEE-488 interface, USB interface and powerful Windows-based control/analysis software.

NIST-traceable and self-calibrated, the GS-1253-LED saves the user considerable time and money by eliminating downtime. Calibrations are easily performed via the Windows-based software and a range of highly stable and repeatable light sources available from Gamma Scientific. The system can also tie to a new low uncertainty detector-based candela standard.

Gamma Scientific is an optical radiation calibration laboratory and leading manufacturer of electro-optical instruments, including photometers, colorimeters, laser eye safety power meters and various other light measurement devices. For more information, visit www.gamma-sci.com .
