Gamma Intros Spectral Measurement System for LEDs
San Diego, CA — Gamma Scientific, Inc. ( has introduced its RadOMA-LED Goniometric System for fast, highly accurate and repeatable, LED angular and LED spectral measurements. The new system combines the RadOMA multi-element array technology with the high sensitivity of backside-thinned CCD detector technology, available only with the company's 940 LED measurement goniometer.

According to the company, the advanced instrument's exceptional low light measurement capabilities and superior blue-light region sensitivity offers improved performance and higher sensitivity than is available with conventional, front-illuminated CCD-based systems. Designed for easy integration into existing systems with the high-speed USB interface, the modular instrument offers fast, accurate luminous and radiant intensity, dominant wavelength, peak wavelength, color temperature, chromaticity, tristimulus, Lab/Luv, CRI, full-width-half-max, and beam angle, with a user-selectable half-power bandwidth for accurate binning in a compact and affordable system.

The control software reportedly makes sharing measurement results easy by providing a choice of two different formats for export to Microsoft Excel automatically at the end of each measurement. The self-calibrating system has near-perfect repeatability using the company's RadOMA opto-electrical platform. The interchangeable device operates over a wide spectral range with four models that provide millisecond measurement speed and near real-time measurements.

Spectral wavelength ranges extend from the ultraviolet to near-infrared and include extremely high sensitivity over the blue-light region of the spectrum. The four optional modules offer detector wavelengths from 200 to 550nm, 260 to 900nm, 300 to 1100nm and from 380 to 810nm.

The goniometric system has two automated axes, including an automated axial range that eliminates the extra step of manual LED rotation associated with manual axial-range units. Comprehensive, built-in sockets accommodate a wide variety of LED standards.
