Spectral measurement, goniometric system for LEDs

Gamma Scientific, Inc. introduces the 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 Gamma's 940 LED measurement goniometer. 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 self-calibrating system features near-perfect repeatability via Gamma's RadOMA opto-electrical platform. The interchangeable device operates over a wide spectral range via four models that feature 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 nm to 550 nm, 260 nm to 900 nm, 300 nm to 1100 nm and from 380 nm to 810 nm.

The goniometric system features 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.
