For Angular and Spectral Measurement of LEDs
SAN DIEGO, March 6, 2008 -- Gamma Scientific said its new RadOMA-LED goniometric system combines RadOMA multielement arrays with the high sensitivity of backside-thinned CCD detectors available only with its 940-LED measurement goniometer to provide fast, highly accurate and repeatable LED angular and spectral measurements.

The advanced instrument’s low-light-measurement capabilities and blue-light region sensitivity offer improved performance and higher sensitivity than is available with conventional, front-illuminated CCD-based systems, Gamma Scientific said.

The control software provides a choice of two different formats for export to Microsoft Excel automatically at the end of each measurement for sharing information.

The self-calibrating system features near-perfect repeatability via its RadOMA optoelectrical platform, Gamma said. 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 to 550 nm, 260 to 900 nm, 300 to 1100 nm and from 380 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, the company said.

The RadOMA-LED system is available and shipping now.

Combining adjacent pixels into one larger pixel, resulting in increased sensitivity and lower resolution, or, in image analysis, excluding objects based on shape, position or area.
The qualities of color associated with hue and saturation, but not brightness or lightness.
1. A device designed to convert the energy of incident radiation into another form for the determination of the presence of the radiation. The device may function by electrical, photographic or visual means. 2. A device that provides an electric output that is a useful measure of the radiation that is incident on the device.
Characteristic of a surface or object that has luminous flux incident upon it.
The technology of generating and harnessing light and other forms of radiant energy whose quantum unit is the photon. The science includes light emission, transmission, deflection, amplification and detection by optical components and instruments, lasers and other light sources, fiber optics, electro-optical instrumentation, related hardware and electronics, and sophisticated systems. The range of applications of photonics extends from energy generation to detection to communications and...
