Original Press Release:

Konica Minolta Sensing Americas and B&W Tek Inc Announce SpectraRad(TM) Irradiance Meter

Konica Minolta Sensing Americas, Inc. (KMSA), the worldwide leader in the industrial measurement of color, light and shape has partnered with B&W Tek, Inc. an advanced instrumentation company producing optical spectroscopy and laser systems to introduce a new, lower cost option for LED characterization.

Together, they announce the new thermoelectric (TE) cooled miniature spectral irradiance meter, the SpectraRad(TM), filling the need for a midrange irradiance meter in the Konica Minolta product line.

The SpectraRad(TM) is a miniature TE Cooled Spectral Irradiance Meter designed for industrial and laboratory light measurement applications with a USB 2.0 interface. It is equipped with a right angle, fiber-optically coupled cosine corrector and is irradiance calibrated against a NIST traceable tungsten light source. BWSpec(TM) software, included, provides for the characterization and measurement of many lighting devices and systems. The standard software features include time line recording, data smoothing, illuminance (lux), chromaticity, color temperature, externally triggered pulsed light capturing, and other data-handling functions. The SpectraRad(TM) is ideal for lamp and LED characterization, color analysis, photostability testing, photobiology and photochemistry.

"The advantage to users is that SpectraRad(TM) is a low cost, high resolution, high sensitivity, Thermoelectric Cooled CCD array spectral irradiance meter. This solution offers a high dynamic range with superior long term stability. It is ideal for various applications including low light level detection and long-term monitoring applications", said Randy Klimek, New Product Project Manager for KMSA.

The SpectraRad(TM) offers significant improvements over traditional filter based technology instruments. Filter based instruments have been desired for certain properties (cost, speed and portability) but lack the resolution to accurately describe the spectral characteristics of a light source. Filter based instruments only acquire average three data points across the entire spectrum of light to yield colorimetric values. This is accomplished by the use of filters corresponding to the normal human eye response. These filters can only be manufactured to a certain degree of accuracy. Due to these facts, filter based meters are susceptible to errors because of the deviation of the filter response from the ideal human eye response and the lack of resolution needed to accurately describe narrow bandwidth light sources.

The SpectraRad(TM) avoids these problems at a comparable cost, higher speed and small footprint because it acquires hundreds of data points across the visible spectrum. The 2048 pixel linear CCD array provides the precision required to accurately measure narrow bandwidth light sources or LEDs. Having multiple sensors also enables the unit to report spectral data and display spectral graphs, making it the ideal instrument for evaluating LEDs, which is today's dominant light source.

The SpectraRad(TM) will be sold and distributed exclusively by KMSA in North America beginning Oct 1, 2010 and will be available for purchase online at
