WESTFORD, Mass., June 8 2006 --Barr Associates Inc., a manufacturer of precision thin-film coatings
and optical filters, has introduced an 18-element multispectral filter
microarray. The company said each element is a high-precision thin-film
filter only 0.032 mms wide.
key driver of the development of filter arrays was the desire to reduce
mass, power and volume in multispectral sensors through the elimination
of a filter wheel," the company said in a statement. "The main
advantage of the new microarray technology is the increased number of
spectral bands, which can be accommodated in a smaller volume, and
their compatibility with higher-resolution detector arrays."
new microarrays may be designed and built for use with any focal plane
array detector, from ultraviolet to long-wave infrared wavelength
ranges, the company said. Potential applications include commercial
colorimetry and space-based multispectral imaging.
newly developed microarrays will provide a very rugged,
high-performance alternative to linear variable filters or diffraction
gratings," said Kevin Downing, product line manager of the Arrays
Product Line at Barr.
