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.
"A
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."
These
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.
"The
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.
