Barr Associates, Inc.

Ball Aerospace and Technologies Corp of Boulder, Colorado recently selected Barr to develop, manufacture and test multi-spectral filters for the Operational Land Imager (OLI) they are building for NASA / USGS. These filters are very high performance versions of a filter array technology developed and refined over several years by Barr. Each filter assembly consists of nine individual spectral bands, thus the “multi-spectral” designation. A full instrument compliment consists of 14, closely matched filter assemblies.
