The silver waveband stands for the Otterbach. Due to the introduction of the FM waveband the radio antennas were rebuilt. Reportedly, Sierra Nevada Corp. took over the contract from Waveband. Filters are sometimes added to the UV illumination source to narrow the illuminant waveband. Waveband Communications, Inc is an American Corporation. The OLS-30 is a combined IRST/LR device using a cooled, broad waveband sensor. In 2005, Sierra Nevada Corporation acquired WaveBand Corporation.
