BrimroseCorporationofAmericahasintroducedanewseriesofAcousto-OpticTunableFilter(AOTF)Camera/TelescopeVideoAdapters
Brimrose Corporation of Americahas introduced a new series of Acousto-Optic Tunable Filter (AOTF) Camera/Telescope Video Adapters. This Adapter is designed for visible and NIR spectra imaging. VA-210 has Nikon >50 mmSRL objective lenses in front of the AOTF. The AOTF imaging system with Brimrose Synthesizer Electronics provides narrow bandwidth, rapid wavelength selection, and intensity control. The designed wavelength ranges depend on the camera lens and Brimrose's AOTF devices. The high spatial resolution of the AOTF Camera system will be up to 1280x960 pixels at 586nm.
