Brimrose Corporation of Americahas introduced a new series of Acousto-Optic Tunable Filter (AOTF) Camera Video Adapters. This Adapter is designed for NIR spectra imaging and has a Nikon 70-300mmSRL objective lens 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 1280 X 960 pixels.
