AOTF Hyperspectral Imagers
Brimrose AOTF Hyperspectral Imager is an optical-electrical integral system that can produce hyperspectral imaging of any target area by use of near-infrared camera and an Acousto-Optic Tunable Filter as a monochromator. We have introduced VA210 AOTF hyperspectral imagers and IS510-0.9-1.7 AOTF hyperspectral imagers.

The VA210 AOTF hyperspectral imaging adapters are designed for measuring visible or NIR hyperspectral imaging information on a variety of materials. The video adapter is suitable for biological, biomedical research, military as well as online process monitoring and waste material sorting. Specially designed visible, NIR, and MIR spectral imaging systems have been utilized for environmental monitoring and remote sensing. The imager will feature a 6.4×4.8 mm InGaAs Sensor with high spatial resolution up to 2560×1920 pixels. It also has a high spectral resolution and equipped with radio-frequency drive software. Our AOTF hyperspectral imaging System provides enhanced image quality and is optimized for minimum image distortion. View Enlarged picture

The miniature AOTF SWIR Hyperspectral Imaging Spectrometer IS510 series are designed for SWIR spectral imaging and can be used for telescope or microscope applications. The AOTF imaging system with Brimrose synthesizer Electronics provides a narrow bandwidth, rapid wavelength selection, and intensity control. This Imaging Spectrometer system comprises an integral system that can produce hyperspectral imaging on any target area, including microscopic (with an adequate adapter) by use of a 2-D InGaAs camera and Acousto-optic Tunable Filter as a monochromator. This unit includes image acquisition and AOTF control electronics in a single package unit that can be easily interfaced with any laptop PC (running WinXP+). The AOTF Controller, a high performance RF frequency synthesizer is incorporated into an OEM aluminum case. The framegrabber used is an express card. View Enlarged picture

Brimrose also designed the first Brimrose SWIR f22.5 mm lens for 0.8~1.7 mm wavelength range. It is the best performance with Brimrose VA210-0.9-1.7 video imaging adapter, IS210-0.9-1.7 or IS510-0.9-1.7 AOTF hyperspectral imager.
