High Speed VIS/SWIR AOTF Hyperspectral Imagers

Date Announced: 12 Mar 2025

Brimrose Corporation of America is proud to introduce a new series of miniature VIS and SWIR Hyperspectral Imagers (HSI). Brimrose’s HSI are based on an Acousto-Optic Tunable Filter (AOTF) that acts as an electronically tunable spectral band pass filter. It is a solid state device with no mechanical moving parts and is immune to vibration. It is designed to work in the laboratory or in harsh environments on installations such as large drones, aircraft, or other vehicles.  The utilization of the AOTF into the imaging system offers unmatched spectral flexibility in terms of scanning speed over the full range or random hopping on wavelengths of interest.

Using standard Brimrose software, the target or area of interest can be viewed at a user specified wavelength in real-time. Also, our standard software offers customizable exposure time, automatic gain, dynamic range optimization, user adjustable system signal response and non-uniformity correction, image zoom during acquisition and many more.  The proprietary design of Brimrose AOTF HSI offers high spectral resolution as low as 1nm in the VIS region and high spatial resolution.

Support control electronics allows end user's camera to capture up to 2,000 wavelengths/frames per second.  The AOTF HSI provides the complete spectrum of each pixel to the end-user for further analysis or image processing. Spectral data cubes are saved in “.png”, “.txt” or “.bsq” formats and are compatible with ENVI software.

Brimrose AOTF HSI is a cost effective, rugged, and compact design that offers superior speed, image performance, high signal to noise ratio, wide field of view and is suitable for various food, biomedical, pharmaceutical and military applications.  A c-mount interface makes it compatible with any microscope for biomedical research such as cancer detection, Raman or Fluorescence Spectroscopy.
