We have designed a spectrometer with the following unprecedented characteristics:

 

Some tradeoffs are available among the above parameters, for example speed and spectral resolution can be traded according to the red line below up to 100 kHz spectral acquisition rate:

Spectral acquisition rate

Selected applications:

Ultraspectral video processing

 

 

Possible paths for developing this technology:

Approximate minimum budget for one unit:

Parts

$200k

Design, construction, and testing

$80k

Total

$280k

[1] in most cases, fundamental and weaker overtone/combination bands are simultaneously monitored in this spectral range, allowing for a large dynamic range in sensitivity.

[2] Absorption and emission spectroscopy are both possible, depending upon the thermal characteristics of the imaged scene.
