Old Digital Rebel conversion to NIR

This is exactly the kind of thing I think we're looking for in part. Do you know if it was a filter or an actual sensor for NIR such as you would find on a satellite or advanced RS camera (ie something that actually registers NIR as a band rather than just filtering it out)? There are RS cameras that have 7-band sensors, but they are 10,000$+ at a minimum and our needs are just for a single NIR band. This is for my job rather than personal use as it sounds like it is for you.

Thanks

Life Pixel removes the internal filter, which is what limits the response of a camera's sensor to visible light only, and replaces it with a custom full spectrum filter which passes a wider range of wavelengths, UV, VIS and NIR. With the limiting internal filter gone, the sensor has the full range of response of silicon (roughly 400-1000 nm; some minimal response from 300-1100 nm). Then you could use external filters to select the range of interest to you. Note that in the spectral response curves at the maxmax link I gave above, while most of the NIR response is in the red channel, there is some response to NIR in the blue and green channels (because the dyes used in the Bayer filter array were not selected with filtering out NIR in mind; visible cameras are designed and manufactured only considering wavelengths from 400-700 nm, because that is what is passed by the factory-installed internal filters LifePixel is replacing).
