Tuneable hyperspectral filter 300-1100nm

[Carole]

Any-one seen this?  Can't seem to find it anywhere else except on Facebook.

Prototype hyperspectral filter. 30nm bandpass (adjustable), compatible with any type of camera. Stepless bandpass selection via an electric actuator. Designed for agriculture and UAV (and other) sectors, but could show promise for astroimaging. This video shows a clip of a Euro note going from 1100nm down to 300nm. Could this be the only filter you ever need? Please excuse video quality, it was made with just a webcam.
