Hyperspectral Imager (IMAGE) Optica Caption Researchers used 3-D printing to make the holder (black rectangular piece) for the optics used to create an inexpensive and small hyperspectral imager. Feasibility tests showed that 3-D printing can be used to produce prototype parts that are accurate enough for optical systems.
