For the unique characteristics of Offner hyper-spectral imaging instrument with a convex grating

it has become one of the most important remote sensors. A compact integrated hyper-spectral imaging system

which is composed of two combined normal glass elements and the size of 30mm×30mm×30mm

is reported. The optimized hyper-spectral imager，which works at the visible wavelength band is faster than F/2.5

unit magnification

flat field

and both objective and imagery tele-centric system. It has the advantages of excellent imaging performance

high spectral resolution

compactness

lightness

good stability

good producibility

and low cost. And it may be widely used in the field of aerospace

biomedical science

etc.
