Patent ID: 8339600

Claim:
A dual waveband imaging spectrometer, comprising: an entrance slit for transmitting light, a first dioptric lens, a mirror, a dispersing prism with a reflective coating, an immersion grating with a reflective coating, a second dioptric lens, and a dual waveband detector; said entrance slit, said first dioptric lens, said mirror, said dispersion prism, said immersion grating, said second dioptric lens, and said detector array positioned wherein said entrance slit transmits light to said first dioptric lens, which refracts light to said mirror, which reflects light back through said first dioptric lens to said dispersing prism and said immersion grating, and dispersed dual waveband light is focused through said first dioptric lens and said second dioptric lens to said dual waveband detector.
