Abstract

Remote sensing applications require monitoring ground reflectances through the visible and into the infrared spectrum. Many refractive designs exist for the visible (0.4μm to 0.7μm) as well as medium-wave infrared, MWIR, (3.0μm to 5.0μm) applications. However, design solutions that bridge the gap between these two spectral regions are not very common. Recent work at SBRC has uncovered several solutions with reduced secondary color in the 1.0μm to 3.0μm band and that even extend from 0.5μm to 5.0μm.
