The embodiments relate to systems and methods for wavefront error (WFE) correction of a conformal optical component using a planar lens. The embodiments include a conformal optical component transmissive to electromagnetic radiation (EMR), which is propagated through the conformal optical component along a path axis. The conformal optical component is rotationally asymmetric about the path axis. A planar corrector lens is configured to correct a WFE of the conformal optical component. The planar corrector lens defines a lens axis. Accordingly, use of a single planar corrector lens for WFE correction of a conformal optical component reduces bulk and manufacturing complexity.

A system including a sensor to receive scattered light from a scene in a thermal infrared spectral region, a Modified Integrated Thermal (MIT) band filter to acquire MIT band data within a thermal detection bandwidth, a sub-band filter to acquire a first sub-band data within a first sub-band bandwidth which is within the thermal detection bandwidth. The sub-band filter is a Reference band filter to capture Reference band data or a Reststrahlen band filter to capture Reststrahlen band data. The system also includes one or more processors configured to perform differencing of the MIT band data and the first sub-band data to compute a second sub-band data. The computed second sub-band data is Reference band data when the sub-band filter is the Reststrahlen band filter or the computed second sub-band data is Reststrahlen band data when the sub-band filter is the Reference band filter. A method and a computer software product are also disclosed.
