WHAT DOES COOLED LONG-WAVE INFRARED LENSES MEAN?

The effects suggest which the correction capacity in the freeform lens is much more strong than that on the aspheric surface area specifically for large-get aberrations even whether it is used in rotating axisymmetric methods.Figure four displays the normalized MTF vs area angle for the 3 lens patterns useful for the 3 various detectors.
