THE 2-MINUTE RULE FOR COOLED LONG-WAVE INFRARED LENSES

The prerequisite to maintain a similar graphic sharpness needs precisely the same increase in aperture. In this waveband all the conventional lenses could be thought of as properly diffraction confined and so the width of the PSF is: STINGRAY get off the bed each morning. Where D may be the diameter of the aperture of the optical process. Due to t
