FIELD: optics.
SUBSTANCE: optical unit comprises an optical element and an image plane curvature correction element. The optical element is made in the form of an integral base optical element, comprises an integrated two-mirror focal system and at least one integrated two-mirror afocal system. Multiple switchable optical elements (SOEs) configured to switch between a first state of transmission of optical emission of the visible spectrum and a second state of absorption or reflection of optical emission of the visible spectrum are placed on the front side of the optical element. The image plane curvature correction element is located behind the optical element.
EFFECT: provided multiple fields of view with the possibility of switching between the multiple fields of view.
