FIELD: physics.
SUBSTANCE: device for virtual image displaying contains a video element, a lightguide element, a projection lens. In this case, the light guide element contains five surfaces that reflect light. Moreover, two surfaces of the light guide are made with asymmetrical curved surfaces, and the projection lens includes the lens surface in the form of a non-axisymmetric aspherical surface.
EFFECT: providing a wide viewing angle, reducing the size and weight.
