ABSTRACT:
The invention provides an optical device for use in microscopes and screen projectors comprising a screen formed with multiple lenticular surfaces mechanically traversed at a speed above persistence of vision in the light path between an object and an observation plane, the lenticular surfaces increasing the angle of light ray pencil egress from their angle of incidence to an extent rendering the use of eyepieces unnecessary.
