ProStar* 120° lens
For the projection onto a curved (spherical) screen ISCO has designed the ProStar* 120° lens for 1,3” LCD projectors. The 120° lens is optimised for a projection from the centre of a hemisphere. Projecting from that spot does not cause any distortion on the screen. With three projectors in the centre an image of 360° x 90° can be covered. Areas of use are planetariums, simulations and many different special applications.
