Pin cushion distortion correction lens |
| abstract |
A pin cushion distortion correction system for magnetically deflected cathode ray tubes in which a planoconvex lens adapted to optically correct for pin cushion distortion is disposed in front of the cathode ray tube. The curvature of the lens is suitably selected to impart greater optical gain in the center and lesser optical gain towards the edges so as to complement, and thereby cancel or correct, the pin cushion distortion. |
