Wide angle projection lens and projection display device
A wide angle projection lens consists of a Gnp lens group having positive refractive power and a Gf lens group having positive refractive power in the order from a large conjugate side toward a small conjugate side, and further the Gnp lens group consists of a Gn lens group having negative refractiv...
