Patent ID: 6882481

Claim:
An optical arrangement comprising: a first lens element having at least one first lens, said first lens element having a positive power, and wherein the radius of curvature of the surface of said first lens element proximate to an object plane is less than or approximately equal to the radius of curvature of the surface of said first lens element distal to said object plane; a second lens element having at least one second lens, said second lens element having a negative power; a third lens element having at least one lens, said third lens element having positive power; a fourth lens element having at least one lens, said fourth lens element having a negative power; a fifth lens element having at least one lens, said fifth lens element having a positive power; a sixth lens element having at least one lens, said sixth lens element having a positive power; a seventh lens element having at least one lens, said seventh lens element having a positive power, and wherein the radius of curvature of the surface of said seventh lens element proximate to said object plane is less than or approximately equal to the radius of curvature of the surface of said seventh lens element distal to said object plane; and, an eighth lens element having at least one lens, said eighth lens element having a positive power, wherein the distance from said first lens element to said second lens element is sufficient to reduce a ray height of a light ray entering said second lens element from the ray height of said light ray entering said first lens element and wherein the distance from said fifth lens element to said sixth lens element is sufficient to increase said ray height of said light ray entering said sixth lens element from the ray height of said light ray entering said first lens element.
