Abstract
An optical system includes, from an image side to an object side, a first lens having a positive refractive power, a second lens having a positive refractive power, and a third lens having a negative refractive power. The first lens, the second lens, and the third lens form an optical path with the object side facing a screen and the image side adapted to provide an image from the screen to a user. In one aspect, the optical system is adapted to correct at least one of a group of aberrations including astigmatism and field curvature; or, lateral color.
Claims32
An optical system, comprising, from an image side to an object side:
- a first lens having a positive refractive power;
- a second lens having a positive refractive power;
- and
- a third lens having a negative refractive power;
- wherein the first lens, the second lens, and the third lens form an optical path with the object side facing a screen and the image side adapted to provide an image from the screen to a user.
An optical system for producing an image, comprising:
- a plurality of lenses forming an optical path having an object side facing a screen and an image side adapted to provide an image from the screen to a user, wherein the plurality of lenses corrects at least one of:
- a group of aberrations including astigmatism and field curvature;
- or
- lateral color.
A method of providing an optical system, comprising:
- locating a first lens having a positive refractive power at a position at an image side of an optical path;
- providing a second lens having a positive refractive power;
- and
- locating a third lens having a negative refractive power at an object side of the optical path, wherein the second lens is positioned between the first lens and the third lens;
- and
- wherein the first lens, the second lens, and the third lens form the optical path with the object side facing a screen and the image side adapted to provide an image from the screen to a user.
