Image Characteristics Convex Lens Lenses Object: do > 2f pa 2F F Image Characteristics Real Inverted f < di < 2f hi < ho Any incident ray parallel to the principal axis will refract through the focus (on the other side of the lens). Any incident ray passing through the (near side) focus will refract parallel to the principal axis Any incident ray passing through the center of the lens will pass straight through the lens.

Image Characteristics Convex Lens Lenses Object: do = 2f pa 2F F Image Characteristics Real Inverted di = 2f hi = ho Any incident ray parallel to the principal axis will refract through the focus (on the other side of the lens). Any incident ray passing through the (near side) focus will refract parallel to the principal axis Any incident ray passing through the center of the lens will pass straight through the lens.

Image Characteristics Convex Lens Lenses Object: f < do < 2f pa 2F F Image Characteristics Real Inverted di > 2f hi > ho Any incident ray parallel to the principal axis will refract through the focus (on the other side of the lens). Any incident ray passing through the (near side) focus will refract parallel to the principal axis Any incident ray passing through the center of the lens will pass straight through the lens.

Image Characteristics Convex Lens Lenses Object: do = f pa 2F F Image Characteristics no image Any incident ray parallel to the principal axis will refract through the focus (on the other side of the lens). Any incident ray passing through the (near side) focus will refract parallel to the principal axis Any incident ray passing through the center of the lens will pass straight through the lens.

Image Characteristics Convex Lens Lenses Object: do < f pa 2F F Image Characteristics Virtual Upright di < 0 hi > ho Any incident ray parallel to the principal axis will refract through the focus (on the other side of the lens). Any incident ray passing through the (near side) focus will refract parallel to the principal axis Any incident ray passing through the center of the lens will pass straight through the lens.

Image Characteristics Concave Lens Lenses Object: Anywhere pa 2F F Image Characteristics Virtual Upright di < 0 hi < ho Any incident ray parallel to the principal axis will refract through the focus (on the near side of the lens). Any incident ray passing through (towards) the (far side) focus will refract parallel to the principal axis Any incident ray passing through the center of the lens will pass straight through the lens.
