Thick lens diagram
Images of black letters in a thin convex lens of focal length f are shown in red. Selected rays are shown for letters E, I and K in blue, green and orange, respectively. Note that E (at 2f) has an equal-size, real and inverted image; I (at f) has its image at infinity; and K (at f/2) has a double-size, virtual and upright image.

焦距,也称为焦长,是光学系统中衡量光的聚集或发散的度量方式,指从透镜中心到光聚集之焦点的距离。亦是照相机中,从镜片光学中心到底片、CCD或CMOS等成像平面的距离。具有短焦距的光学系统比长焦距的光学系统有更佳聚集光的能力。

The focal length of an optical system is a measure of how strongly the system converges or diverges light. For an optical system in air, it is the distance over which initially collimated rays are brought to a focus. A system with a shorter focal length has greater optical power than one with a long focal length; that is, it bends the rays more sharply, bringing them to a focus in a shorter distance.
