Abstract
A visual optical system comprises a first optical system and a second optical system. The first optical system comprises a first lens having a positive refractive power, a reflective polarizing element, a quarter-wave plate, a second lens having a refractive power and a third lens having a positive refractive power. The second optical system comprises, sequentially along a second optical axis from the first side to the second side, first to sixth lens elements. An effective focal length f3' of the third lens, a distance TD′ from a first-side surface of the first lens to a second-side surface of the third lens on the first optical axis, an effective focal length f1 of the first lens element and a distance TD from a first-side surface of the first lens element to a second-side surface of the sixth lens element on the second optical axis satisfy: 1.9<(f3′/TD′)/(|f1|/TD)<5.7.
