ABSTRACT:
A collimating optical system for collimating a diverging light beam through a spherical lens meets the following relation: ##EQU1## where n is refractive index of the lens, f is a focal distance, NA is the numerical aperture, and lopt is a spacing between an origin point of the diversing light beam and an end surface of the spherical lens.
In accordance with another aspect of the present invention, a collimating optical system for collimating the diverging light beam has a plane-parallel plate and a spherical lens arranged in this order following to an origin point of the diverging light beam and meets the following relation. ##EQU2## where n is a refractive index of the spherical lens, f is a focal distance, NA is the numerical aperture, nt is a refractive index of the plane-parallel plate, t is a thickness thereof, and lopt is a spacing between the origin point of diverging light beam and an end surface of the spherical lens.
