Condensing and collecting optical system using parabolic reflectors or a corresponding ellipsoid/hyperboloid pair of reflectors

摘要

An optical device comprising:- a source of electromagnetic radiation (20) located proximate to a focal point (36) of a collimating reflector (30);- a target (60) to be illuminated with at least a portion of the electromagnetic radiation emitted by said source,- a focusing reflector (40) comprising at least a portion (42, 44) of a paraboloid of revolution, said focusing reflector (40) being positioned and oriented with respect to said collimating reflector (30) so that the collimated rays of radiation reflected from said collimating reflector (30) are focused substantially toward a target (60),- the collimating reflector (30) and the focusing reflector (40) comprising having a portion (32, 34, 42, 44) of a substantial paraboloid of revolution and having about the same size and shape, with the collimating reflector (30) and focusing reflector (40) having a corresponding size and optical orientation with respect to each other.
