WIDE ANGLE LENSE SYSTEM

摘要

PURPOSE: An optical angle lens system is provided to realize ultra wide angel high definition by observing a total constant space by using one camera. CONSTITUTION: A first lens(10) refracts or reflects the light emitted from an object. A first refraction surface refracts the light emitted from the object. A second lens(20) refracts the light emitted from the first lens. A iris diaphragm(30) is installed to rear direction of the second lens. A third lens refracts the light which passed through a iris diaphragm.
