WIDE FIELD-OF-VIEW ZOOM OPTICS EMPLOYING HYBRID LENS

摘要

PURPOSE: A wide field-of-view zoom optics employing hybrid lens is provided to reduce the number of the comprising lenses using the hybrid lens. CONSTITUTION: The first lens group(100-1) has the minus reflection index. The first lens group is composed of the lens of 3. The second lens group(200-1) has the plus reflection index. The third lens group(300-1) has the plus refraction index. At least one among the sub lenses of the first lens group is the hybrid lens.
