Title: Front teleconverter
Inventor: SATO HIROSHI
IPC: G02B15/10
Filed: 1990-11-27
Abstract: PURPOSE:To compact a front teleconverter and correct each aberration by forming a first lens group of two pieces of positive meniscus lenses with their convex surfaces facing the side of an object, and forming a second lens group of a piece of a negative meniscus lens with its convex surface facing the side of the object. CONSTITUTION:It is desirable to satisfy each condition of a formula I to compact a front teleconverter as well as favorably correcting various aberration. A condition (1) is a fundamental condition to constitute the teleconverter while carrying out thorough aberration correction. If the upper limit of this condition is exceeded, not only the first lens group but also the second lens group become weak in their aberration strength and longer in their length, and their compactness is spoiled. When the lower limit is exceeded, astigmatism becomes larger and a tangential image surface becomes larger and be apt to fall under. Consequently, it is possible to especially restrain astigmatism while keeping the overall length short to the utmost by properly carrying out bending of each lens.
