Abstract: This invention relates to an optical module for coupling an optically operative device with an optical fiber. Near the optically operative device, the module includes a fiber saddle on which the optical fiber is affixed by soldering to optically connect the operative device and the fiber. The fiber saddle is provided on a heat insulative substrate, which also mounts the optically operative device, so that heat for melting the solder will not be conducted through the fiber saddle when the optical fiber is soldered to the saddle. Thus, the temperature necessary for soldering can be attained rapidly. A mounting surface of the fiber saddle is plated with solder. A pre-formed solder structure is bridged over the optical fiber after it is positioned on the fixation surface. The pre-formed structure is melted and then allowed to solidify whereby the optical fiber is affixed to the fiber saddle to prevent dislocation of the fiber.

Abstract: A front zoom system and a rear zoom system are coupled in said order from an object side, wherein said rear zoom system comprises a fixed positive lens group, a negative compensator lens group in which its first plane has its convex plane facing an object side and its last plane has its concave plane facing an image side, a negative variator lens group in which the lens group itself is virtually achromated, and a fixed relay lens group, being positioned in the order given from an object side. While the magnification variation range is enlarged by consecutively performing the zooming operation of the front zoom system and the zooming operation of the rear zoom system, aberrations at that time are satisfactorily corrected. The focal distance of the variator lens group is made short in comparison with that of the compensator lens group, thus the amount of shifting of this lens group is reduced for making the rear zoom system compact.
