Manual Upper Zoom Module for 12.5X Zoom Lens

Type:

Zoom Lens, Modular

Regulatory Compliance

RoHS:

Not Compliant

Product Family Description

Compatible with Nikon and Mitutoyo Objectives
High Resolution (FOV range from 0.24 to 45.3mm)
Optional Reticle Projection Attachment

The 12.5X Precision Zoom Lens is beneficial to biomedical, semiconductor, telecom and other microscopy-oriented industries due to its versatility. The optical design is modular and uses large image numerical apertures to yield high-resolution images in a variety of lens configurations. The lens can accommodates camera sensors up to 2/3" format.

A complete optical system requires a TV Tube, a manual upper zoom module and a lower module. Auxiliary lenses can be added to the lower module for easy adjustment of working distance and field of view as applications require. For high magnification inspection, the 12.5X Precision Zoom can be used with Mitutoyo and Nikon objectives (adapter available).

The coaxial lower module kit consists of a fine focus coaxial module, a coaxial coupler, a 40" fiber optic light guide and an appropriate fiber optic adapter. An optional ring light adapter (#89-922) offers an in-line illumination alternative when coaxial illumination is not suitable for the intended application. The reticle projection accessory (#59-682) removes the need for additional electronics that employ crosshairs, circle patterns or other target types for inspection measurements. The reticle projection head accepts all 21mm diameter transmission reticles.
