The PriorSpec II is a compact, portable fiber optic inspection microscope designed specifically for the inspection of optical fiber connectors in the field. This high quality inspection microscope is available in 200X or 400X models and incorporates a precision adjustable centering mechanism which permits scrolling of the fiber end face and the ability to view and analyze multiple fibers. The 'folded beam' optical system consists of all glass optics including an achromatic objective and widefield eyepiece for a high quality optical image. In addition, a laser barrier filter is built directly into the unit for safety. Utilizing an universal adapter mount, the PriorSpec II can accommodate virtually any fiber connector. The PriorSpec II incorporates a new and innovative LED illumination system with microprocessor control which provides constant illumination, resulting in an extended battery life and improved light quality. A longer battery life plus a low battery warning display means far fewer battery changes and less downtime. The advanced LED system allows the PriorSpec II to accept re-chargeable 'AA' batteries.
