Product Family Description

Incident Light is Reflected Back to the Source
Useful for Surveying and Alignment
¼-20 Tapped Holes for Easy Mounting
Also Available Unmounted

TECHSPEC® Mounted N-BK7 Corner Cube Retroreflectors are mounted in an aluminum body and held in place with RTV potting cement. Due to their complex shape, corner cube retroreflectors can often be challenging to mount. These retroflectors provide a convenient and durable solution. TECHSPEC® Mounted N-BK7 Corner Cube Retroreflectors are easily integrated via two ¼-20 tapped holes. In addition, each retroreflector has silvered reflecting surfaces to decrease polarization effects and increase field of view. For dimension details, see the “Technical Information” tab.

Corner cube retroreflectors are designed to reflect any ray or beam entering the prism face, regardless of the prism’s orientation, back onto itself. A mirror will only do that at the normal angle of incidence. As a result, corner cube retroreflectors are ideal where precision alignment is difficult or time-consuming.
