• Incident Light is Reflected Back to the Source
• Down to 3 Arcsecond Beam Deviation
• Useful for Surveying and Alignment
TECHSPEC® Corner Cube Retroreflectors are designed
to reflect any ray or beam entering the prism
face, regardless of the orientation of the prism, back
onto itself. A mirror will only do that at the normal angle
of incidence. As a result, corner cube retroreflectors
are useful in surveying, or where precision alignment
is difficult or time-consuming. TECHSPEC®
Corner Cube Retroreflectors are available in two
substrates, either UV Fused Silica, or N-BK7. UV
Fused Silica versions feature excellent transmission
throughout the UV, VIS, and NIR spectral ranges,
and are available uncoated, or with aluminum coated
reflective surfaces. N-BK7 versions are available uncoated,
or with silver coated reflective surfaces and
with either VIS 0° or NIR II BBAR coatings. The
metal coating on the reflective surfaces improves acceptance
angle and removes polarization issues that
occur in uncoated reflecting surfaces at a price of a
small reduction of throughput.

• Incident Light is Reflected Back to the Source
• Ideal for Alignment
• 1/4-20 Tapped Holes for Easy Mounting
Due to their complex shape, corner cube retroreflectors
can often be difficult to mount. Our TECHSPEC®
Mounted N-BK7 Corner Cube Retroreflectors provide
a convenient and durable solution. Mounted in an
aluminum body and held in place with RTV potting
cement, our TECHSPEC® Mounted N-BK7 Corner
Cube Retroreflectors are easily integrated via two
1/4-20 tapped holes. In addition, each retroreflector
has silvered reflecting surfaces to decrease polarization
effects and increase field of view.
