Features

Stable Monolithic Construction

Our replicated hollow metal retroreflectors are monolithic, fabricated from a single piece of aluminum, resulting in return beam accuracy unaffected by vibration. Vibration sensitivity is reduced further by employing an integrated mount in the design.

Gold Coating with High IR Reflectivity

Front surface coated with gold for high reflectivity in the IR and deep IR.

Advantages vs. Glass Retro Reflectors

Unlike solid glass retroreflectors, the optical path is entirely in air so efficient performance is obtained without antireflection coatings which limit the operating wavelength range. Using a novel patented fabrication technique, return beam accuracy as low as 2 arc sec. is economically achieved. These retroreflectors are offered in 12.7, 19.1, 25.4, 38.1, or 63.5 mm diameter and 30, 10, 5, or 2 arc sec return beam accuracy.

Alignment Free 180 Degree Reflection

Retroreflectors, also known as corner cubes as all three mirror surfaces are perpendicular, will reflect all incoming light 180° regardless of incidence angle. This enables 180 degrees reflection of a beam without requiring prior alignment (as with a flat mirror). Images reflected by a corner cube are reversed and inverted.
