Features

Retroreflector Stability

Our broadband hollow retroreflectors are constructed of three front-surface flat mirrors assembled into a corner cube. A stress-free mounting technique is employed to ensure dimensional stability. This geometry results in a reflected beam that is precisely parallel to the incident beam, independent of the angle of incidence.

Comparison with Glass Retroreflectors

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, parallelism up to 1 arc sec and wavefront distortion ≤λ/3 is economically achieved. These retroreflectors are offered in 25.4 or 63.5 mm diameter apertures and 5, 2, or 1 arc sec parallelism. Coatings are available for the UV, visible, and infrared, with damage threshold typically 100 W/cm2 CW or 10 mJ/cm2 with 10 nsec pulses. The rugged aluminum and plastic housing is compatible with Newport mounts and components. Each unit has a back plate with an array of holes to accommodate various mounting requirements.

UV Enhanced Aluminum Coating - 225 to 700 nm

Protected Aluminum Coating - 400 to 700 nm

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.
