Omni Wave Hollow Retroreflector™ (OWHR)

The Omni Wave Hollow Retroreflector (OWHR) can be described as a self-compensating mirror that is totally insensitive to position and movement such as tilt. Parallel incident light that hits the OWHR will be returned with great accuracy to the light source, regardless of the OWHR’s physical orientation. The OWHR is constructed of three first-surface mirrors assembled by a proprietary process into a mutually-orthogonal inside corner. The mirrors can be coated for maximization over a spectral range, from UV to far IR. This configuration eliminates material absorption and achromatic aberration present in prism-type retroreflectors. OWHRs are available in standard sizes of 0.08 in (2mm) to 5.0 in (l25mm). The units are available in accuracies to 0.5 arc seconds beam deviation and l/10 wave reflected wavefront error. In the new improved configuration, available only from PLX, the OWHR has a unique, patented, cushion mounting, which makes the unit extremely resistant to shock. The OWHR is provided in a versatile housing, which is compatible with all major mounting systems. The OWHR is available with a broad range of standard metallic coatings which meet all applicable MIL-specs. Unprotected metallic coatings are especially suited to interferometric applications. Custom coatings are available upon request.

Choose the coating you need: COATING SPECIFICATION CHART * Beam Deviation is the maximum deviation from parallelism, expressed in seconds of arc, of any single return beam from any of the 6 sub-apertures of the retroreflector, when the retroreflector is fully-illuminated. Exiting Wavefront is the resultant maximum peak-to-valley wavefront deformation from a fully-illuminated retroreflector, where lambda = 633nm. * Certain high-accuracy models may be heavier than indicated here. Check with us for actual weight.
