Corner Cube Retroreflectors

With over 60 years of experience, Precision Optical is the industry leader in manufacturing retroreflectors of many varieties, including:

• Standard corner cubes with sub arc second beam deviation over the full diameter of the clear aperture. Protected metal coatings to reduce phase shifting wavefront aberrations and sharp roof edges, are available upon request.
• Truncated retroreflectors for light-weighting applications and spatial constraints. These prisms have precise beam deviation, transmitted wavefront, and positioning of the theoretical apex to datum surfaces.
• Lateral transfer corner cubes are ideal for applications that require a lateral beam displacement that is much larger than the clear aperture size. One trihedral reflecting face is located at one end of the prism, while the other two trihedral reflecting faces comprise a roof edge at the opposite end.
• Custom hollow retroreflectors are comprised of three reflective mirrored surfaces aligned at 90° to one another. Because the entire optical path is in air, these prisms operate over the greatest angular range while mitigating the aberrations associated with the dispersion of glass. Precision Optical employs a proprietary process to create a monolithic hollow retroreflector, which is ideal for large temperature variations and low pressure environments.
