OPTICAL COMPONENTS Spherical Lenses Cylindrical Lenses Lens Kits Achromatic Doublets Multi-Element Micro Optics Hollow Retro-reflectors Hollow Retro-reflectors consists of three flat mirrors assembled to reflect the input beam by 180 degrees. Unlike the solid corner cubes, the entire optical path is in air and as a result can be used as a broadband reflector. Additionally, because the hollow retro-reflector is configured with only front surface mirrors, the design reduces the affects of polarization and chromatic aberration. The precision assemble of the flat mirrors in the hollow retro-reflectors insure highly accurate beam deviation. Each retro-reflector is assembled in a black anodized aluminum mount. These "angle insensitive" mirrors have numerous uses in alignment and metrology. Our retro-reflectors come standard with protective aluminum for use in the visible spectral region.
