“…This challenge becomes amplified when scaling down to smaller and lighter retroreflectors that can have reduced contact area between mirrors, in contrast to difficulties encountered when scaling up the size of prisms. 12 References that discuss solid prism fabrication 13 mention solid retroreflectors as master cubes for hollow retroreflectors, but a detailed description of hollow trihedral (corner cube) retroreflector fabrication 11,14 is rare; in particular, critical bonding materials are usually omitted as proprietary. 10,[15][16][17] One route involves assembly of coated mirrors in a permanent support structure followed by measurement and adjustment while bonding and curing; 16,17 the other involves assembly and direct bonding of uncoated mirrors on a master prism, followed by coating.…”

Abstract. Hollow rooftop mirrors, also known as dihedral retroreflectors, can simultaneously preserve polarization, minimize chromatic dispersion, and allow beams to be stacked inside an interferometer. Two hollow rooftop mirrors were fabricated and characterized using a Fizeau interferometer and an inexpensive home-built jig instead of a master cube. The mass was 3.3 g for a clear aperture surface area of 110 mm 2 with maximum retroreflected beam deviation of 12 arc s. With a hollow rooftop mirror mounted on a piezoelectric transducer in one arm of a Mach-Zehnder interferometer, a displacement stability of AE0.8 nm rms was achieved using active feedback. The rooftop mirrors' suitability for Fourier transform spectroscopy was demonstrated.

What we believe to be a new technique for the fabrication of a penta prism (PP) with high accuracy right angle deviation of the incident beam is presented. We derive simple formulas relating to the error in right angle deviation with the errors in 45 degrees (beta) and 90 degrees (delta) angles of a PP, and we determine error in right angle deviation from the angle ((error in right angle deviation)r) between the plane wavefronts reflected from the right angled surfaces (external Fresnel reflection on the entrance surface and internal Fresnel reflection on the exit surface) of a PP and the angular error (delta) between the same surfaces. The error in right angle deviation is determined from the measurement of (error in right angle deviation)r using an autocollimator and a Fizeau interferometer, and error in right angle deviation is corrected to a high order of accuracy during the final stage of polishing one of the slanted surfaces of the PP. A new technique to determine the magnitude and direction of the small values of (error in right angle deviation)r is proposed and verified. The result for a PP is presented.
