An optical H-K9L roof prism features a precise 90° roof angle configuration to achieve exact 90-degree beam deviation with image inversion. This precision design utilizes two orthogonal reflecting faces to flip images laterally around the roof axis, ensuring critical orientation alignment in compact optical systems. Engineered with a λ/10 surface figure and ±3 arcsecond angle tolerance, these components deliver distortion-free performance across aperture diameters ranging from 9mm to 29mm.
