GMH19 K9 Hollow Right-Angle Reflecting Prisms
From $500 USD
Request a quoteProduct description
GMH19 hollow right-angle mirror assemblies combine two first-surface right-angle reflectors fixed to a glass base. The category specifies a 90° ±10 arcsec angle between the reflecting faces and describes the hollow path as avoiding refraction, dispersion and material absorption.
The four listed models share a stated size of 25.4 ×25.4 ×19 mm and a 90° ±10 arcsec dihedral angle. Each model record identifies its own protected UV-reflective aluminum, enhanced protected aluminum, protected silver or protected gold coating.
The category lists reflected wavefront distortion of λ/2 at 633 nm, clear aperture above 90%, 40-20 surface quality and a damage threshold above 1 J/cm² at 1064 nm under 20 ns, 20 Hz conditions. These are category specifications; coating choice is model-specific.
GMH19 original optical ray schematic
Original source reference drawing; obtain a model-specific manufacturing drawing before integration.
The source identifies optical delay lines and interferometric measurements as applications and marks drawings as references that may differ from delivered products. Category material is listed as fine-annealed H-K9L glass, while all four model records say K9; confirm the material declaration for the selected model.
