Our unique diamond turning capability extends to nearly every material that transmits in the infrared, including standard IR materials like silicon, germanium and zinc selenide. ISP Optics also works with not so common materials like chalcogenide glasses such as IG6 or Amtir. Even various plastics like PMMA or Zeonex are diamond turned at ISP. KRS-5 and CdTe aspheres are manufactured using specially developed processes and techniques along with dedicated safety equipment. ISP Optics also works with non-ferrous metals such as nickel plated substrates, aluminum and copper parts to make high quality mirror surfaces Capabilities Aspheres, Aspheres from 0.15 meter - 2.5 meter diameters , Assembly, Beam Splitters, Coating, Component Manufacturer, Conventional Optical Processing , High Laser Damage Threshold Optics, IR Optics, Lenses, Lightweighted Optics, Micro-Optics, Optical Coatings, Optical Design, Optical Subassemblies, Precision Glass Molding, Precision Zoom Optics, Prisms & Flats to Prisms & Wedges, Single-Pint Diamond Turning, Thin & Thick Film Coatings, Windows

The estimate of the root-mean-square roughness of a rough surface σ1 is studied experimentally as a function of the angle of incidence. A surface with σ=1.3 μm is illuminated by laser radiation with a wavelength of 0.633 μm. The angle of incidence of radiation on the surface under study is varied from 85° to 87.5°. σ1 is estimated under the assumption that the regime of a slightly rough surface is fulfilled for the surface studied. Theoretical estimates of σ1 are calculated in the Kirchhoff approximation with rough surface shadowing taken into account. The greatest relative difference between experimental and theoretical estimates of σ 1 does not exceed 0.07. The effect of rough surface shadowing on the estimate of σ is analyzed, and the possibility for exact measurement of σ1 of a shaded rough surface is demonstrated in the case of a priori knowledge of the angle of incidence, for which this measurement is possible. A method that makes it possible to determine the angle of incidence, for which a good agreement between the measured value and the true value of σ of a shaded rough surface is possible, is proposed.
