Kinematic Mount Selection for Optical Scanning Assemblies
Kinematic mount selection for optical scanning assemblies isolates substrates from thermal and dynamic distortions while maintaining sub-microradian repeatability.
ISO 10110-5
Meaning
International drawing standards define the symbolic representation and measurement criteria for surface form tolerances in optical components. The standard iso 10110-5 specifies notation for peak-to-valley sag errors, rotational asymmetry, and rms wave-front variations on planar or spherical optical surfaces. The scope of this standard governs optical design drawings and manufacturing documentation, ending where surface texture and localized scratch-dig defects are addressed by separate sub-standards.
Tolerance Code
Numerical code entries on optical fabrication prints communicate maximum permissible peak-to-valley and RMS surface figure errors to polishing technicians. Optical shop floor inspections compare surface departure profiles against design specifications to prevent optical aberrations in assembled lens systems. Initial prototype polishing passes may achieve flat wave-front profiles across small apertures, but scaling to full production lens runs often introduces edge roll-off that violates code tolerances.
Interferometric Measurement
Laser phase-shifting interferometry measures phase map variations against ideal spherical or flat reference surfaces to generate quantitative form error figures. Sub-aperture stitch testing expands inspection capability for high-curvature optics without sacrificing spatial resolution.
Specification Boundary
Standardized callouts exclude mechanical mount interface tolerances which remain governed by separate mechanical drafting codes. Optical fabrication drawings rely on standardized form error notation to ensure unambiguous interpretation between optical designers and manufacturing plants.
