The aimof the SPIE Field Guides is to distill this information,providing readers with a handy desk or briefcase refer-ence that provides basic, essential information about op-tical principles, techniques, or phenomena, including def-initions and descriptions, key equations, illustrations, ap-plication examples, design considerations, and additionalresources. p. cm.

Greivenkamp, Series Editor Bellingham, Washington USA Library of Congress Cataloging-in-Publication Data Schwertz, Katie M. Field guide to optomechanical design and analysis / Katie M. Schwertz, Jim H. Burge. In mostcases, this modular approach places a single topic on apage, and provides full coverage of that topic on that page.Highlights, insights, and rules of thumb are displayed insidebars to the main text.

The book begins with an outline of the general process before delving into aberrations, basic lens design forms, and optimization.

Also, the two-volume set Opto-Mechanical Systems Design, 4 th Ed., by Yoder and Vukobratovich (CRC Press, 2015), is strongly recommended. • Vukobratovich, D. and S. Introduction to Opto-Mechanical Design will be handed out on CD. I. Burge, James H. II. Much ofthe subject matter and many of the designs are derivedfrom the work of Paul Yoder and Dan Vukobratovich; theirfeedback is greatly appreciated.Image Motion and Orientation 1Optical Effects of Mechanical Motion 1Lens and Mirror Motion 2Plane Parallel Plate 3General Image-Motion Equations 4Image Motion Example 5Rigid Body Rotation 6Quantifying Pointing Error 7Image Orientation 8Mirror Matrices 10Mirror Rotation Matrices 12Cone Intersecting a Plane 13Stress, Strain, and Material Strength 14Stress and Strain 14Strain-vs-Stress Curve 16Safety Factor 17Glass Strength 18Stress Birefringence 20Precision Positioning 22Kinematic Constraint 22Example Constraints and Degrees of Freedom 23Semi-Kinematic Design 24Issues with Point Contacts 25Precision Motion 27Stage Terminology 28Linear Stages 29Rotation and Tilt Stages 30Errors in Stage Motion 31Precision Fastening and Adjustments 32Standard Hardware 32Example Screws 33Fastener Strength 34Tightening Torque 36Adjusters 37Differential Screws and Shims 38Liquid Pinning 39Electronic Drivers 40Flexures 41Stiffness Relations for Single-Strip Flexures 42Parallel Leaf Strip Flexures 43Stiffness Relations for Parallel Leaf StripFlexures 44Notch Hinge Flexures 45Adhesives 46Adhesive Properties 47Adhesive Thickness and Shape Factor 48Thermal Stress 49Choice of Bond Size and Thickness 50Mounting of Optical Components 51Lens Mounts: Off the Shelf 51Lens Mounting: Custom 53Calculating Torque and Clearance 54Potting a Lens with Adhesive 55Clamped Flange Mount 56Lens Barrel Assemblies 57Lens Barrel Assembly Types 58SurfaceContact Interfaces 60Prism Types 62Image-Rotation Prisms 64Image-Erection Prisms 65Prism and Beamsplitter Mounting 66Thin-Wedge Systems 68Window Mounting 69Domes 72Dome Strength 73Small-Mirror Mounts: Off the Shelf 74Small-Mirror Mounts: Adhesives andClamping 75Small-Mirror Mounts: Tangent Flexure andHub 76Mirror Substrates 77Mirror Substrate Examples 79Large-Mirror Mounting: Lateral Supports 80Large-Mirror Mounting: Point Supports 81Large-Mirror Mounting: Active Supports 82Self-Weight Deflection: General 83Self-Weight Deflection: Thin Plates 84Self-Weight Deflection: Parametric Model 85Lightweighting Mirrors 86Flexural Rigidity of Lightweighted Mirrors 88Design Considerations and Analysis 89RMS, PV, and Slope Specifications 89Finite Element Analysis 90Vibration 94Damping Factor 95Isolation 96System Acceleration and Displacement 97Thermal Effects 98Heat Flow 100Air Index of Refraction 102Athermalization 103Passive Athermalization 104Active Athermalization 105Determining Thermally Induced Stress 106Alignment 107Optical and Mechanical Axis of a Lens 108Alignment Tools 109Tolerancing 110Geometric Dimensioning and Tolerancing 110GD&T Terminology 111GD&T Symbology 112ISO 10110 Standard 113Appendices 114Tolerance Guides 114Clean-Room Classifications 117Shipping Environments: Vibration 119Shipping Environments: Drop Heights 120Unit Conversions 121Cost and Performance Tradeoffs for LinearStages 122Torque Charts 125Adhesive Properties 127Glass Properties 130Metal Properties 134Equation Summary 136Glossary 141Bibliography 144References 148Index 149%TMC Percent total mass lost%CVCM Percent collected volatile condensablemateriala AccelerationA AreaCAD Computer-aided designCOTS Commercial off-the-shelfCp Specific heat capacityCTE Coefficient of thermal expansionCVD Chemical vapor depositiond Displacementd DistanceD DiameterD Thermal diffusivityD flexural rigidityE Youngs modulusf Focal lengthF Force, loadf0 Natural frequency (Hz)FEA Finite element analysisFEM Finite element methodg Gravity (9.8 m/s2)G Shear modulusGD&T Geometric dimensioning and tolerancingh Height, thicknessIR Infraredk StiffnessK Bulk modulusKc Fracture toughnessKs Stress optic coefficientl LengthL LengthLMC Least material conditionLOS Line of sightm Magnificationm MassMMC Maximum material conditionMoS Margin of safetyn Index of refractionN A Numerical apertureNIST National Institute of Standards andOPD Optical path differenceP Preloadp PressurePEL Precision elastic limitppm Parts per million (1106)PSD Power spectral densitypsi Pounds per square inchPV Peak to valleyQ Heat fluxr Radius (distance, i.e., 0.5D)R Radius (of curvature)RSS Root sum squareRTV Room-temperature vulcanizationt ThicknessT TemperatureUTS Unified thread standardUV Ultravioletx, y, z Distances in the x, y, or z axis Coefficient of thermal expansion Therm-op
