  1. 1. Optical CAD Tools -An Introduction Samuel Cherukutty C 208114018 M.Tech
  2. 2. What is in this ??? What is CAD Why go for CAD tools What are the Different Propagation Models in Optical CAD Classification of CAD tools The different CAD Tools Conlusion
  3. 3. What is CAD??? Computer Aided Design (CAD) is the use of computer systems to assist in the creation, modification, analysis, or optimization of a design
  4. 4. Why go for CAD tools????? Reduces human error Availability of standard devices in library Easier and cheaper to modify designs Direct linking with Computer Aided Manufacture(CAM) is possible Simulation helps in detecting and correcting errors before implementation
  5. 5. What are the Different Propagation Models in Optical CAD??? Ray Propagation - Direction, position and angles Gaussian Propagation - 9 scalar parameters(z0,x,y,z,etc..) - Fast simulation (no integration) - Limited diffraction modeling Scalar Optics - 2D complex wave front - Propagation by summation of wave fronts Vector Analysis - Intensive computation, Boundary Element
  6. 6. How can I classify CAD tools available for optics??? Lens/Component Design Software Laser and Integrated Optics Design Software Thin Film Design Software Illumination and Straylight Software Testing Software Optical Signal Simulation Softwares
