A practical introductory guide to optical design covering geometrical optics, simple wave-optics and diffraction, using Excel software

- explains practical calculation methods for designing optical systems with fully worked-out examples and avoiding complex mathematical methods
- includes practical calculations for ray tracing, laser beam (Gaussian beam) focusing, and diffraction calculations; the ray tracing and the diffraction calculations are done by using the VBA program which Excel provides as a supporting tool
- describes basic optical theory and application...
