Introduction, Lens Prescription and Design Constraints The singlet (a single lens) is arguably the simplest imaging system modeled in Zemax OpticStudio. Nevertheless, the design of this simple imaging system can help introduce you to the interface of Zemax OpticStudio...

Introduction Modulation Transfer Function (MTF) is an important method of describing the performance of an optical system. A consequence of applying Fourier theory to image forming optical systems, MTF describes the contrast in the image of a spatial frequency presented i...

Setting Up the Scanning Mirror In this article we will demonstrate how to set up a scanning mirror such that a mirror scans +5° about its nominal position of 90°. The file "starting point.zmx" is in the zip archive you can download from the last page of this article. It sh...

Introduction Usually in OpticStudio we work with parametric models of surfaces and objects, so that (for example) a radius of curvature defines the surface of a lens at any point on its surface. This is both compact and easy to optimize. A 'freeform' surface by distincti...

How to Scale the Weighting for a Range of Optimization Operands Optimization is an interactive process, and often times weightings of operands need to be adjusted to enforce a certain design constraint. In some cases, we may wish to increase or decrease the weighting for ...

Introduction The visual appearance of a diamond is created by the combination of various optical effects: reflection, refraction, scattering, and total internal reflection. Below is the image of a diamond on a true color detector in Zemax. This knowledge base ar...

Introduction The ability to import CAD objects into OpticStudio is very important, particularly when undertaking complex opto-mechanical stray light simulations, where reflections and scattering from mounts is critical. It is also important in illumination system, where l...

Introduction Mie theory (also known as Lorenz-Mie theory or Lorenz-Mie-Debye theory) describes the analytic solution to Maxwell’s equations for scattering of light from spherical particles. The theory allows the size of the particle to be arbitrary, i.e. the solution is appl...

Introduction Light scattered from surfaces can contribute significantly to the image quality and overall performance of an optical system. In many cases scattering is a desired effect, e.g. when a source with uniform angular distribution is created by passing a light be...

INTRODUCTION Zemax has many features that allow the user to visualize an optical system they have designed. From simple two dimensional line drawings to more complex OpenGL shaded model layouts, there are numerous options for displaying a system. For many purposes, these ...
