Optimizing for MTF Performance using Contrast Optimization

Our new Contrast Optimization technique allows for robust and efficient optimization on the system MTF at a given spatial frequency. The method minimizes the wavefront differences between pairs of rays separated by a pupil shift corresponding to the targeted spatial frequency, which maximizes the MTF. Further computational efficiency is achieved by using Gaussian Quadrature to determine the pattern of rays sampled. Examples are given to demonstrate the advantages of the technique.

Modeling Optics with Realistic Edge Apertures

OpticStudio 16 offers a comprehensive way to model realistic lens apertures with opto-mechanical semi-diameters. Three separate apertures (semi-diameter, chip zone, and mechanical semi-diameter) offer the ability to define a lens component the same way it is made.

Designing a head-mounted display (HMD) for augmented reality systems in Zemax OpticStudio

Augmented reality systems provide good demonstrations of multiple ray paths and free-form optics. This article demonstrates how to set up an optical system for a HMD in Sequential Mode, using a wedge-shaped prism and freeform surfaces.

How To Optimize for Worst-Case Performance

In most cases, we want to optimize for best performance over some average of the field of view or wavelength range of a system. In some cases, its useful to optimize only the worse-case scenario. This is easy to do, and this article describes how.

How to Constrain the Thickness of Aspheric Components

This article explains:
  • Why default thickness boundary constraints are not always sufficient when optimizing aspheric components
  • How the FTGT and FTLT optimization operands can be used to successfully constrain the thickness of a surface at intermediate aperture locations

How To Modify Field Data in the Merit Function Editor Using the FDMO Operand

Although only 12 field points can be defined in the Field dialog, the FMDO optimization operand allows these points to be re-defined on the fly during optimization. This means that any operand that uses a field number as an argument can be computed anywhere in the field of view. This article explains how to use this powerful capability.
