Multi-threaded Optimization in Zemax OpticStudio

Zemax OpticStudio is designed to exploit all the CPUs in the user's computer without any user intervention. It will automatically determine the optimum number of threads to launch for any given calculation, including during optimization. One question the engineering team often encounters is why CPU usage seems to be single threaded during optimization. This article specifically addresses that topic.

Interfacing to OpticStudio from Mathematica

This article provides an example of the standalone method, in which the external application is Mathematica. A Mathematica notebook is used as a user interface and scripting language. It will start an OpticStudio session, load an existing lens file, manipulate that lens file to alter the lens design, perform an analyses, and obtain and process the results to provide information not directly available through OpticStudio.

Freeform Optics in OpticStudio

OpticStudio provides a number of tools for the design of Freeform Optics in both sequential and non-sequential modes. In this article, we’ll provide an example of an off-axis parabola using the Chebyshev Polynomial surface in sequential mode. We’ll also describe filtering tools available in the Lens Data Editor that quickly allow you to find the freeform surface of choice for any desired application from the more than 20 such surfaces that are currently supported in sequential mode.

How to Get Real-Time Lens Prototype Costs in OpticStudio

Design for manufacture is a phrase commonly used to describe how manufacturing considerations are incorporated into the optical design process. OpticStudio offers several capabilities that support design for manufacture, and the Cost Estimator allows users to send lens data to manufacturers and get real-time cost estimates.

Overview of Photoluminescence Simulation in OpticStudio

Photoluminescence is the phenomenon where photons are absorbed in a medium and part of the absorbed energy is reemitted as photons. Broadly speaking, there are two categories of photoluminescent emission, fluorescence and phosphorescence. Each of these can be modeled in OpticStudio using the photoluminescence bulk scattering model available in non-sequential mode.

Ophthalmic Lens Design

This article describes the principles of ophthalmic lens design, and discusses the parameters of the lens, the eye and the visual environment that are critical to the lens design. A glass catalog for common ophthalmic lens materials (both glasses and polymers) is included.
The article does not include progressive lens design, although progressive lenses tend to follow the general base curve principles of other ophthalmic lenses, nor does it consider specific purpose lenses such as those intended to reduce the progression of myopia.
