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.

How To Calculate the Sag Profile of a Binary2 Surface Using MATLAB

This article describes how to use the Zemax DDE Toolbox with MATLAB to calculate the sag profile for Binary2 surface. The two MATLAB files BinarySag.m (actual code) and BinarySag.fig (GUI) can be downloaded at the end of the article. More information on diffractive surfaces can be found in the article How to Design Diffractive Optics Using the Binary 2 Surface and How Diffractive Surfaces are Modeled in Zemax.

How to design a confocal fluorescent microscope in Zemax OpticStudio

This articled shows how to design a confocal fluorescent microscope in Zemax OpticStudio using a combination of the Sequential and Non-Sequential modes. The system is designed in two major parts: laser focusing (and collimating) system to the microscope objective, and microscope objective to the tube lens and detector.

Understanding the Geometry in OpticStudio Curvature Cross-Section Analysis

This article explains the geometry behind the OpticStudio curvature cross-section analysis. Two important aspects to understand are

  • the conventions used for the tangential and sagittal curvature directions, and
  • the placement of the cross-section in situations where the aperture is decentered.
A point of possible confusion is clarified for situations when the surface is not rotationally symmetric and the tangential and sagittal curvature becomes multi-valued at the surface vertex due to the arbitrary choice of the tangential direction at that point.
