Introduction Optimization of glasses is handled somewhat differently than other data. Optimizing the glass choice directly is a difficult and unpredictable process because there does not exist a continuum of glasses on the glass map. For example, a thickness can be eas...

Introduction The Source File object can be used to directly specify the coordinates, cosines, intensities and (optionally) wavelengths for a set of source rays in non-sequential mode. LEDs and other complex sources are most acccurately modeled with the Source File object. ...

Introduction   The Henyey-Greenstein model describes the angular distribution of light scattered by small particles. This model has been applied to numerous situations, ranging from the scattering of light by biological tissue 1 to scattering by interstellar dust clouds ...

Introduction Many lighting applications involve the use of multiple sources for generating a particular color output in the far-field. The spectral distribution for each of the sources may be simple (e.g. monochromatic) or complex. The traditional approach for simulating ...

Modeling Photoluminescence in OpticStudio: A Photoluminescent Solar Concentrator   Introduction Photoluminescence is the absorption and emission of photons through a process of photo-excitation and radiative relaxation. The effect can be simulated in OpticStudio throug...

Introduction Tolerancing is the process by which the effects of manufacturing defects and alignment errors are considered. This article is an overview of the entire process, and is intended to be the first article a new user would read to start to understand the process. O...

Introduction ZDC thanks Steve Dods of OptiWave Corporation for supplying the SMF-28 fiber simulation data used in this article. In the article How to Model Coupling Between Single-Mode Fibers SMF-28 single mode fiber is modeled using data from the manufacturer's data...

Introduction Manufacturers will often provide discrete refractive index data for a glass, i.e. index as a function of wavelength and temperature. This data may be used to define a new glass in Zemax. If the refractive index of the glass exhibits no temperature variat...

Introduction There are a number of analysis features in Zemax which use IMA and/or BIM files to provide a description of an extended source in sequential mode. Files have been provided which describe a variety of illumination patterns, such as a circle, a square, a grid, ...

Introduction Surface scattering is an important effect to consider when analyzing both the illumination and stray light characteristics of a system. In many cases scattering is a desired effect. Analytic scattering distributions which are built into OpticStudio include t...
