Introduction Many surfaces in OpticStudio can have diffractive power in addition to refractive power. Diffractive power is independent of the index and the surface sag and changes the  phase  of the rays. For more information on how diffractive surfaces are modeled in Opt...

Introduction Fresnel lenses break a normal lens into a set of concentric annular sections known as Fresnel zones.   Fresnel lenses are lighter and occupy a smaller volume than the equivalent spherical lens. Fresnel lenses are used in  lighthouse projectors , rear-p...

Introduction This article describes work undertaken at the University of Bern to model the cavity of a side-pumped crystal laser. The radiation transferred from the pumping diode array to the laser rod was modeled using the non-sequential mode of Zemax. The absorbed flux ...

How Photoreceptor Cells Function The cells in the human eye have different strengths of sensitivity to different wavelengths of light, which is referred to as the luminosity factor. The photoreceptor cells in the retina are composed of two types of cells, rod cells and cone...

Introduction There are two distinct ray tracing modes supported by Zemax OpticStudio (Sequential and Non-Sequential), but often times it is necessary to combine the two techniques.   A design which uses both methods of ray tracing is often referred to as a “mixed-mode” sys...

Introduction The BSDF Data Interchange file format was developed here at Radiant Zemax, LLC (RZ).  It is designed to be a compact, simple way to transfer BSDF data.  Specifically, as the Imaging Sphere for Scatter and Appearance (IS-SA) developed by Radiant Zemax can ...

Introduction If a glass or material you wish to use in your design does not currently exist in the OpticStudio Glass Catalog, there are various methods available to create this glass in OpticStudio. One of these methods includes what is called a model glass. Basically, t...
