Introduction For Gaussian beam size measurements, Zemax uses the 1/e^2 half-width point, which means the intensity has fallen to about 13.5% of the peak. However, often times manufacturer’s data sheets provide only Full Width Half Maximum (FWHM) measurements and not 1/e^2...

Introduction The free ‘Express’ edition of Microsoft Visual Studio compiles only to 32-bit code by default. This article describes how to configure Visual Studio Express to compile 64-bit code, as would be required when creating user-defined dlls to run with 64-bit Zemax. ...

Introduction Brightness Enhancement Film (BEF) is widely used in the design and manufacture of LCD screens and large-screen TVs. It is generally used to provide maximum brightness towards the on-axis viewer. BEF uses a microreplicated prismatic structure to control the...

Introduction A number of optical systems (e.g. digital displays and projection systems) require knowledge of the photometric (human eye) response of the system to a broadband source. In Zemax, a polychromatic source may be defined either by using multiple system wavelengt...

Introduction Even though there are 300+ built-in optimization operands, there are cases in which you wish to return and optimize a value that the existing operands do not calculate. For this reason, OpticStudio supports the flexibility of a user defined program for defini...

Introduction In the sequential mode of OpticStudio, the Coordinate Break (CB) surface is used to define a new coordinate system in terms of the current system.  Primarily, these surfaces are used to perform tilts and decenters of surfaces defined in a local coordina...

Introduction Problem: How can we model a linear thermal temperature gradient of an interferometer cavity in Zemax?    This question was posed by an interferometer expert in one of the online optics fourms. He wanted an analytical or modeling solution to this problem....
