## How to model diffractive optics using the Binary 2 surface

Diffractive elements are commonly used in optical systems, and their implementation in OpticStudio Sequential Mode is important to understand for many optical designers. This article explains how diffractive surfaces are modeled in OpticStudio, and includes a demonstration of using the Binary 2 surface type to model a diffractive optical element. A sample file is included along with the example.

## Understanding paraxial ray tracing

Paraxial rays and parabasal rays are often used in OpticStudio to calculate system data and analysis results. It is important to understand what these rays are in order to avoid confusion in analysis results. This article discusses these special rays and how they differ from each other and from real rays.

## How to Model Corner-Cube Retroreflectors

Corner Cube retroreflectors are commonly used in a wide range of optical systems. This article describes various different ways in which these components can be modeled in Zemax OpticStudio. The treatment can be as detailed as the user needs, with effects due to face misalignment, roofline straddling, thin-film coatings, diffraction etc included as required.
