Introduction The Source Diffractive object in non-sequential mode is defined by a collimated ray bundle passing through a user-defined aperture (UDA).  The simulation of this source includes scalar diffractive effects due the clipping of the wavefront by the aperture. Th...

In Zemax OpticStudio, we commonly use Tilt About X/Y/Z to rotate sequential surfaces or non-sequential objects to desired orientation. For example, in sequential mode, we use Tilt About X/Y/Z in Coordinate Break to define the orientation of next surface. And, in Non-seq...

When working with diffractive elements in OpticStudio, it is important to understand how OpticStudio handles diffraction in ray tracing. This article explains how diffractive surfaces are modeled, and the differences between kinoform and binary optics. Zemax Development Co...

Tolerancing using TEZI Tolerancing surface irregularity is difficult because surface irregularity is not deterministic. Often times, the RMS surface error introduced on an optic during manufacturing is specified by the lens supplier by taking the average of RMS surface er...

Introduction The most general description of a complex source is given in a Radiant Source Model (RSMX) file. This file contains the measured radiant or luminous intensity of the source as a function of wavelength, position, and angle. As such, this file can be accurately...

Introduction There are many situations in which it is necessary to know the surface sag of an object in Zemax. This information can be easily obtained in sequential mode using the SAGG operand, or by clicking under Analysis > Surface > Surface Sag . In non-sequential ...

What is Ray Aiming? The Ray Aiming is an iterative ray tracing algorithm in OpticStudio that finds rays at the object that correctly fill the stop surface, for a given stop size. It is generally only required when the pupil, the image of the stop as seen from the object sp...

Introduction Paraxial rays are rays which are traced according to a linear approximation to Snell’s Law, which provides the benefit of greatly improving computational efficiency. In contrast, parabasal rays use the explicit form of Snell’s Law, but make only small angles ...

Introduction When working with a Sequential optical system, we usually work in local coordinates, in which one surface is located a thickness in Z away from the previous surface. Coordinate break surfaces provide decentrations in x and y, as well as tilts in X, Y and Z. A...

A Fresnel lens is a concave or convex lens that has been clasped in the z-direction. The profile is discontinuous and has grooves that minimize its thickness, but it is otherwise identical to a curved surface. Figure 1: A convex lens and an equivalent Fresnel lens.   ...
