One of the most powerful features of Zemax is its open architecture, which allows the motivated user to create custom sources to match the physical properties of the problem at hand.  Although Zemax comes with an impressive suite of primitive sources (particularly in non-seq...

INTRODUCTION Zemax supports two types of array objects in non-sequential mode: the array and array ring. Both objects are used to replicate any geometric parent object quickly and efficiently. The standard array object is used for modeling rectilinear arrays, with element...

The Normalization Radius Most diffractive surfaces, like the Zernike surfaces or Binary Optic surface, express the phase added by the diffractive using some equation that uses a normalized distance parameter r. For example, the Binary Optic 2 surface adds phase using the ...

What is the RAYLIST? The normalized field and pupil coordinates (Hx, Hy, Px and Py respectively) of a ray are often used to indicate to Zemax OpticStudio exactly which ray is desired for analysis. For example, the Single Ray Trace calculation (via The Analyze Tab > Image Q...

Introduction Zemax LLC thanks Dr. Brian Bauman of Lawrence Livermore National Laboratory for his guidance in the development of this feature. The ability to efficiently calculate root-mean-square (RMS) spot size and wavefront error in an optical system is of critical imp...

What is Birefringence? Normal glasses are homogeneous and isotropic, that is, they have the same refractive index no matter what direction light travels through them. Uniaxial materials, such as Calcite, have a crystal axis which defines an axis of symmetry. These materia...

Introduction Vignetting describes the effects by which the brightness of an image is reduced at its edge relative to its center: http://en.wikipedia.org/wiki/Vignetting In many optical systems, surface apertures can cause the input beam to be vignetted. Vignetting ca...

What is a ray? Rays are used to model the propagation of light through optical systems. For homogeneous, isotropic media, such as common optical glass, rays are straight lines. Rays are normal to the local wavefront and point along the direction of energy flow. Rays have p...

Introduction There are many fabrication and mounting errors to consider when tolerancing an optical system. Zemax OpticStudio’s tolerancing capabilities can model a number of different tolerances, including tolerances on radius, thickness, tilts, and decenters of surfaces or...
