Introduction The Detector Volume object in Zemax is a very useful tool for detecting light inside a volume. It uses volume pixels, or voxels, to detect light. However, the Zemax interface currently allows these voxels to be viewed only in 2-D planes. This article will sho...

Introduction Veiling glare is a term that is often used in the field of imaging system design. Technically, veiling glare is stray light that reaches the sensor plane of an imaging system, and it can cause a decrease in the imaging system’s performance. There are many pot...

Introduction Accurate simulation and modeling of the human eye can be tricky. Entire volumes have been written on the subject, and it is a subject that continues to spur new developments. In this study, we will create model of a human eye in OpticStudio using the Liou & Br...

Introduction Total Internal Reflection (TIR) is a phenomenon where a light ray is caused to reflect completely (100% reflection) when the light ray is traveling inside a higher-index medium and strikes a surface boundary into a lower-index medium.  When the light strikes ...

Introduction When designing systems using OAPs, it can be helpful to keep the parent parabola in mind, and it can also be helpful to keep the parent parabola in your system, only trimming down to the decentered (or so-called “off-axis”) aperture at the very last step in t...

Introduction Binary optics or kinoforms have small grooves across the optical surface which impart a phase change on the incident wavefront. Zemax OpticStudio does not model the wavelength-scale grooves directly. For detailed information on how diffractive surfaces are mode...

Introduction Off-axis ellipsoidal mirrors (OAEs) are often used to bring a diverging beam from one focus point to another focus point at a 90 degree angle for the Fourier Transform Infrared (FTIR) spectrometer applications. However, OAEs may also be used in visual spectrome...

Definition of Radiant Intensity   Question: The Help file defines Radiant Intensity as “The incoherent intensity of the ray in cosine space (Radiant Intensity) This is the sum of the ray intensity divided by the solid angle subtended by the pixel." The question I have is ho...
