Join Zemax CTO in Celebrating the International Day of Light

Join Zemax CTO in Celebrating the International Day of Light

As we celebrate the International Day of Light, there has never been a better time to recognize the role of optics and photonics in our daily life. Throughout the past year I have highlighted the important contributions of optics and photonics to the life sciences, specifically in the fight against COVID-19. Significant innovations in diagnostic and treatment have been – and will continue to be – driven by light-based tools.

Introducing the OpticStudio STAR Module

Introducing the OpticStudio STAR Module

Zemax is excited to announce the coming launch of our OpticStudio Structural, Thermal, Analysis and Results (STAR) module. Coming in late May 2021, the new OpticStudio STAR module will allow engineers to streamline their workflows by visualizing and analyzing the impact of their structural and thermal factors within OpticStudio. For the first time, users will be able to visualize FEA data from any source natively within OpticStudio.

Introduction to stray light analysis

Introduction to stray light analysis

This blog post introduces how to prepare for stray light analysis by using the Convert to NSC Group tool to convert a sequential system to non-sequential mode.

In photography, a common source of stray light is a vital light source (such as the Sun) outside the field of view. Light from such sources can reach the image plane via scattering from the system's mechanical or optical components. Alternatively, light from a source inside the field of view can undergo multiple secondary reflections at lens surfaces before focused on the image surface.

How to design DOE lens or metalens in OpticStudio

How to design DOE lens or metalens in OpticStudio

Diffractive Optical Elements (DOEs) and Metasurfaces / Metalenses are gaining increasing popularity in optical system design, for applications ranging from cell phone lenses to AR/VR headsets, from 3D sensing to illumination. But simulating and designing for systems that include DOEs or  metalenses are always tricky. There is no generalized method to handle all situations. Designers need to decide the strategy for their systems case by case. Many design processes require two different optical theory/algorithms to separately handle the beam propagation in free space and in microstructure, while others use only pure raytracing to achieve the goal.
