Modeling UV-C Irradiation Chambers for Mask Decontamination using Zemax OpticStudio

Modeling UV-C Irradiation Chambers for Mask Decontamination using Zemax OpticStudio

As pharmaceutical companies around the globe tirelessly work towards a vaccine for COVID-19, it is imperative that we provide hospital staff serving on the frontlines with necessary personal protective equipment (PPE). Unfortunately, as cases of the virus surge around the world, PPE supplies are running short. The ability to properly sterilize masks for re-use will be critical in the coming months, and optics play an important role in this process. Specifically, UV-C lighting can be used inside of appropriately configured decontamination chambers to provide the necessary sterilization.

Leveraging 3D Camera Technology for virtual tours

Leveraging 3D Camera Technology for virtual tours

The COVID-19 pandemic continues to disrupt our normal routines in several ways. One example is how we buy, sell, and rent real estate. When getting ready to buy or rent a home, the ability to walk through the space to understand the layout and flow are important, but during these challenging times on-site visits are often not possible. As a result, virtual tours are becoming more and more popular.

Customer spotlight: Holo/Or achieves realistic beam modeling in Zemax OpticStudio using geometric ray tracing

Customer spotlight: Holo/Or achieves realistic beam modeling in Zemax OpticStudio using geometric ray tracing

A pioneering international optical design company based in Israel, Holo/Or designs and manufactures diffractive optical elements (DOEs) and micro-optical elements used worldwide for sophisticated applications involving high-precision and high-power lasers. Holo/Or was experiencing some challenges in modeling realistic systems for diffraction-limited results. But the company developed an ingenious solution—use of the bidirectional scattering diffusion function (BSDF) to simulate and optimize multi-mode (or single-mode) lasers using geometric ray tracing. As described in their whitepaper, “Method for Laser Source Definition in Zemax,” this approach enables Holo/Or to quickly achieve accurate results for factors like realistic spot-size at lens foci while accounting for wave optics effect and also allowing for simple system optimization.
