EUV And the State of Lithography
High-End Optical Lithography, what’s it all about EUV lithography feels like science fiction made real: mirrors with atom-level smoothness, light generated from tin plasma, and machines that cost more than a fleet of private jets — all to etch nanometer wide features onto silicon. And yet, for all its technical audacity, EUV is still a…

Physical Optics On the Nvidia GPU
Intro For most of my career in optics, I have been simulating imaging of spatial light modulators, and mostly, SLMs illuminated with partially coherent sources. Usually, the FFT makes a fairly swift job of it, for a single image at least. Sometimes, though, One needs to do a lot of simulations. One such example is…

Distortion Mapping – An SVD HowTo
In this tech-talk, I would like to discuss how (and probably how not to) develop an optical distortion correction. It is a common optical problem, and one that actually can be compensated using an algorithm because, even if the image is distorted, it can still be free from wavefront aberrations. I guess the title spills…

Senslogic – Unleash the Power of the Cross-Over Expert
Why choose Senslogic? A very reasonable question indeed. There is no shortage of established companies offering customized services that can handle solutions which include software, hardware and optics. Senslogic is but one and much less known. We offer low overhead for projects that typically require a multidisciplinary team. Let me also explain why Senslogic offers…

HowTo: Spatial Light Modulators
About This Tech-Talk Spatial light modulators (SLMs) are active optical components that can alter a light beam’s amplitude, phase, or polarization. For this tech-talk, I’ll focus on a specific subset: those that achieve this using a pixelated, two-dimensional array. While this doesn’t cover all types of SLMs, it’s a sufficiently large and interesting category to…
