Interferometer – or – Wavefront Sensor
Technology continues to advance, and so do wavefront sensors. One notable improvement has been in wavefront sampling density. Examples of such sensors include the HASO LIFT sensors from Imagine Optics and the QWLSI sensor by Phasics. Each uses a different technique to achieve higher sampling density. The LIFT technique—short for Linearized Focal-plane Technique—is a modern…

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…

System Integrator’s Dilemma
This Tech-Talk is about technology development in general, but perhaps more specifically, incremental technology development. It is obviously influenced by my own experience in the optics industry where the optical module is but one component in a larger system combining diverse engineering disciplines ranging from mechanics, optics, mathematics and software. Expectations – make sure to…

Can AI Do Your Code?
I guess I am on a mission, a mission to moderate the awe people seem to be struck with related to AI. Since I’m into optics, I write a lot of code, all sorts of code, and obviously I’m interested to spend as little time as I can doing it. Before I added Zernike plotting…
