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 free from wavefront aberrations. I guess the title spills the…

The Challenge of Simplifying Precision
Introduction This tech-talk is about why simple isn’t always easy and what the Shack-Hartmann (SH) module in WaveMe must do to make life easy for you. In an earlier tech-talk, we elaborated on the calibration of SH sensors in general and, in the end, how and why we choose to do things differently in the…

When Optics Met WaveMe
Much like “When Harry Met Sally”, discovering the depths of their relationship over time, integrating WaveMe into your lab toolbox is an evolving partnership that blossoms with investment and effort. At first maybe you noticed how simple and effortless WaveMe’s wavefront sensing was, but the real magic unfolds as you dive deeper, taking advantage of…

Shack-Hartmann Wavefront Sensor Calibration in WaveMe
Calibration and Why it is Needed The WaveMe toolbox has a rather exceptional calibration method that allows for much more flexible use of the Shack-Hartmann wavefront sensor. This tech talk will be about what it is and why it is different from what is available elsewhere. We will assume that you, the reader, are already…

Analyzing Coupled Systems
Designing new optical systems from the ground up can be an intimidating task, especially if the system we are trying to make is one that we must get right before anything can be built because the critical components simply do not yet exist. It’s merely a figment of our imagination and it is actually part…

WaveMe for Optical Alignment: The BeamNotes Tool
Introduction In the realm of optical engineering, achieving precise alignment between the optical elements within a system is crucial to ensuring optimal performance. This alignment is especially critical in compact optical systems like microscope lenses or other high-end optics. There are some well known brands here like Zeiss, Leica, Nikon or Tropel. They know what…
