8020 Extrusion Optic Sliders
For some time now I’ve been using 8020 extrusion for quick prototyping of optical assemblies. It’s great for assemblies which require longer focal lengths and larger elements. For such systems, the choices are to use a breadboard or table, with posts – and then line everything up, having to worry at minimum about elevation and […]

Computational imaging continues to grow in microscopy
The Waller Lab recently had a demo announcement of their awesome implementation of computational imaging. They have some examples on their lytro page, which look really cool! This got me thinking about the last 10 years or so, and how the combination of image capture with control over input and output image fields, has grown into a […]

Optical Design comes to the iPad!
Over the past 5 years, almost every project I’ve worked on has required some level of optic design. In many cases, simple designs suffice. For example, projecting an LED can be accomplished at a basic level with an aspheric condenser. But when designs require flat fields, especially corrective elements, or apochromatic performance, it’s time to leverage commercial […]

iPhone 6s Zoom & Resolution
Ever notice that no matter what zoom setting you use on an iPhone, the resolution of the captured image is the same? This defies convention, as normally, as a sensor is cropped digitally, the resolution of the resulting image should decrease. With Apple iDevices, this isn’t the case. The native resolution is always the same, […]

Cutting Filters using a CNC
SO I had a project where I needed a specific size of beamsplitter and I needed it quickly. Unfortunately, the type I needed wasn’t available from the usual sources, at least, not without a few days of lead time. What to do? It turns out, crazier people than me have been using CNC machines to […]
