Papercraft is a wonderfully accessible thing, and so what better project to make than a paper iris diaphragm. Building on lessons learnt from last time, we go into more depth, and cover every single step in the design process. What Is An Iris Diaphragm? Let’s start with a quick recap and inform ourselves what an […]

Diffraction Spikes Produced by Iris Diaphragms
While we have all been blown away by the first set of images that arrived yesterday from it’s L2 parking orbit, up until recently we’d only seen NASA’s James Webb Space Telescope (JWST) incredible calibration images. One of which highlighted very obvious diffraction spikes – a phenomenon caused by the edges of objects placed in […]
