WebI built an optical projector to observe the Venus transit with a 10x50 monocular. I mounted the monocular inside a box, leaving a small window to observe the projection. The focusing capability of the monocular was necessary to get a good image. The Sun's image was large and bright and detailed, much better than a pinhole projector. WebOct 12, 2024 · Detailed Features of the Pinhole Projector Images Diffraction rings: These are caused by small dust particles or tiny defects on the vacuum window. They show up as diffraction rings because the pin hole projector produces a very collimated optical beam, much different than the F#1.23 beam we have in the Rubin Observatory.

WebPinhole Optics and Resolution Most optical devices rely on refraction or reflection to provide an image on a screen or film plane. A pinhole camera is a device which uses neither lenses nor mirrors to produce its image, but rather only a small circular aperture, or ‘pinhole’. This apparent lack of what one might consider an imaging optic does WebWe found that a 5 mm pinhole held 3-4 feet above the ground provided the strongest and clearest pinhole projection of a partial eclipse.
