Mar 10, 2016 — The diaphragm, a dome-shaped muscle at the base of the lungs, plays an important role in breathing — though you may not be aware of it.

The grooved side should face the sun if you want the maximum effect. As the following diagram shows, if the flat side is facing the sun then not all the light meets at the focal point. This is something I actually verified experimentally. With my fresnel lens solar cooker, it took 2.4 times as long to bring 150ml of water from 40C to 60C when the flat side was facing the sun compared to when the grooved side was.

The proper substrate preparation is critical to any finishing method. Our experience with a large variety of fabrications, extrusions, machined, stamped, and cast parts has taught us a great deal about processing lubricants and methods for removal to assure a clean surface.

Making a fresnel lens that doesn't suffer from spherical aberration is simply a matter of making the grooves less steep by appropriate amounts. This is easy to do since it means just cutting the grooves differently than they otherwise would have been. The resulting lens is referred to as an aspherical lens.

Our focus is on in process quality control, and from the moment your parts hit our dock. We'll not only monitor the quality of our process, we can work with your guidelines to identify and segregate non conforming parts.

Since our founding in 1976, Advanced Coating technology has been perfecting our use of powder coating technology. In our more than 40 years of experience, we have become experts at pretreating and coating cast, extruded, forged, stamped and welded components from a diverse range of industries. Our facility is outfitted with electrostatic spray and fluid bed capabilities so we can thoroughly coat whatever materials your business requires.

Advanced Coating Technology has been at the forefront of powder coating technology in Pennsylvania for more than 40 years. Our coating processes combine our efficient automation and the knowledge of our experienced operators who are constantly upholding the highest standards of quality. Each of our experienced technicians can apply your own powder coating solutions or recommend the coating service that works best for your project.

The following is a video I made showing much of the above, including the experiments I performed to verify some of it. Enjoy!

It turned out that the fresnel lens which I got from a rear projection TV and used for my solar cooker produces a short line at the focal length about 2 to 3 inches long and about a half inch thick at its thickest. However, my magnifying glass fresnel lens produces a sharp point, or spot, at its focal point.
