Scanning Electron Microscope Vinyl Record

Secondary electrons are emitted from the surface of the specimen and recorded.
Scanning electron microscope vinyl record. A scanning electron microscope sem is a type of electron microscope that produces images of a sample by scanning the surface with a focused beam of electrons the electrons interact with atoms in the sample producing various signals that contain information about the surface topography and composition of the sample. Tactile and textured vinyl is all about psychical character. This first vinyl record image was captured at 100x magnification using reflected light through the objective lens. 6 3 1 scanning electron microscopy.
I also show electron micrographs of other. An electron probe is scanning over the surface of the material and these electrons interact with the material. A stunning and scary close up of vinyl record grooves. Chris supranowitz s opt 307 final project.
A 6 3 megapixel microscope digital camera was used to capture the images. May 23 2019 a scanning electron micrograph of a vinyl record. I was going to buy one to do this but when i found out they cost about 250 000 i decided we d use the lab s. Electron microscope and the path of the needle in a vinyl lp.
Electron microscope and the path of the needle in a vinyl lp. The electron beam is scanned in a raster scan pattern and the position of. So we switched to the scanning electron microscope. Scanning electron microscope sem is used to study the topography of materials and has a resolution of 2 nm.
I describe how i made a stop motion animation of a phonograph needle in an lp groove using an electron microscope. Although less delighted and actually quite horrified to see how much dirt and dust was lurking in between. The electron source and electromagnetic lenses that generate and focus the beam are similar to those described for the. Anyway here on the left you can see a dirty record compared with a clean one right above.
