Prism Binocular
Does anybody know how to make a binocular/periscope?I don’t want a regular plain periscope.10 pts to best answ
I have to create an optical device that would allow you to look at an object about 1 m above u and from about 10 cm of distance away or any distance away. I have to use mirrors, lnses, and prisms. I don’t want to make a regular periscope because that’s uncreative. We’re being marked on origanilty as well. I sorta wanna make a periscope/ binoculars. Something that works lie a periscope but you put it up to your eyes and you can get different magnifications. Please help! Any suggestions guys? I would be so grateful if you have a website.
i get the wheel part, but not exactly the shaft part. what do u mean?
For the different magnifications you could install a wheel type device. Only the upper portion of the wheel is exposes so you can turn the wheel to various positions simply by turning the wheel along the exposed portion.
Inside the wheel actually has several lenses attached to it, as the wheel turns the next lens aligns itself so that the image is being magnified with the lens in alignment. The wheel should have definite stops that can be felt as one turns the wheel. The stops must be at the point of alignment for the lens.
Therefore, by looking through the device, one can turn the wheel on top to rotate to the next lens and view an object at different magnifications.
The wheel could be installed on to a shaft, like a flywheel is on the motor of a car. The shaft is supported by brackets mounted to the housing, and the shaft hold the lenses in a plastic like wheel device itself. As the wheel turns the shaft turns to align the lens, as described above.The thing to do is to set it up so the wheel you turn only turns the shaft, this way a smaller wheel can be used to turn this shaft. It could be a gear to gear relationship between the wheel and the shaft.
