Make 4 types of Telescopes | Journey of making binaculars without prism

Make Binaculars at home
we explored all types of binoculars. I tried combination of convex concave lenses

1.made kids binocular using convex and concave lens
2.made telescope using 2 convex lenses
3.professional binoculars using mirrror erector

Telescope produces inverted image so i used mirrors to make upright image.
I took 4 mirrors and arranged them properly to make mirror erector

Generally companies use roof prism or porro prisms to erect the image. prism is costly and not possible to make at home
So mirror erector is alternative way to DIY erector.

Learn about the principles of optics, how lenses form images, and the role of mirrors in creating a clear, upright view.
This in-depth explanation will help you understand lenses,non-prism binoculars,How lenses magnify image.Also understand how prism erects inverted image.

By watching this video 11th 12th neet / jee class students can understand optics/ telescope /Binoculars in most interesting way

I used 30cm convex lens vs two 5 cm convex lens so it produces nearly 12 times zoom
