DIY Phone Microscope: 'Jugaad' to see tiny objects

All thanks to CUBE Chatshaala sessions, i came up with this great idea of making DIY Phone Microscope. During this Lockdown period, we (CUBist) have made a lab at Home named ( CUBE HOME LAB) and trying to Explore new ways of Learning.

Similarly i have tried to make a Phone Microscope that would allow me to explore tiny objects.
I would like to give some Examples related to our CUBE HOME LAB Work.
To see Two Breaks in Coastal vein, an incomplete sub-coastal vein and an Anal cell which are present in the wing of a Fruit Fly ( Characteristics features of Drosophilidae family)
To see tiny living creatures living in a drop of puddle water using Phone Microscope.

Requirements: The things i have used to make Phone Microscope were available in my house.

  1. A small white light torch
  2. A piece of plane paper
  3. A transparent plastic sheet ( i have used transparent file cover)
  4. Laser Pointer ( which is also available in the market in 20 to 30rs.)
  5. Cello Tape.
  6. Mobile Phone.

    Cut a piece of paper place it on the white light torch.

    Cut a small stripe of plastic sheet to make a Microscope slide and place that on the top of the white paper.

    Take out Laser Lens from the Laser pointer.

Put laser lens after the Mobile Phone camera to capture amazing pictures of tiny objects.

Nice to see a meeting of Optics and biology.

Physicists and Makers are becoming extremely interested in biology. Eg photosynthesis and the plethora of molecules used by plants to optimise photovoltaic effect such that minimal damage is caused by UV while optimal efficiency is maintained. A trick that can be applied to solar cells.10.1126@science.aba6630.pdf (823.8 KB) 10.1126@science.abc8063.pdf (239.1 KB)

help !!! 4
This is a ray diagram of a compound microscope, and all of us at Cube Chatshaala! are trying to understand how a microscope processes an image of an object. Could anyone help me explain how the image is formed in the mobile phone camera?? Probably ray diagram of a mobile phone camera.
Thank you!!!

Do you want to figure out how the whole setup of yours lens plus mobile camera functions as a microscope or how the mobile camera works?

First, how the mobile camera works and than i can correlate what happen when a lenser lens put after the mobile camera???

A simple mobile camera has a lens followed by a digital sensor. The latter converts light image into and electronic image that we see on the screen.

This is wonderful!

@saswathy679 has been working on fruit flies. To identify the fruitflies she needed to take a close look at their wings. She tried doing it with her mobile phone camera and torchlight. She has been reasonably successful, but to get better clarity, we started exploring more options.

@Farhan and @G_N suggested last week to not use digital zoom on her phone, to take a close enough picture directly and to zoom it later for better results.

@saswathy679, we are waiting for the results. You can start by posting the before and after pictures here, and we will continue the discussion.

Also, I think this can be a wonderful exploration for other investigations at home labs as well. For example, @saida786110 wanted to check the rotifers using a mobile camera. There was a similar exploration here tinkering a lens from the DVD by @singh (See here).
