450x Magnification with HIGH-MAG LENS?

Hello Foldscopers,

I am writing to express my doubt on the foldscope magnification.

I have bought a foldscope (it has blue color) bought on amazon

https://www.amazon.in/Vitals-Foldscope-Classroom-Paper-Microscope/dp/B07R4MGBPC/ref=sr_1_3?dchild=1&keywords=foldscope&qid=1593341447&sr=8-3 )

And it says 140x magnification.

But when i read a article on foldscope it said foldscope has 450x Magnification. Also what is the difference between the white colored foldscope and the blue colored foldscope? I would like to buy the 450x lens can you please share a link from where i can purchase the lens?

Thanks And Regards,

Aditya Ubarhande (from India)

    Dear Aditya,

    Commercially available Foldscope only comes with a single 140x lens. See http://www.foldscope.com for the official product website.

    The confusion might come from the fact that the academic paper in which we describe foldscope (plos one ) we demonstrate multiple high magnifications and the beta program; we shipped an older version of foldscope with 450x mag as well.

    But all current version of the foldscope are 140x!

    Hello Manu Prakash Sir,
    So is there any way by which i can zoom more than 140x (not by the camera zoom)
    like making a lens or optimising the one that is present??
    I would really appreciate a quick response
