Frequently Asked Questions

General FAQ

What is Foldscope?

Foldscope is the paper microscope with 140X magnification.

Why invent a paper microscope?

Microscopes are important tools for science, but they are often expensive to access and own. Foldscope’s design uses low-cost materials (like paper) to provide a research quality microscope for a fraction of the price so that everyone can explore the microscopic world.

What is Foldscope made of?

Foldscope is made of a lens, magnets, and paper. The lens is a glass ball that magnifies things. The magnets align and place the lens, and help devices attach to the Foldscope. The rest is of the Foldscope is a waterproof paper!

What can you see with a Foldscope?

Foldscope’s lens has a magnification of 140x. With that, you can see tiny things like bacteria, blood cells, and single-celled organisms like copepods, tardigrades, tetrahymena, diatoms, rotifers, nematodes and more. As well as larger things like a insects, fabrics, tissues! Foldscope can also allow the observation of non-biological samples, such as particulates detrimental to air quality, or the microscopic crystalline differences between real and fake medications. Despite a number of amazing applications already demonstrated, we know there is so much untapped potential. Make the journey your own!

See for yourself what Foldscope users are exploring on our Microcosmos community website.

Is Foldscope a real microscope?

Yes! Foldscope is a simple light microscope with standard magnification of 140x. Foldscope is a twist on a traditional technology, combining the basics of an simple light microscope with super low-cost materials.

Do I need a camera phone to use the Foldscope?

No. Our philosophy is to bring the microscopic world to everyone. For this reason, Foldscope is designed to be an independent instrument and does not require a phone to use.
Foldscope can be coupled to phones/iPads/ recording devices. No special app is required- your standard camera application will suffice! Learn how to collect photo and video data here Foldscope Tutorials.

What age should you be to use a Foldscope?

We recommend age 8 and above for use of the microscope. Some younger children are able to use it with adult supervision.

Community

What is the Foldscope community?

The Microcosmos is the collective term used for the Foldscope community & online platform. The best part of Foldscope is not in the tool itself, but the people that use it!

What is on the Microcosmos?

The Microcosmos website is where Foldscope users from around the world connect, share their observations, ideas, and problems! It is a place to collaborate, find inspiration, and learn from fellow explorers. With over half a million Foldscopes in the world, it is quite the far-reaching and fascinatingly diverse community.

Can I join the Microcosmos?

If you have a Foldscope, yes, you can create a Microcosmos account.

Visitmicrocosmos.foldscope.com and select the ‘register’ tab. Complete the form to create and account. The form requires the code from your unique ID Sticker, shown right. The sticker’s code is your ticket into the Microcosmos!

If you do not have a Foldscope, you cannot create a Microcosmos account.

However, you can still browse the website and see what users are up to!

What is the global reach of Foldscope?

As of 2020 we have distributed over one million Foldscope units to 135+ countries. As a globally focused organization, we hope to democratize access to science across resource-rich and resource-poor areas, and to uncover the amazing biodiversity of the entire world.

Product Questions

Why the difference in price between Deluxe Individual Kits and Classroom Kits?

Our mission is to bring bring affordable scientific tools to everyone (not just communities who have the resources - but everyone). For any of this to be possible, our business model balances our cost of operations with offering extremely low-cost (low-profit) products. 

We find this balance through a pricing structure that operates on a 2-tier system: high price point kits for individual Foldscopes (Deluxe Individual Kits), and low price point kits for bulk Foldscopes (Classroom Kits).  

We arrived at this pricing structure for many reasons, but primarily because the reality of fulfillment and shipping means we cannot ship a single Foldscope that costs roughly $1 in parts to produce at a $1 dollar price while being sustainable. Overall, we make a profit only from our high price point kits, this profit allows for us to exist and produce any microscopes at all, and this profit also subsidizes our low price point kits (which we do not profit off of), in which offer Foldscopes for as inexpensive as $1.75 each!

Learn more about the different kits below:

Deluxe Individual Kits provide a user with a Foldscope and everything they need to start exploring (cell separation tools, microfluidics tools, and dark field and phase contrast modules). Not only are these kits fantastic to help you get the most out of your Foldscope, but their proceeds directly subsidize our classroom kits. By purchasing a Deluxe Individual Kit, you directly support our mission!

Classroom Kits are designed for educators, humanitarian projects, and causes looking to cater to large groups of explorers. Thanks to the proceeds of Deluxe Individual Kits, we are able to bring the costs down to $1.75 per Foldscope.

I can't find my lens.

The lens piece is a small circular item, composed of a tiny glass bead held within a black plastic ring and a silver magnetic ring. Magnetic couplers are square shaped pieces, composed of black plastic with small holes along one side, a large hole in the center, and a silver magnetic ring.

Due to their magnetic attraction, lenses and couplers will be stuck together in a stack when you receive your kit. This is normal! Simply separate the pieces and you are ready to assemble. (Video here: Magnetic Couplers & Lenses). 

I think have a missing or broken component in my kit.

We do extensive quality testing, but in the rare event a piece is missing or damaged, we will send a replacement part! Please fill out this form, and send us a picture of your product at info@foldscope.com. This will ensure that we properly log your request. The form requires your shipping address information and the batch code for your Foldscope, so please have your shipping information and Foldscope shipment available as you complete the form.
