Lens turns any smartphone into a portable microscope

Summary:
The Micro Phone Lens can turn any smartphone or tablet
computer into a hand-held microscope. The soft, pliable lens sticks to a
device's camera without any adhesive or glue and makes it possible to see
things magnified dozens of times on the screen.

Imagine yourself examining species of coral in Fiji. Looking
at fungi and parasites in grass seeds. Following ants across the ground up
close, or examining the striations in a piece of roast beef on rye.
People
around the world are doing all this and more with a tiny, durable magnification
lens built by an enterprising University of Washington undergraduate student.
The Micro
Phone Lens, developed by UW mechanical engineering alumnus Thomas Larson ('13),
can turn any smartphone or tablet computer into a hand-held microscope. The
soft, pliable lens sticks to a device's camera without any adhesive or glue and
makes it possible to see things magnified dozens of times on the screen.
"A
microscope is a tool you can do thousands of different things with and by
making it cheaper, portable and able to take pictures, you open so many
different possibilities that weren't available before," Larson said.
Larson
completed his undergraduate degree in 2013 and formed his own company based in
Olympia, Wash. After the initial success this winter of his first model that
magnifies by 15 times, he is creating a new lens that will magnify up to 150 times.
(Standard laboratory microscopes usually magnify between 50 and 400 times.)
The lens is
about the size of a button and comes in its own carrying case. Users stick it
flat onto a smartphone camera lens, turn on an external light source such as a
lamp, then run the device in camera mode. Moving the device closer or farther
from the object brings it into focus.
Several
other products exist that can adapt a smartphone to be used as a microscope,
but they are significantly more expensive, and the attachments are heavy or
require permanent adhesives.
Larson
developed his smartphone lens while working in the lab of Nathan Sniadecki, a
UW associate professor of mechanical engineering. The lab needed a miniaturized
lens that could work with a cellphone as a microscope, and Larson took on the
project. The lens he developed is now as powerful as the research microscopes
used in the lab, Sniadecki said.
Larson
decided to commercialize his product and participated in the 2013 UW Business
Plan Competition, where his team placed in the top 16. Funding trickled in
through various awards and scholarships that helped with early prototypes and
advertising materials, but the project's potential was still iffy.
"Thomas
did something that was truly unique -- he dove right into the technology and
the entrepreneurship," Sniadecki said. "Most mechanical engineers
have jobs lined up after graduation, but Thomas chose to forego the 'safe' path
and plunged himself into risky water."
After
graduating last summer, Larson ran a Kickstarter campaign for the 15X
microscope lens, and more than 5,000 people signed up. For the new graduate who
was still looking for a job and living with his parents in Olympia, this was a
sure sign of success.
"It all
just happened," he said. "Working at the UW helped me figure out the
technical and business problems, but the Kickstarter proved this technology is
something people wanted."
Larson
shipped orders to people around the world who needed a microscope they could
use in the field or in classrooms where expensive microscopes are in short
supply. Now, he is creating the 150X lens, which will be available this summer.
He manufactures the lenses at his lab space in Olympia and is working with an
optical mold-making company to design more sophisticated optics for this new
model.
Larson said
he hopes the new design will be useful in disease diagnosis overseas, and in
the increasing number of classrooms where iPads are the norm but microscopes
still come at a premium. He is working with a global health physician to try to
test the microscope at a clinic in Kenya, and he's getting feedback from
teachers on what they need for their students.
"I'm
hoping this microscope can make a difference," Larson said. "If I can
just make it available, the right people and experts in the field can see its
usefulness and take it from there."
