Is it all spaghetti?

A fork is solemnly stretched into the air, wrapped around it: spaghetti like a halo. This is the official logo of World Pasta Day, which takes place on October 25.

“At the World Pasta Congress held in Rome in 1995, pasta makers from around the world enthusiastically agreed that pasta—a healthy, delicious, popular, sustainable and convenient food—deserved annual worldwide recognition,” says the World Pasta Day website.

At SCHOTT Lighting and Imaging, we enjoy eating noodles but, unfortunately, cannot make a living from it. Instead, we manufacture optical glass fibers. To celebrate the day we wanted to approach our product a little differently than usual and ask ourselves: How do our light guides compare to different types of pasta?

For those who associate glass with windowpanes or drinking glasses, the comparison may appear misleading, but, in fact, glass fibers are about as pliable as cooked spaghetti. This malleability is useful when the light needs to be directed around corners or into a narrow space. In medical technology, for example, glass fibers in endoscopes guide light into the interior of the body.

There are also rigid light guides in which glass fibers are fused into a specific shape and can withstand extreme conditions. Believe it or not, you may have come across a rigid light guide at your dentist. The dentist uses these light delivery components to guide the blue light from the light source to your tooth to harden your filling.

UNBOILED FUSILI

RIGID LIGHT GUIDE

What do you think: Should we plan a trip to Rome to enthusiastically agree that there should be a World Fiber Optics Day?
