The Optics Contest is open to any project that focuses on the use of lenses, prisms, mirrors, filters, or other tools for shaping light. While this contest might seem technical, there are many common objects that could be elements in your project to make it eligible: cameras, binoculars, projectors, telescopes, reading glasses, and so on. Show us your best optics-related project for your chance to win a host of cool prizes including an iPhone X!

The Optics Contest is closed.

How It Works

Write an Instructable

Create a new Instructable that fits the guidelines outlined in the contest description above. To be eligible, Instructables must be published between Oct 1, 2018 and Nov 26, 2018 (11:59pm PT).


Upon publishing your Instructable you'll see checkboxes for open contests. Select Optics Contest. If you have entries currently eligible for entry, it will also show up by clicking "Enter this Contest" on the right side of this page.


Entries are accepted by Instructables staff within one business day Monday - Friday. What matters is the submission time, not acceptance time.


A panel of judges made up of Instructables staff and respected members of the community rate the finalists. The averages of the ratings determine the winners.


When the winners are decided they will be notified and announced here on the contest page.
