3917

      Convex Plastic Lens with Edge - 40mm Diameter PRODUCT ID: 3917 The eyes have it! Add this little lens to make a big expression with our Spooky Eyes demo for microcontrollers or Raspberry Pi. These are plastic lenses, with brilliant clarity and a nice convexity (is that a word?) They've even got a lip-edge so you can mount them easily with a 38mm cutout. We've attached these to our Raspberry Pi Animated Eyes Bonnet Kit for a real nice upgrade! This product is just a single PLASTIC lens. Perfect for use with our Raspberry Pi Snake Eyes Bonnet guide or our Electronic Animated Eyes guide. Check out both of those for the full listing of what you'll need. Of course, these work great for other purposes when you need a convex lens. Interested in an even fancier upgrade? Check out the GLASS lens - it's heavier but less scratch-prone.
