3853

      Convex Glass Lens with Edge - 40mm Diameter PRODUCT ID: 3853 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 gorgeous glass (not plastic/acrylic!) 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 glass 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.
