      That’s a great question guys!
      A standard microSD card has a length and width of 15 mm × 11 mm (from google). The lasers I work with are about 1mm x 0.005mm, so after some quick maths and leaving some space between them….about 20,000 lasers!

      That’s the first time I’ve ever gone through those numbers, it really puts it into perspective how small lasers can be!
