1. Porro Prisms As a result of the Porro crystals, the light going through structures a “Z” shape before coming to the eye.
2. Roof Prisms When utilizing rooftop molded crystals, called Roof (or Dacha: which means rooftop in German) crystals, the light goes through in a straight line, which makes it conceivable to configuration minimal binoculars.
