What is prismatic periscope?

Answer 1

A prismatic periscope is an optical device that uses prisms to reflect light and enable users to see objects that are not in their direct line of sight. Unlike traditional periscopes, which typically use mirrors, prismatic periscopes utilize total internal reflection in prisms to achieve a more compact design and improved image quality. They are commonly used in submarines, for surveying, and in various optical instruments. This design allows for a more efficient transfer of light and can provide a clearer image.
