Prism comparison of Porro and roof prisms

Difference and comparison between porro prisms and roof prisms

The design of the binoculars is always determined by the type of prism used.

Long-distance guests with the Porro prism construction can be recognised by its relatively low height and wide design. Advantage: The greater distance between the two lenses promotes spatial vision. A graphic illustration and further details on the Construction of porro prisms get it here!

Roof prism for binoculars

Long-distance glasses with Roof prismsThe main difference between the roof edge and the Porro system is the roof edge, where one of the reflective surfaces resembles a house roof (see picture below). " More info have a slightly slimmer and longer design. The roof prisms are a more modern design with several precisely ground prisms. PrismsLenses have the property of imaging objects upside down and laterally inverted - therefore the image must be rotated again. " More info - This makes the production of roof prism glasses more complex. Advantage: Glasses of this design are particularly slim and easy to handle.
