Penta Prism is a five-side prism containing two reflecting surface at 45?/SPAN> to each other, and two refracting face perpendicular to the entering and emerging beam. The important propertie of Penta Prism are:

The image neither inverted nor reversed, just deviated 90?/SPAN>.

With the prism, a constant deviation angle applies to all rays transmitted by useful aperture, regardless of the angles between these ray and the optical axis (or entrance and exit face normal).
