Tech Spec Amici Roof Prisms

Amci Prisms , also called "roof prisms" or right angle roof prisms,"do two things:invert the time image and bend the line of sight through a 90angle.They are excellent as prism diagonals in optical systems, because they erect the inverted image. Also ideal for use in spotting scopes, and any optical instrument where it is desirable to take an inverted image from an objective,turn it right side up, and bend it through a 90angle, to maintain the correct visual orientation. All Amici prisms have 6 arc second resolution. All dimensions are in mm.
