• Manipulate Image and Line of Sight
• Uncoated and BBAR Coated Options
• Combine Schmidt and Half Penta to Create Pechan Prisms
TECHSPEC® Visual Instrumentation Prisms deviate beams by either 90° (Amici) or 45° (Schmidt and Half-
Penta) without inverting or reverting images. This makes them useful for optical imaging instruments such
as binocular microscopes for which it is desired to redirect an image without inverting it. Each prism has an
N-BK7 substrate and is held to stringent angular and dimensional tolerances to ensure optimum resolution
and facilitate system alignment. Amici and Schmidt prisms are available with a metal coating on the roof faces
which reduces polarization anomalies, improves image brightness and resolution, and increases ray acceptance
angle. Schmidt and Half-Penta prisms can be combined to create Pechan prisms which rotate an image 180°
without deflecting the beam.

• Provides Inline Image Rotation of 180°
• Compact Design for OEM Integration
• Air Spaced for Optimal Performance
TECHSPEC® Pechan Prisms leverage Edmund Optics'
manufacturing expertise to deliver a precision inline
instrumentation prism to rotate an image by 180 degrees.
This image rotation is employed in many direct
view applications and replaces a relay prism or
lens system for a more compact optical train. Overall
clarity of the system is ensured by adding both an
anti-reflective and metallic coating to each prism. The
TECHSPEC® Pechan Prisms feature 5 arcsecond roof
angle tolerances to maintain image resolution.
