N-BK7 Penta Prisms

×
  • Ray Deviation of 90°
  • Right Handed Image
  • Optical Tool for Defining a Right Angle
  • Additional Penta Prism Options Available

TECHSPEC® N-BK7 Penta Prisms are five-sided prisms featuring a ray deviation of 90° and a right-handed image. The reflecting surfaces are aluminized. Slight movement of the prism does not affect the true right angle at which light rays are reflected, making a penta prism the ideal optical tool for defining a right angle in an optical system. TECHSPEC® N-BK7 Penta Prisms are made from precision N-BK7 for use in a variety of visible light applications. These prisms are offered with a VIS 0º or MgF2 coating, in a variety of sizes.
