N-BK7 Right Angle Prisms
• Ray Deviation of 90°
• Left Handed Image
• Low Angle Tolerance
Right angle prisms are generally used to bend image
paths or redirect light at 90°. This produces a
left handed image and depending on the orientation
of the prism, the image may be inverted or reverted.
Right angle prisms can also be used in combination
for image/beam displacement. TECHSPEC® N-BK7
High Tolerance Right Angle Prisms feature low arcsecond
angle tolerance and are made from precision
N-BK7 for use in a variety of visible light applications.
