UV Fused Silica Right Angle Prisms
• Ray Deviation of 90°
• Left Handed Image
• ±15 Arcsec, ±40 Arcsec, and ±5 Arcmin Options Available
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.

• Ray Deviation of 90°
• Left Handed Image
• High Refractive Index Material
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-SF11
Right Angle Prisms are made from high index N-SF11.
This high refractive index increases the optical path
length thus reducing physical working distance requirements.
TECHSPEC® N-SF11 Right Angle Prisms
are available uncoated or with an aluminized hypotenuse
and anti-reflection coated faces.
