Product Family Description

  • Ray Deviation of 90°
  • Left Handed Image
  • ±40 Arcseconds Angle Tolerance
  • Additional Right Angle Prism 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. TECHSPEC® High Tolerance UV Fused Silica Right Angle Prisms feature low arcsecond angle tolerance and and are made from precision UV fused silica for use in a variety of UV, Visible and NIR applications
