Right Angle Prism Mirrors

Right Angle Prism Mirror, Total Internal Reflection
  • Material: UV fused silica or BK7
  • Clear Aperture: larger than 85%
  • Surface Quality (Scratch-Dig): 10-5 for UV fused silica, 20-10 for BK7
  • Surface Flatness: λ/10 @633nm for UV fused silica & BK7
  • Angular Deviation: ±3 arc min
  • Bevel: <0.5mm @45˚ typical
  • Reflection: R≤0.25 for V-coat, R<0.5% for BBAR

  The total internal reflection (TIR) in the right angle prisms with specific anti-reflection (AR) coatings on the two leg sides make themselves the perfect alternatives of 45 degree mirrors. The TIR is independent of wavelength so the RAP mirrors can be used as high energy reflectors for broadband applications where metal mirrors are too absorbing and dielectric mirrors do not reflect a wide enough bandwidth.
  The other advantage of the RAP mirror is that the input and the output lights meet the surfaces always normally so they don't make any difference per polarization. They are perfectly non-polarizing 45° bending mirrors that any dielectric coatings can't do.
