Features

  • Sizes Ranging from 3 mm to 60 mm
  • Fabricated from N-BK7, UV Fused Silica, CaF2, or ZnSe
  • N-BK7 Prisms Available with an AR Coating on the Hypotenuse or Both Legs

Thorlabs' high-precision Right-Angle Prisms can be used to deviate a light path by 90° or 180°, depending on which surface is used as the input for the light source. These prisms are fabricated from N-BK7, UV fused silica, CaF2, or ZnSe, and they are offered in sizes ranging from 3 mm to 60 mm. Our N-BK7 right-angle prisms are available uncoated or with one of our three standard broadband antireflection coatings (-A: 350 - 700 nm, -B: 650 - 1050 nm, -C: 1050 - 1700 nm) on either the hypotenuse or both legs, thereby reducing surface losses.

Due to total internal reflection (TIR), Video 1.2 demonstrates how the right-angle prism can be used as a 90° reflector. When the input light is incident on one of the prism's legs, it undergoes TIR at the glass/air boundary of the hypotenuse and exits via the other prism leg. This 90° deviation of the input light makes the right-angle prism a suitable alternative to a mirror.

Video 1.3 shows how the right-angle prism can be used as a 180° retroreflector. When the input light is incident on the face of the hypotenuse, it undergoes TIR at the glass/air boundary at the prism legs. It undergoes TIR a second time at the next prism leg and exits the hypotenuse in a path parallel to that of the input beam. Like the retroreflector, the 180° deviation of the light path is independent of the angle at which the light enters the prism.

Please refer to the Prism Guide tab for assistance in selecting the appropriate prism for your application. For additional antireflection coating requests, please contact Tech Support.

Figure G1.1  Transmission curve for a 10 mm thick uncoated sample of UV fused silica when the incident light is normal to the surface. Please note that this is the measured transmission, including surface reflections.

Choose a UV Fused Silica Right-Angle Prism if your application would benefit from higher transmission in the UV or a lower coefficient of thermal expansion. UV-grade fused silica offers high transmission in the deep UV and exhibits virtually no laser-induced fluorescence (as measured at 193 nm), making it an ideal choice for applications from the UV to the near IR. For a given wavelength, UV fused silica also has a lower index of refraction than N-BK7. Please see the Graphs tab for a graph of index of refraction vs. wavelength for UV fused silica.

Choose an N-BK7 Right-Angle Prism if the additional benefits of fused silica are not required. N-BK7 provides excellent transmittance in the visible and near-infrared portions of the spectrum. Please see the Graphs tab for a graph of index of refraction vs. wavelength for N-BK7. Additionally, N-BK7 is a viable choice for UV applications down to 350 nm. For applications that demand maximum transmission, please see our AR-coated N-BK7 prisms below.

Our PS911K Knife-Edge prism offers the same features as our standard N-BK7 right-angle prisms but features an unbeveled, precision 90° edge between the two legs. This means that the clear aperture reaches across this surface, making this prism ideal for applications where a larger clear aperture is beneficial. It also offers enhanced surface flatness and quality; see the Specs tab for Details

Figure G4.1  Transmission data is for two 25 mm right-angle prisms contacted into a cube.

Zinc selenide is ideal for use in the 600 nm - 16 µm range. It features low absorption (including in the red visible wavelength range) and high resistance to thermal shock. ZnSe is ideal for use in CO2 laser systems operating at 10.6 µm, including those with HeNe alignment lasers. Please see the Graphs tab for a graph of index of refraction vs. wavelength for ZnSe.

When handling optics, one should always wear gloves. This is especially true when working with zinc selenide, as it is a hazardous material. For your safety, please follow all proper precautions, including wearing gloves when handling these prisms and thoroughly washing your hands afterward. Due to the low hardness of ZnSe, additional care should be taken to not damage these prisms. Click here to download a pdf of the MSDS for ZnSe.

Thorlabs will accept all ZnSe prisms back for proper disposal. Please contact Tech Support to make arrangements for this service.

Dangerous Goods
Please note that the PS701 and PS702 prisms are classified as dangerous goods in some countries. Depending on the delivery location, these items may need to be shipped separately from the rest of your order (and possibly with a different carrier) at an additional charge.
