Product Drawing

• 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

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
