T-PS913 - N-BK7 Right-Angle Prism, Uncoated, L = 60 mm
T-PS913 - N-BK7 Right-Angle Prism, Uncoated, L = 60 mm
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.
