Thorlabs' Wire Grid Polarizing Beamsplitter Cubes consist of an array of parallel metallic wires sandwiched between two N-BK7 prisms. Wire grid polarizers transmit radiation with an electric field vector perpendicular to the wire and reflect radiation with the electric field vector parallel to the wire. These cubes separate the s- and p-polarized components by reflecting the s-polarized component at the wire grid, while allowing the p-polarized component to pass. Due to surface reflections, the reflected beam contains both polarizations.

This type of beamsplitter cube has a larger Angle of Incidence (AOI) than traditional broadband polarizing beamsplitter cubes. For the highest polarization extinction ratio, use the transmitted beam, which offers an extinction ratio of T_p:T_s > 1 000:1 for an AOI from 0° to 5°. For higher AOI (5° to 25°), these cubes can maintain an extinction ratio of T_p:T_s > 100:1.

The wire grid is sandwiched between the hypotenuses of the two prisms that make up the cube. Then, optical cement is used to bind the two prism halves together (refer to the diagram above). The engraved dot on the top of the cube indicates the prism with the wire grid polarizer. Light can be input into any of the polished faces to separate the s- and p-polarizations. One possible orientation is engraved on the top of the cube. Please refer to the BS Cube Mounting tab above for information on mounting options and compatibility.

These beamsplitter cubes are AR coated for 400 - 700 nm (R_avg < 0.5% @ 0° AOI). Custom beamsplitter cubes can be ordered by contacting Tech Support. For high power applications, we also offer high-power polarizing beamsplitting cubes that have damage thresholds greater than 10 J/cm². Mounted wire grid beamsplitting cubes are available. We also offer polarizing beamsplitter cubes at laser line wavelengths, which have a high extinction ratio of >3 000:1 (T_p:T_s).

Thorlabs' portfolio contains many different kinds of beamsplitters, which can split beams by intensity or by polarization. We offer plate and cube beamsplitters, though other form factors exist, including pellicle and birefringent crystal. Many of our beamsplitters come in premounted or unmounted variants. Below is a complete listing of our beamsplitter offerings.

Polarizer Selection Guide

Thorlabs offers a diverse range of polarizers, including wire grid, film, calcite, alpha-BBO, rutile, and beamsplitting polarizers. Collectively, our line of wire grid polarizers offers coverage from the visible range to the beginning of the Far-IR range. Our nanoparticle linear film polarizers provide extinction ratios as high as 100 000:1. Alternatively, our other film polarizers offer an affordable solution for polarizing light from the visible to the Near-IR. Next, our beamsplitting polarizers allow for use of the reflected beam, as well as the more completely polarized transmitted beam. Finally, our alpha-BBO (UV), calcite (visible to Near-IR), rutile (Near-IR to Mid-IR), and yttrium orthovanadate (YVO₄) (Near-IR to Mid-IR) polarizers each offer an exceptional extinction ratio of 100 000:1 within their respective wavelength ranges.

• Click on the graph icons in this column to view a transmission curve for the corresponding polarizer. Each curve represents one substrate sample or coating run and is not guaranteed.
• Mounted in a protective box, unthreaded ring, or cylinder.
• Available unmounted or in an SM05-threaded (0.535"-40) mount that indicates the polarization axis.
• Available unmounted or in an SM1-threaded (1.035"-40) mount that indicates the polarization axis.
• Available unmounted or mounted in cubes for cage system compatibility.
• Calcite's transmittance of light near 350 nm is typically around 75% (see Transmission column).
• Available unmounted or in an unthreaded Ø1/2" housing.
• The transmission curves for calcite are valid for linearly polarized light with a polarization axis aligned with the mark on the polarizer's housing.
• The 1064 nm V coating corresponds to a -C26 suffix in the item number.
• Available unmounted or mounted in a protective box or unthreaded cylinder that indicates the polarization axis.
