  • The extinction ratio (ER) is the ratio of maximum to minimum transmission of a sufficiently linearly polarized input. When the transmission axis and input polarization are parallel, the transmission is at its maximum; rotate the polarizer by 90° for minimum transmission. These polarizers maintain an extinction ratio of at least 1000:1 over the full operating bandwidth.

Variable Optical Attenuator Application

A continuously variable attenuator can be assembled using the FiberBench components listed in the table to the right. Since a variety of AR coatings and connectors are available, we recommend selecting individual components suited to your application.

The FiberPort collimates the beam from a SM or PM fiber, and the collimated beam then goes through a calcite beam displacer (walk-off polarizer) where it is split into its respective horizontal (P) and vertical (S) components. The orientation of the wave plate controls how much energy is in the beam. It can be rotated to give the desired attenuation - zero, partial, or full. The signal then enters a reversed beam displacer where it will be recombined or further separated. The only energy that will couple back into the output fiber is the signal on the central axis. The central beam will then be focused into the output fiber by the output FiberPort.

Zero Attenuation
Click to Enlarge

The half-wave plate is rotated so that there is only one output beam; this also means that the input and output polarizations are the same.
Partial Attenuation
Click to Enlarge

The half-wave plate is rotated so that there are three output beams. Its orientation will control how much energy is in each beam. The only energy that will couple into the fiber is the energy in the central beam. The attenuation range is 1 to 40 dB with any value in-between.
Full Attenuation
Click to Enlarge

The half-wave plate is rotated so that there are two output beams, which will be displaced to the left and to the right of the center. In this position, there will be minimal coupling efficiency, resulting in a maximum attenuation of 40 dB.

Polarization Beamsplitter

Polarization Splitter

A polarization splitter can be assembled using the components listed in the table below. Since a variety of AR coatings, connectors, and configurations are available, we recommend selecting individual components suited to your application.

The offset (pickoff) mirror is positioned such that it will intersect the displaced beam from the preceding calcite beam displacer (walk-off polarizer) and reflect it by 90°. This combination simplifies the alignment of complex systems by decoupling the reflected beam from the transmitted beam, thus allowing for the independent adjustment of the reflected beam path. Alignment is critical when aligning systems with a walk-off/pickoff combination as clipping can occur if the beam is too large or not centered.

Reading a Vernier Scale on a Linear Main Scale

Vernier scales are typically used to add precision to standard, evenly divided scales (such as the scales on Thorlabs' rotation, goniometric, or translation mounts). A vernier scale has found common use in many precision measurement instruments, the most common being calipers and micrometers. The vernier scale uses two scales side-by-side: the main scale and the vernier scale. The direct vernier scale has a slightly smaller spacing between its tick marks owing to the vernier scale having N ticks for every N - 1 ticks on the main scale. Hence, the lines on the main scale will not line up with all the lines on the vernier scale. Only one line from the vernier scale will match well with one line of the main scale, and that is the trick to reading a vernier scale.

Figures 1 through 3 show a linear vernier scale system for three different situations. In each case, the scale on the left is the main scale, while the small scale on the right is the vernier scale. When reading a vernier scale, the main scale is used for the gross number, and the vernier scale gives the precision value. In this manner, a standard ruler or micrometer can become a precision instrument.

The 0 on the vernier scale is the "pointer" (marked by a red arrow in Figures 1 - 5) and will indicate the main scale reading. In Figure 1 we see the pointer is lined up directly with the 75.6 line. Notice that the only other vernier scale tick mark that lines up well with the main scale is 10. Since the pointer lines up with the main scale’s 75.6, the reading from Figure 1 is 75.60 (in whatever units the instrument measures).

That is essentially all there is to reading a vernier scale. It's a very straightforward way of increasing the precision of a measurement instrument. To expound, let’s look at Figure 2. Here we see that the pointer is no longer aligned with a line on the main scale, but instead it is slightly above 75.6 and below 75.7; thus, the gross measurement is 75.6. The first vernier line that coincides with a main scale line is the 5, shown with a blue arrow. The vernier scale gives the final digit of precision; since the 5 is aligned to the main scale, the precision measurement for Figure 2 is 75.65.

Since this vernier scale is 10% smaller than the main scale, moving the vernier scale by 1/10 of the main scale will align the next vernier marking. This asks the obvious question: what if the measurement is within the 1/10 precision of the vernier scale? Figure 3 shows just this. Again, the pointer line is in between 75.6 and 75.7, yielding the gross measurement of 75.6. If we look closely, we see that the vernier scale 7 (marked with a blue arrow) is very closely aligned to the main scale, giving a precision measurement of 75.67. However, the vernier scale 7 is very slightly above the main scale mark, and we can see that the vernier scale 8 (directly above 7) is slightly below its corresponding main scale mark. Hence, the scale on Figure 3 could be read as 75.673 ± 0.002. A reading error of about 0.002 would be appropriate for
this instrument.

Figure 1: An example of how to read a vernier scale. The red arrow indicates what is known as the pointer. Since the tick mark labeled 10 on the vernier scale aligns with one of the tick marks on the main scale, this vernier scale is reading 75.60 (in whatever units the instrument measures).

Reading a Vernier Scale on a Rotating Main Scale

The vernier scale may also be used on rotating scales where the main scale and vernier scale do not share units. Figures 4 and 5 show a vernier scale system for two different situations where the main scale is given in degrees and the vernier scale has ticks every 5 arcmin (60 arcmin = 1°). In each case, the scale on the top is the main scale, while the small scale on the bottom is the vernier scale.

In Figure 4 we see the pointer is lined up directly with the 341° line. Notice that the only other vernier scale tick marks that line up well with the main scale are ±60 arcmin. Since the pointer lines up with the main scale at 341°, the reading from Figure 4 is 341.00°.

There are two ways to determine the reading if the zero on the vernier scale line is between two lines of the main scale. For the first method, take the line on the left side of the pointer on the vernier scale and subtract that value (in arcmin) from the value on the main scale that is to the right on the main scale. As an example, in Figure 5 the vernier pointer is between 342° and 343°; using the left blue arrow of the vernier scale results in 343° - 15 arcmin = 342.75°. The second method is to take the reading from the blue arrow on the right side of the vernier pointer and add that value to the lower value from the main scale; reading the right blue arrow in Figure 5 results in 342° + 45 arcmin = 342.75°.

As we've seen here, vernier scales add precision to a standard scale measurement. While it takes a bit of getting used to, with a little practice, reading these scales is fairly straightforward. Vernier scales, whether they are direct or retrograde*, are read in the same fashion.

*A retrograde vernier scale has a larger spacing between its tick marks with N ticks for every N + 1 ticks on the main scale.

Response from Javier at Thorlabs to Benjamin: Thank you for contacting us. The fiber bench components are attached to the bench through a slip fit of the dowel pins into the mounting holes. The diameter of the dowel pins is 0.125" and the mounting hole diameter is 0.126" (+0.001"/-0.000"), which provides a tight fit between these mating parts. As a result, our fiber tables provide a stable support for polarizer modules and a variety of other optical components, and is also suitable for interferometry applications.

How are items fastened/secured to the fiber table? Do they just slot in? Does that provide sufficient stability for interferometry applications? Thanks, Benjamin

Thorlabs' FiberBench Rotating Linear Polarizer Modules utilize a thin layer of sodium-silicate polarizer mounted in FBR Rotation Mounts. These modules absorb light that is not aligned to the transmission axis of the polarizer and are designed for the 500 - 720 nm, 650 - 2000 nm, or 1.5 - 5.0 µm wavelength range. These polarizers provide an excellent extinction ratio of >10 000:1 over most of their specified wavelength range (see Specs tab for details). The transmission axis is marked by the engraved line on the front of the polarizer cells.

The mount for these polarizers features a rotating cell with a knurled edge and a 360° laser-engraved scale marked at 2° increments. A convenient top-located setscrew (0.050" hex) secures the rotational position of the optic cell.

These modules are ideal for a variety of polarimetry applications. Rotating linear polarizers can be used to monitor the polarization of a beam whose polarization state may shift over time due to temperature or other factors; the rotating polarizer can then be adjusted to maintain maximum transmission. A rotating polarizer can measure the polarization extinction ratio of another polarizer element without having to realign components in between measurements. Also, a variable beamsplitter can be constructed using a polarizer module in conjunction with a Beam Displacer Module (sold below).

The FBR mount can be coupled with an FBA post-mountable adapter for use in other applications. The mount is SM05 threaded and the removable polarizer cell is held in the mount with an SM05 retaining ring for holding Ø1/2" optics (SM05RR). The polarizer cells in these modules are also compatible with other Ø1/2" optic mounts. When replacing a polarizer in the mount, be sure to align the engraving on the polarizer with the 0° engraving on the scale. Please note that the thin film in these polarizers is very delicate and should not be touched.

Linear Polarization Reference Module


Click for Details

Four Available Orientations (Fourth orientation not shown)

Applications

  • Polarization Extinction Ratio Measurements
  • Polarimetry
  • PM Fiber Alignment
  • See the Applications Tab
  • Precision Linear Polarization Reference
  • 0°, 45°, 90°, and 135° Orientations
  • Angle Tolerance <30 arcmin
  • Highly Repeatable Positioning by Magnetic Contact
  • Wavelength Range: 1510 - 1590 nm

The Linear Polarization Reference Module consists of a Linear Polarizer held in a capture cage. The polarizer is set in the silver wheel on the front of the module, seen on the left, and can be rotated by adjusting the setscrew using a 0.035" hex key

To use the module, place the front of the module into the cage facing your source with the 1 located at the top. Rotate the front wheel so that it matches the polarization of your source, and tighten the setscrew using a 0.035" hex key, located on the face to the left of the 2. This corresponds to a 0° rotation with respect to the input polarization. From here, the module can be easily positioned to the 2, 3, or 4 settings, which correspond to a 90°, 45°, and 135° clockwise shift of the input polarization, respectively. Position 4 is achieved by flipping the module; the wheel on this side of the housing does not rotate the polarizer but can be adjusted for use as a reference. 

Please note that this linear polarization reference module does not incorporate a quarter-wave plate. However, other wavelengths and units with an integrated quarter-wave plate (to function as a manual polarimeter) are available by request. Please contact Tech Support for details.
