AssemblyThese kits include all the hardware needed for assembly and adjustment. To assemble, insert the dowel pins of the half-wave plate and beamsplitter module into the desired slots on the FiberBench; lock their positions using the 2-56 set screws and 0.9 mm hex key. The beamsplitter cube can be aligned using four 0.050" hex adjustment screws, which can then be locked in place using their locking collars and the included SPW403 spanner wrench. The X, Y, and Zθ adjusters for each FiberPort also accept the 0.050" hex key. The sensitivity of the X and Y adjusters can be varied using the two holes located on the faceplate of the FiberPorts and the 0.028" hex key. The orientation of each FiberPort may be locked using the included 0-80 locking screws and the 0.050" hex key. Care must be taken when locking the FiberPort to avoid misalignment or damage. In most cases locking is not required. Please reference the FiberPort Manual for instructions. The rotation of the half-wave plate may be locked using the screw located at the top of the wave plate and the 0.050" hex key.

Beam splitter

While digital photography is a lot easier than photographing with film, the process is still the same. And as one of the most important inventions of all time, we’re excited to have you in this class to learn even more.

These beamsplitters have extinction ratios of >1000:1 (TP:TS). The average p-component transmission is >90% while the average s-component reflectance is >99.5% for each beamsplitter. Please see the Graphs tab for more information. The split ratio is continuously variable from 0 to 30 dB and is dependent on the polarization extinction ratio from the input PM fiber and the spectral line width when Δλ ≤ 3 nm.

That light goes into your camera through the lens, which has an aperture inside, an opening that lets in the light. The light passes through the camera’s shutter which in many cameras opens when you press the ‘shutter release’ button to let light in… and the light hits your camera’s sensor, where it is digitally captured and saved as an image.

These Variable Polarization Beamsplitter Kits are based on Thorlabs' FT-51X60 Multi-Axis FiberBench. A PM fiber can be attached to the input FiberPort, which collimates the output. The FiberPorts included with these kits have wide key slots. The polarization of this beam is then rotated with a half-wave plate. By changing the orientation of the wave plate, the ratio of the vertical to horizontal State of Polarization (SOP) is changed, which then affects how much signal is transmitted and reflected through the polarizing beamsplitter cube.

At its core, photography is about capturing light. Your camera can see bright light, and if there’s an absence of light. It can see colors too!
