Wollaston prism

These are very interesting beam splitters. You can think of them as selective mirrors (actually, some vendors sell them as dichroic mirrors and others as dichroic beams splitters). The idea is that these optical elements have a cut-off wavelength. So light above their threshold will be transmitted and wavelengths below them will be reflected. These beam splitters are widely used in scanning microscope designs and confocal microscopes.

The resulting time will generally be very long, so you will have to adjust for reciprocity failure; unfortunately, different films require different adjustments, so you will have to determine the proper formula from the tech sheets for the film you are using. A rule of thumb for most black-and-white films is as follows:

Depending of your application, you may benefit by using some custom made beam splitters. If you would like more information, please contact us.

Calculating exposures for your pinhole camera can be difficult. The Lensless Camera Mfg. Co., whose models we sell, has provided us with the following table of apertures and f-stops for their products. Please note that the format (4x5, 5x7, etc.) of the camera is irrelevant; only the working aperture and focal length determine the f-stop.

Normal light meters do not, of course, work with abnormal cameras, but a relatively simple calculation will permit you to meter for a larger f/stop and convert the time given to one suitable for your pinhole camera. If you:

Depending on the material and thin-films used to fabricate the beam splitter, you can have an optical element that works in a very specific region of the electromagnetic spectrum. As in many other optical components, these bands are usually: 280-400nm for UV, 400-700 nm for visible, 700-1100nm for NIR, and 1100-1600 for IR.

Polarizingbeamsplitter

These beam splitters divide the incoming light into two beams with different polarizations. You have to be careful when orienting these beam splitters to determine which polarization (S- or P-) will be transmitted and which one will be reflected. A very interesting way to create the polarizing effect is by placing an array of metallic wires between two BK-7 (or different glass) prisms. A further advantage of using this wired grid is that the Beam splitters will have a larger angle of incidence than traditional beam splitters based on thin-film elements.

Beamsplitter Hamiltonian

They can be shaped as a cube or a plate and their price can be just a couple of hundred dollars in low volume and a few dollars in production volume (although, as with many optical components the price is strongly tied to the size of the component).

Beam splitters are a fundamental element in optical systems. Beam splitters are, in essence, optical components used to divide a single light source (usually a laser) into two separate beams. The more common kind of beam splitters (the kind that you can find in most colleges or labs) is a beam splitter that can split the light source into two beams regardless of the light source’s wavelength or polarization.

Mach-Zehnder interferometer

However, it is possible to create more interesting beam splitters that can be used for very specific applications. Here are just a few different kinds of beam splitters:

The working principles of a diffractive beam splitter are similar to diffraction grating. In the case of DOE however, the diffraction grating grooves have a more complex shape (in the case of 1D array) or the DOE can have a complex binary or analog format surface with a 3D periodic structure. The diffractive beam splitter allows the creation of any type of spot arrays (1D, 2D, or irregular) while maintaining high efficiency and uniform distribution of energy in the spots.

A diffractive beam splitter is a diffractive optical element (DOE) used to split a single collimated laser beam into several beams with the same optical characteristics as the original beam. Beams are usually separated into 1D or 2D arrays and may be arranged regularly or irregularly. A diffractive beam splitter is used with monochromatic light (such as a laser beam) and is designed for a specific wavelength and angle of separation between output beams.

It is possible to design a beam splitter whose split beams don’t have equal amount of light intensity. For example, a 10:90 (RT) beam splitter will provide you with a reflected beam with 10% of the source intensity and 90% of the source intensity will be in the transmitted beam. Similarly, you can have any possible ratio, although the most common off-the-shelf ratios are: 10:90, 30:70, and 50:50.
