Hi, is there any clever way to implement a 4-way beamsplitter ? My current go-to is using three 'regular' (two-way) beam splitters .
Indeed there are. A Google search of "four way beam splitter" yielded:jeremy_rutman said:Hi, is there any clever way to implement a 4-way beamsplitter ? My current go-to is using three 'regular' (two-way) beam splitters .
behind paywall and not relevant- this is a two-input two-output deviceHyperfine said:Indeed there are. A Google search of "four way beam splitter" yielded:
Four-port integrated polarizing beam splitter
This is a chromatic filter splitting into e.g. R,G,B which is not what I'm after, I need 4 full-color images.Hyperfine said:
This is a theory paper , which posits use of arbitrary inhomogneous SLM's for its simulations - not something i nor anyone else is likely to be able to produce or buy. Furthermore the splitter here seems to be more or less analogous to use of three splitters .Hyperfine said:Designing the Phase and Amplitude of a Scalar Optical Fields in Three Dimensions
Those are just the first three hits that might be relevant to you.

it should be rather clear that use of that method is not, in fact, what I'm looking for.My current go-to is using three 'regular' (two-way) beam splitters .
A four-way beamsplitter is a type of optical device that uses a combination of mirrors and prisms to divide a single beam of light into four separate beams. The beamsplitter is designed to reflect a specific percentage of the incoming light while allowing the remaining light to pass through. This results in four beams of equal intensity being emitted from the beamsplitter.
Four-way beamsplitters are commonly used in optical systems for a variety of applications. They are often used in laser technology, microscopy, and spectroscopy. They are also used in telecommunications to split and combine signals in fiber optic networks.
The implementation of a four-way beamsplitter in an optical setup involves carefully aligning the beamsplitter with the incoming and outgoing beams of light. The beamsplitter is usually placed at a 45-degree angle to the incoming beam and the outgoing beams are directed towards the desired locations using mirrors or prisms.
One of the main advantages of using a four-way beamsplitter is that it allows for the splitting of a single beam of light into four separate beams without significant loss of intensity. This makes it a useful tool in various optical applications where multiple beams are needed. Additionally, four-way beamsplitters are relatively compact and can be easily integrated into optical systems.
While four-way beamsplitters have many useful applications, they do have some limitations. One limitation is that they can only split a single beam of light into four beams, so they are not suitable for applications where more beams are needed. Additionally, the intensity of the outgoing beams may not be exactly equal due to imperfections in the beamsplitter, which can affect the accuracy of certain experiments or measurements.
