Beamsplitter The beamsplitter is one of the most expensive and sensitive components of an interferometer, and must be chosen
Internal component of the box-type beam splitter
A cube beam splitter consists of two right-angle prisms cemented together, with a partially reflective coating on the hypotenuse of one prism to split or combine light.
Core Structure
A box-type or cube beam splitter is made by joining two triangular right-angle prisms along their hypotenuse faces to form a cubic shape . The internal hypotenuse surface of one prism is coated with a partially reflective material, which determines the reflection/transmission (R/T) ratio of the splitter. This coating can be dielectric for high efficiency or metallic (e.g., aluminum) for broadband applications .
Adhesive Layer
The two prisms are typically cemented together using optical adhesives such as epoxy, urethane, or polyester-based resins . The adhesive layer is carefully controlled in thickness to ensure proper splitting of light, often exploiting frustrated total internal reflection (FTIR) to achieve the desired 50/50 or other R/T ratios. Historically, natural adhesives like Canada balsam were used, but modern synthetic resins provide higher durability and optical performance .
Coatings and Optical Considerations
- Reflective Coating: Applied to the hypotenuse of one prism to partially reflect and partially transmit light.
- Anti-Reflection (AR) Coating: Often applied to the outer surfaces to minimize Fresnel reflections and ghosting .
- Polarization Control: For polarizing cube beam splitters, the internal coating and prism material are designed to separate S- and P-polarized light effectively .
Light Path Inside the Cube
When light enters the cube, it strikes the coated hypotenuse. Part of the beam is reflected at the internal interface, while the remainder is transmitted through the coating. The cube geometry ensures that both output beams have equal optical path lengths, which is critical for interferometry and other precision optical applications .
Summary
The internal components of a box-type beam splitter include:
- Two right-angle prisms forming the cube
- Partially reflective coating on the hypotenuse of one prism
- Optical adhesive layer bonding the prisms
- Optional AR coatings on external surfaces
- Material selection for polarization or wavelength-specific applications This design allows precise splitting or combining of light while maintaining optical path integrity and minimizing aberrations or ghost reflections .

In its most common form, a cube, a beam splitter is made from two triangular glass prisms which are glued together at their base using polyester, epoxy, or urethane-based adhesives. (Before these synthetic resins, natural ones were used, e.g. Canada balsam.) The thickness of the resin layer is adjusted such that (for a certain wavelength) half of the light incident through one "port" (i.e., face of the cube) is reflected and th
