Beamsplitter Coatings

Beamsplitter Coatings

A beamsplitter coating divides a single beam in light into two separate beams, often in a 50/50 split or some other ratio of transmission and reflectance. They can also recombine and manage multiple beam paths, depending on the application and control polarization. Beamsplitter coatings are crucial to many photonics applications, such as interferometry and fiber optic communications.

Beamsplitters can come in a multitude of geometries, from a single plate of glass that is skewed at an angle or in the form of cube in which two right angle prisms (for example) are mated together (either with optical adhesive or an adhesive free method) by their hypotenuses.  Beam splitters can be either non-polarizing (NPBS) or polarizing (PBS).  High extinction ratios (Tp/Ts; Rs/Rp) or more broadband applications are available.

Precision Optical offers a wide variety of beam splitters in the UV, VIS, NIR, and SWIR wavelength ranges.
