A beam splitter T70/R30 is a device that splits a beam of light into two parts, with 70% of the light passing through and 30% of the light being reflected. The T70/R30 notation indicates the transmittance and reflectance of the splitter, respectively.

Beam splitters are commonly used in optical experiments and instruments, such as interferometers, microscopes, and spectrometers. They can also be used in photography and video production to split a single image into two or more images.
