A beam splitter T30/R70, also known as a 30/70 beam splitter, is an optical component that is designed to split an incident beam of light into two separate beams. The “T30” and “R70” refer to the percentage of the incident light that is transmitted and reflected, respectively.

In this case, the beam splitter reflects 70% of the incident light and transmits 30%. This makes it useful for a variety of applications in optics and photonics, such as in optical coatings, interferometry, and laser systems
