A beamsplitter with a T50/R50 specification means that it splits the incoming light into two paths, with 50% of the light transmitting through the beamsplitter (T50) and 50% of the light reflecting off the beamsplitter (R50).

This type of beamsplitter is commonly used in optical systems where the incoming light needs to be divided into two equal parts with one part being used for measurement or detection, and the other part being used for imaging or illumination.
