A beamsplitter is an optic that splits light into 2 directions. Good fit for large beam size applications at a reasonable price. a laser beam) into two (or sometimes more) beams, which may or may not have the same optical power (radiant flux). It is a crucial part of many optical experimental and measurement systems, such as interferometers, also finding widespread application in fibre optic telecommunications. This division allows for the simultaneous analysis or utilization of the light's properties along two separate paths.
This photodetector monitors in-line power by diverting a controlled amount of light from the fiber core through a secondary waveguide. The waveguide directionally diverts the tapped light to an InGaAs photodiode, preventing back reflections from the detector propagating back. Thorlabs' Inline Photodetector is used for real-time monitoring of the optical power being transmitted through a fiber. Our photodetectors feature sensors that enable properties such as intensity, power, intensity distribution, wavefront shape, energy, and wavelength to be measured.
