Beamsplitters

Depending on the application, the beamsplitter can be either a flat beam splitter or a prism beamsplitter. The advantage of dielectric film beamsplitters is that the absorption rate is low, which is almost negligible; The defects are the narrow spectral range, the polarization is pronounced, and the perspective effect is remarkable. For metal beamsplitters, the advantages are good neutrality, wide spectral range, and small polarization effect; The defect is that the absorption is large and the threshold is low. Pay attention to the direction of the incident light. A beam splitter is an optical element that splits a beam of light into two beams based on a certain ratio of reflection and transmission. It is widely used in laser optical systems, illumination optical systems and spectrometer optical systems.
