Beamsplitters are used for separating or merging light beams. The two common forms Z-OPTICS LIMITED offers are Plates and cubes.
Cubes are a simple, safe shape for applications with low power rates. The efficiency of beamsplitters depends largely on the parameters for the coating.
The type, coating, transmission range and damage threshold should be taken into consideration when choosing beamsplitters.
