Melles griot 03 bsd 078 900-1300 nm beamsplitter cube
MELLES GRIOT BROADBAND DIELECTRIC CUBE BEAMSPLITTER
Cube beamsplitters consist of matched pairs of right-angle prisms cemented together. The hypotenuse of one prism has a partial reflection coating.
Cube beamsplitters have several advantages over plate beamsplitters: they are easier to mount; they are ideal for beam superposition; they exhibit less ghosting; and mechanical stress causes less deformation. Furthermore, the coatings are less likely to degrade over time because they are sealed into the body of the cube.
