General Optics
Beamsplitter Cubes
Split and recombine laser beams or broadband sources with these beamsplitter cubes that offer both polarization insensitivity and high throughput.
Coherent non-polarizing beamsplitter cubes use a metallic–dielectric coating that maintains transmission and reflection of the s- and p-polarization states to within 5% of each other, thus minimizing the polarization sensitivity of an optical system.
