Multicube™ components ensure highly rugged and warp-resistant setups, especially for single-mode (PM) fiber coupling. The multicubes™ are combined and fixed using four Ø 6 mm rods in parallel and are compatible with established cage/microbench systems. The multicube™ construction system is the perfect integration platform for laser beam couplers, beam combiners, beam splitters, polarizers or retardation optics. Self-supporting modules and laser beam assemblies can be created that are extremely resistant to torsion and contain complementary components.
