Broadband Fiber-Optic Couplers for OCT

Optical Coherence Tomography (OCT) systems require components that operate
over a broad spectral range, with minimal spectral dependency. Thorlabs OCT
proven couplers are tested to ensure minimal wavelength dependent insertion loss
variations, making them an ideal choice for integrating into many OCT systems.
