1550 nm Variable Optical Delay Line

Variable Optical Delay Line provides precision optical path variation of more than 15 cm (500 ps). The compact, rugged design makes the device ideal for integration in network equipment, test instruments, and optical for integration in network equipment, test instruments, and optical coherence tomography (OCT) systems for precision optical path length or timing alignment.
