LUNA’s motorized variable optical delay line provides low cost, precision optical path length adjustment and delay scanning functionality. This addition to the MDL product line is specifically designed for OEM applications that require continuous scanning capability and a small footprint. The standard device has a delay range of 100 ps.
An internal mirror can also be installed to
cause light to double pass the device : doubling the delay range. A stepper motor and two position sensors ensure precise delay control. Low insertion loss and high reliability make this device ideal for integration in optical coherence tomography (OCT) systems, network equipment and test
instruments for precision optical path length control or timing alignment. A mini controller board is available as an accessory.
Applications
• Optical Coherence Tomography (OCT)
• Optical Fourier spectrum analysis
• Optical interferometry
• Delay generation and measurement
• Optical time division multiplexing (OTDM)
• Fiber sensors
