Product information "VDL-004 Fiber Optic Delay Line"
840-1650 nm; Delay Range 0-130 ps (4 cm); RL 55 dB; Fiber Type SMF-28, HI780, HI1060, PM Panda; IL <0.8 dB; PDL 0.1 dB
General Photonics’ VDL-004 module is a miniature variable optical delay line designed specifically for OEM applications. This device offers continuous control with high precision, zero backlash, and good thermal stability.
An internal mirror can be installed to cause light to double pass the device, doubling the delay range. A locking mechanism is provided for locking the delay at a permanent position. The VDL-004 delay line module generally comes with single mode (SM) or polarization maintaining (PM) fiber pigtails per customer requirement.
With a footprint of only 78 x 22 x 15 mm for a delay range of 130 ps (40 mm), the device can be easily integrated into larger instruments or assemblies for precision optical path length control or timing alignment. Convenient mounting brackets allow mounting in any orientation, as well as easy integration of multiple units on a base plate to form an array.
