MDL-003 Fiber Optic Delay Line
Product information "MDL-003 Fiber Optic Delay Line"
840-1650 nm; Delay Range 0-100, 0-200 ps; RL 55 dB; Fiber Type SMF-28, HI780, HI1060, PM Panda; IL 1 dB; PDL 0.15 dB
General Photonics’ motorized variable optical delay line is the smallest delay line in the MDL series of products, with a total volume of less than 2 cubic inches. The MDL-003 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 MDL-003 motorized variable optical delay line has a delay range of 100 ps; however an internal mirror can be installed to double pass the light, thereby doubling the delay range. The device uses a stepper motor and dual position sensors for precise control. A small controller board is available as an option.
