Optical delay line (ps/mm range) / Optical delays
Manage your optical delay from 1 ps to 150 ps with custom optical delay lines
Optical delay line (ps/mm range) summary
IDIL Fibres Optiques manufactures manual and motorized variable optical delay lines (ODLs). Manual optical delay lines tunability depends on a micrometric screw which allows a higher than 0.1 picoseconds resolution. The translation stage can also be motorized and easily controlled by a computer via an USB interface. In fact, according to the translation stage, we propose a tunability :
- up to 80 ps for ODL 25
- up to 150 ps for ODL 50
- or from 1 ps to 150 ps for Custom ODL
Furthermore, packaging dimensions vary in accordance with customers’ requirements regarding delay values: 30 x 80 x 70 mm³, 100 x 81.4 x 40 mm³, 280 x 200 x 76 mm³.

Contents (motorized ODL): User guide, calibration data, USB cable, power supply, integrated collimator, input and output fiber
Fiber Optic Delay Lines (ODL) consist of controlling the delay through the device by varying the distance the light travels between the input and the output fiber collimator. IDIL expertise in single-pass ODL allows a higher than 0.1 ps resolution compared to other supplier. Double-pass are available on request.
