The ODL220/M from Thorlabs Inc is an Optical Delay Line that provides a maximum optical delay of 1470 ps. It has an inherent delay of 507 ps (at 0 mm) and a delay sensitivity of 0.67 fs with a travel range of 220 mm (8.6 inches). This ODL produces an output beam that is 81.7 mm (3.2 inches) in height and has a maximum speed of 300 mm/s with an acceleration of 5000 mm/s2. This ODL uses a brushless DC motor and includes a DC servo stage, controller, precision linear bearings, and retroreflector optics with mounts. It can be controlled via a 16-Bit digital PID servo loop with velocity and acceleration feedforward.
The ODL220/M includes two drop-in irises with four mounting positions. It uses UM10-AG Ultrafast-Enhanced Silver Mirrors and MRAK25-P01 Protected Silver Knife-Edge Right-Angle Prism Mirror to provide high reflectance in the spectral range of 750 - 1000 nm and minimal group delay dispersion making these systems well suited for use with femtosecond pulsed lasers. This ODL requires an AC supply of 100 - 240 V and consumes 250 W of power. It is available in a module that measures 199.8 x 229.1 x 108.8 mm.
