Optical delay stage
Webtrains were temporally adjusted by an optical delay stage and coupled into the setup by dichroic mirrors (Fig. 1a). The duration of the visible pulses was 0.2 ps to ensure temporally defined excitation of the fluorophore. The near-infrared STED pulses were stretched by a grating to t5 40 ps. This allowed us to extend STED over a time period ... Web4 III. ADMINISTERING THE TEST Turn the power on by depressing the red power switch. Depress the two eye switches--orange and green, being sure the white switch (day/night) …

WebThorlabs' motorized stages include linear translation stages with up to 600 mm of travel, rotation mounts and stages, goniometers, pitch and yaw platforms, and high-resolution multi-axis platforms. Our stages feature a variety of motors, including stepper, DC servo, direct drive, piezo inertia, and resonant piezo motors. WebJun 23, 2024 · The maximum optical delay the V-508 stage can provide is 1668ps, larger PI linear stage models can achieve up to 8000 picoseconds. Why Small Time Increments Matter? Time-resolved, ultrafast spectroscopy allows a very close and precise look at dynamic processes in materials and chemical compounds.
WebOptimized Delay Stages for Spectroscopy THz-TDS benefits from the newly released DL series delay line stages, which are ideal for ultrafast spectroscopy due to the fast speed, acceleration, and repeatable positioning. The standard maximum optical delay between pump and probe in THz-TDS is 4.3 ns.
