Ultrafast Systems

An optical delay line is a critical element of any ultrafast pump–probe (or pump–gate) set-up. Even a small change in the beam pointing (laser beam drift, moved mirrors, etc.) can compromise the quality of your data. This is why it is recommended to check the delay line alignment at least once a day. Alignment of the delay line normally requires special technical training and can be time consuming.

Ultrafast Systems’ patented Smart Delay Line™ system (Patent no.: US 10,209,131) fully restores the original alignment of your delay line in a few minutes. Very importantly, the original beam pointing after the delay line gets restored as well. This ensures that the optical setup “downstream” from the delay line will not require re-alignment. This significantly shortens the time needed to set up an experiment allowing for more up-time of the instrument. Additionally, this reduces the amount of technical training necessary for a user, thus making the spectrometer accessible to a larger group of researchers.

Ultrafast Systems’ Helios and Eos transient absorption spectrometers allow to monitor photo-induced absorbance changes without any gaps in coverage from UV to mid-IR over time windows from picoseconds to microseconds and beyond.

Ultrafast Systems has a comprehensive solution for measuring time-resolved fluorescence across a broad spectral range from UV to IR and over time windows from picoseconds to microseconds and beyond.

Ultrafast Systems’ high speed spectrometers work across a broad spectral range (UV-VIS – NIR – SWIR) and are designed to maximize the light throughput. They consist of an imaging spectrograph and a high-speed multichannel detector. The spectrograph utilizes a high-efficiency, ion-etched, aberration corrected holographic grating. After an optical fiber, light travels directly to the grating. The grating simultaneously disperses and refocuses light onto the sensor without the use of any additional mirrors, lenses, etc. The height of the projected spectral image remains virtually the same as the diameter of the input optical fiber, ensuring minimal losses at the sensor. The multichannel detectors have 0.5 mm tall pixels, which are optimal for spectrometry.

Ultrafast Systems’ IRIS is a continuously tunable picosecond excitation source with a variable bandwidth. This standalone, computer-controlled laser delivers ca 100 ps pulses from the UV to the NIR at high repetition rates, which is ideal for many time-resolved luminescence experiments. When coupled to Ultrafast Systems’ Halcyone, IRIS pico provides a versatile all-in-one TCSPC instrument.
