Halcyone is an all in one box fluorescence measurement system comprising a Fluorescence Upconversion spectrometer and a Time-Correlated Single Photon Counting (TCSPC) instrument. In the upconversion mode Halcyone has a time window of 3.3 ns with femtosecond time resolution. In the TCSPC regime the time window can be expanded up to 1 ms with 200 ps resolution. Switching between the two modes is very straightforward and there is no requirement to change the optical setup. A supplied 2-D camera unit is employed to ensure highly precise delay stage alignment. The spectral range of Halcyone covers the visible and the near infrared regions. It can work with either a mode locked Ti sapphire oscillator or with a regeneratively amplified Ti:sapphire laser, both of which are to be supplied by the user.
Features:
- Spectral Range: Upconversion mode: 350-1600 nm TCSPC mode: 160-650 nm or 400-900 nm
- Time Window: standard - 3.3 ns (Upconversion Mode); 12ns-1ms (TCSPC mode)
- Fluorescence Anisotropy measurements
- Optional reflection mode
- Optional 2D translating sample holder for solid samples
- Computer controlled spectral and kinetic scanning for 3D data surfaces

Spectral Coverage:
• Upconversion mode: 400-1600 nm
• TCSPC mode: 160-650 nm or 260-900
nm
Time window:
• Upconversion mode: 3.3 ns
• TCSPC mode: determined by time
interval between adjacent laser pulses.
Typical values for femtosecond oscillators
– 12 ns; for femtosecond amplifiers
– 1 ms.
Temporal resolution:
• Upconversion mode: ca 1.4 times
longer than the laser pulse duration.
• TCSPC mode: 200 ps
Intrinsic Time Resolution:
• Upconversion Mode: Standard - 7 fs
• TCSPC mode: 200 ps

|
Fluorescence Anisotropy:
• Halcyone contains all necessary hardware to perform fluorescence anisotropy measurements.
Optional:
• 2D translating sample holder for solid samples.
Dimensions:
• W24” x L36” x H10”
(W610 x L915 x H250mm)
Software:
Halcyone comes with complete data acquisition software that is capable of obtaining full spectral and kinetic data sets. The data can be saved as either a single wavelength time profile, a transient spectrum at a particular probe delay (time point), or as a full time-wavelength-intensity surface that can be analyzed with Surface Xplorer. Otherwise, single spectral and kinetic profiles can be processed with third party software.

The Hacyone upconversion system
is easy to use. The team at Ultrafast
Systems is willing to work with
your individual needs. If I for
any reason have difficulty in obtaining
a desired signal, they have also
been willing to troubleshoot the
problem with me until I can get
the data I need.

Both HELIOS and HALCYONE are easy to align even if you are not a big expert so you can save time to collect many data that you can analyze with the support of the very well done software Surface Xplorer Pro.
Moreover technicians are always in contact with you to solve all the problems. Thank you. |

| Apollo |
|
Femtosecond Harmonics Generator with outputs at the fundamental, 2nd and 3rd harmonics of the Ti:Sapphire laser output. |
| Transport Optics |
|
Transport optics kits for routing the laser output to our spectrometers. |
| Surface Xplorer |
|
The Surface Xplorer software makes working with 3D time-resolved data fast and efficient. It combines strong presentational features including simultaneous 3D and 2D data display with powerful data analysis capabilities such as nonlinear fitting, SVD and Global Analysis. |
| Beam Alignment Tool |
|
This device is designed for monitoring beam pointing stability and beam collimation in femtosecond spectrometry experiments where variable optical delay stage is used. Includes: camera assembly (USB 2.0) and control software. This item is supplied standard with Halcyone. |
| 2D Translating Sample Holder |
|
A motorized computer-controlled 2-D sample holder for shifting the excited region during the experiment can be supplied as an option. This is useful for examining solid samples that may suffer photo-degradation during laser excitation. The maximum translation area is ~120 mm2 and the motion is controlled automatically by LabVIEW-based software. |
