Applications:
|
Streak tube |
Photonis bilamellar family: These sealed tubes use bilamellar optics to provide an ultrafast temporal resolution whilst maintaining excellent spatial resolution. |

| Digitizer | 16 bits |
| Coupling to streak tube | 1:1 Fiber optic taper |
| Cooling | 15-20 °C cooling water is required for the CCD camera |
Operation modes |
|
| Normal sweep | The sweep starts out of the screen, crosses the whole screen and ends outside the screen. |
| Timing mode | The sweep starts in the screen and ends also the screen. It is used to synchronize the streak camera to the event. |
| Focus mode | A static voltage is applied to position the trace close to the center of the screen. The sweep trigger is disabled. This mode is used to adjust the incident light into the streak camera. |
Offered configurations |
Single enclosure

General |
|
| Electrical input | Universal AC, 110-240V, 50-60 Hz |
| Certification | CE |
| Tests and Calibration | Before shipping, each system is tested on a femtosecond laser at the Advanced Laser Light Source (Canada) |

Options |
||
| Blanking circuits | With the blanking option, streak tube is blocked during the time the signals sweeps back to its start position. This feature is required when the optical signal lasts longer than the sweep range. | |
| Liquid chiller | Liquid chiller and plumbing to cool the CCD camera. | |
| Remote control over Ethernet | Web-based user interface to operate system via Ethernet 10BASE-T, 100BASE-T, 1000BASE-T on RJ-45 connectors. | |
| Remote control over Optical Ethernet | Web-based user interface to operate system via optical Ethernet 1 Gb/s (1000 Base SX) on 2 SMA 905 connectors (or other common fiber optics standards). | |
| Laser-triggered sweep unit for CPA lasers |
Because of its sub-picosecond jitter, this unit allows the analysis of ultrafast events at repetition rates up to 10 kHz while conserving the excellent spatial and temporal resolution of the AXIS streak camera. This is the ideal tools ultrafast spectroscopy with large dynamic range and high signal-to-noise ratio It requires about 100 µJ per laser pulse. |
Only a fraction of the laser energy is taken to trigger photoconductive switches. This allows signal averaging over a large number of laser shots. |
The signal is averaged over 1 million shots (~ 20 minutes) and time resolution is still subpicosecond. |

| Custom input optics | Custom designed optical setup that accommodate special needs. | |
| Timing fiducial input fibers | This assembly allows recording of two timing optical pulses, one at each end of the slit. These pulses are sent through optical fibers. This is for absolute time referencing and to measure absolute sensitivity on each shot. | |
| Slow scan mode | Operation mode in which the sweep crosses the whole screen in 0.5 second. It is used to characterize spatial non-uniformity in the instrumental response by illuminating with a constant brightness light source. | |
| 24V supply | To power the whole system with a DC voltage between 23V and 28V. | |
| Spectrometer | Custom spectrometer that fits special needs. | |
