选配件 | |
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 laser | Because of its sub-picosecond jitter, this unit allows the analysis of ultrafast events at repetition rates up to 5 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. |
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电源 | To power the whole system with a DC voltage between 23V and 28V. |
光谱仪 | Custom spectrometer that fits special needs. |
