选配件 | |
条纹管 | Other streak tubes in the Photonis product line are available. For example, some of them allow 1000 spectral resolution points with a compromise on time resolution. |
光阴极 | S20, S25, and S1 cathodes are available |
光栅 | Standard system comes with a 150 gr/mm grating. The turret can accommodate 3 gratings. Therefore 2 more gratings can be added. Available gratings are 150 gr/mm, 300 gr/mm, 600 gr/mm and 1200 gr/mm. They come with different blaze wavelength (300nm, 500nm, 800nm, 1µm). |
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. |
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.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. |
