Project Description

AXIS-SV: High-Sensitivity Visible-IR Streak Camera

AXIS-SV is a high sensitivity streak camera that can sweep 200 points (10 mm slit) with a time resolution of 4 ps (FWHM). It integrates a streak tube, a high-sensitivity TE-cooled CMOS and an internal computer. It’s a standalone solution for complex scientific experiments.

STREAK TUBE

This streak camera uses a P900 PHOTONIS streak tube built according to high quality standards and features:

  • Picosecond time resolution
  • High spatial resolution
  • Integrated input slit (no need for a mechanical slit)
  • Ruggedized for harsh environment

It can be built with different cathodes and matched with the experiment for optimal throughput:

OPERATION MODES

streak camera-normal-mode Normal sweep
The sweep crosses the whole screen and ends outside.
streak camera-timing-mode Timing mode
The sweep always remains in the screen. It is used to synchronize the streak camera to the experiment.
streak camera-focus-mode Focus mode
The slit image is positioned at the center of the screen. The sweep trigger is disabled. This mode is used to align the experimental setup and to adjust the incident light level.
