AuraTek Multi-Anode Detector Family

The AuraTek product family adds two new multi-anode detectors and one multi-anode photon counting system to the Photek suite of products distributed by Sydor in the United States. Each of the detectors feature MCP-based PMTs and provide users with high density spatial and temporal information. Suggested applications include: high content screening, time resolved spectroscopy, wide field time correlated single photon counting, FLIM, FRET, LIDAR, wave shifting fiber readout, and microplate readout, to name a few. These new PMTs demonstrate 430 ps FWHM pulse width, transit time spread of <40ps, and are immune to magnetic fields.

Sydor Pulse Dilation PMT (PD-PMT)

Sydor’s Pulse Dilation PMT (PD-PMT) uses a custom circumferential photocathode pulser coupled to an expanded PMT tube to magnify the time resolution of our fastest 100 ps PMT to under 10 ps. This expanded time resolution is maintained even when using a relatively slow and less expensive oscilloscope readout system with only 2 to 6 GHz capability. This PD-PMT offers extreme performance, but with the ease of simple and robust operation. The resulting expansion enables the use of inexpensive readout electronics for applications that otherwise would require expensive high-performance electronics. The PD-PMT brings new capabilities to Cherenkov measurements, gamma reaction history, time of flight, luminescence, and other experiments where a high temporal resolution window is required.

photodiodesPhotek photodiodes are used for detecting ultra-fast optical events. Photodiodes generate an electrical output when illuminated by light and have no internal gain but can work over a large dynamic range. Our Photodiodes have a rise time of less than 100ps and are available with either a 10 mm, 25 mm or 40 mm photocathode. These photodiodes can be used for examining sub-nanosecond optical pulses, optical triggering, and nuclear research applications.

Vacuum Imaging Detection (VID)

3d_vidPhotek Vacuum Imaging Detectors (VIDs) are open-face detectors without a photocathode. VIDs are designed to be mounted into or onto a vacuum chamber to detect charged particles, UV photons and neutrons. Our Vacuum Imaging Detectors are available with either a phosphor screen, solid anode or resistive sea which provides re-configurable anode options. The phosphor screen can also include a time-of-flight module with timing response to 5 ns. These VIDs are typically used in electron microscopy, nuclear physics research, mass spectrometry, molecular disassociation, space telescopes, and VUV imaging.

Velocity Map Imaging (VMI)

vmi-setupVelocity Map Imaging (VMI) is a powerful experimental technique used in laser physics and physical chemistry research to investigate gas phase ionization, fragmentation dynamics, photoelectron spectroscopy and much more. VMI provides details on velocity, angular distribution and mass of charged particles, offering more complete information than many standard ion imaging and spectrometry techniques.

Velocity map imaging is becoming an even more popular technique in research laboratories worldwide, due to advances in charged-particle detection and laser technology. Photek has collaborated with internationally-renowned physical chemists and laser physicists, to develop a range of VMI instrumentation and accessories to provide advanced velocity map imaging capabilities.
