Product Description
- Picosecond resolution time measurement system
- Powerful data processing software offering multiple measurement modes
- Provides various counting channel options
LBTEK's Single Photon Counter is a high-precision time measurement system capable of ultra-sensitive single-photon-level detection of weak optical signals measured by the detector. It also supports time-tagging mode, enabling real-time recording of the temporal information of detected signals. This technology domain encompasses multiple technical aspects including signal processing, photoelectric detection, and software operation, allowing for precise measurement of time intervals between multiple signal events with a time resolution reaching the picosecond level. With powerful high-speed data storage and processing, the LBTEK single-photon counter can achieve a saturation count rate of up to 500 Mcps. Combined with high-speed signal transmission technology and processing software, this system can be applied in various fields such as fluorescence lifetime measurement, laser ranging, fiber optic sensing, quantum optics, nuclear physics, and oceanography.
Time-Correlated Single Photon Counters
- Counting channels support 1、4 or 8
- Supports 16 ps time resolution with a saturation count rate up to 100 Mcps
- Provides optional histogram mode and time-tagging mode
The LBTEK Time-Correlated Single Photon Counter measures photon signals detected by single-photon detection devices across multiple signal cycles, obtaining a large number of photon counting signals and time information. By superimposing these measurement results on the same time coordinate, a histogram based on statistical results can be plotted. The histogram bins reflect the light signal intensity corresponding to the count values within the time window. Additionally, the LBTEK Time-Correlated Single Photon Counter supports time-tagging mode, enabling real-time recording of the time information and channel information of the acquired signals. The LBTEK Time-Correlated Single Photon Counter offers a time resolution of 16 ps and a dead time no longer than 10 ns. With powerful high-speed data storage and processing capabilities, it achieves a saturation count rate of up to 100 Mcps. Data is uploaded to the PC via a USB 3.0 interface, allowing for operations such as histogram construction, fitting, parameter setting, data storage, and analysis.
