The Hamamatsu Picosecond fluorescence lifetime measurement system has been developed in response to the requirements of researchers studying such materials. The use of a "streak camera", an optical transient recorder with picosecond time response, makes ultrafast time-resolved spectrophotometry a reality.
The use of streak camera technology allows detection sensitivities in the photon counting region. For simultaneous wavelength and time measurements, a spectrometer can be added to the system. Measurement parameters such as wavelength and time settings are controlled by a computer for simplified laboratory use.
● 5 ps temporal resolution
The system uses a streak camera that can achieve a temporal resolution of 15 ps. Through deconvolution processing, a temporal resolution of 5 ps is obtained.
● Simultaneous multi-wavelength measurement
Time-resolved spectrum is acquired in a very short time since fluorescence lifetimes are measured over multiple wavelengths without scanning.
● Two-dimensional photon counting
Ultra-high sensitivity and simultaneous multiple-wavelength measurement capabilities are realized by the combination of photon counting and streak camera techniques. Because fluorescence phenomena at multiple wavelengths can be measured simultaneously, even very-low fluorescence can be detected and measured with high efficiency, a feature not available with previous methods.
● A wide dynamic range better than 100 000:1
Measures very-low fluorescence with a dynamic range better than 100 000:1*. This allows the an analysis of multi-component fluorescence lifetime with high accuracy. *Specified value by streak camera S-20 C10627.
● Measures fluorescence lifetime with good S/N ratio with short integration time
The streak sweep can be operated at up to 20 MHz. Through integration of this high-speed repetitive sweep, measurement with a high S/N ratio can be carried out quickly.
● Covers fluorescence phenomena from picoseconds to milliseconds
Because the sweep time can be varied from 1 ns to 10 ms, a wide range of fluorescence lifetime measurements from picoseconds to milliseconds is possible. For higher temporal resolution, an universal streak camera is optional selection.
● Covers a wide wavelength range from UV to NIR
Two streak camera are available, with sensitive regions of 200 nm to 850 nm or 400 nm to 900 nm. NIR streak camera is the optional for the measurement from 1000 nm to 1650 nm.
