Picosecond Fluorescence Lifetime Measurement System |
| Brief description |
A system for time-resolved fluorescence spectroscopy with a temporal resolution (IRF) of approx. 15 ps |
|
Full description |
|
The Hamamatsu Picosecond Fluorescence Lifetime Measurement System has been developed in response to the requirements of researchers studying photofunctional materials. The system uses a "streakscope", a kind of optical transient recorder with picosecond time response, realizing ultra-fast time-resolved spectrophotometry. The use of streak camera technology allows photon-counting detection sensitivity as well as simultaneous multi-channel time / wavelength measurements. |

Features |
- 5 ps time resolution. The "streakscope" detector has an IRF of approx. 15 ps. Through deconvolution processing, lifetimes as short as 5 ps can be measured with ease.
- 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 measured with high efficiency, a feature not available by other methods.
- A wide dynamic range better than 10,000 : 1. Measures very-low fluorescence with a dynamic range better than 10,000 : 1. This allows the analysis of multi-component fluorescence lifetime with high accuracy.
- Measures fluorescence lifetime with a good S/N ratio in a short period. The streak sweep can be operated at up to 2 MHz. Through integration of this high-speed repetitive sweep, measurement with a high S/N ratio can be carried out in a short period.
- 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.
- Covers a wide wavelength range from UV to infrared. Three streakscope models are available, with sensitive ranges of 200 to 850 nm, 400 to 900 nm, and 300 to 1500 nm.
