Picosecond fluorescence lifetime measurement system C11200 - 2

Directly captures temporal variations of laser-excited fluorescence with 1 ps resolution. Photoluminescence which is represented by fluorescence, phosphorescence, or delayed fluorescence is one of the energy release processes to be observed when molecules return from the excited state to the ground state. Measurement of photoluminescence decay with an ultra-fast pulsed excitation light is generally called as fluorescence lifetime measurement and studied to reveal various dynamics of excited molecules. Recently, development of various kinds of materials such as organic/inorganic phosphors,...

Picosecond fluorescence lifetime measurement system C11200 - 3

Fluorescence phenomena at multiple wavelengths can be measured simultaneously. Features 1 ps temporal resolution The system uses a streak camera that can achieve a temporal resolution of 1 ps. 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...

4 Detector, Input optics, Output optics, Readout camera The heart of the C11200 system is an ultrafast optical detector - the universal streak camera C10910. It can capture very weak luminescence phenomena, from picoseconds to milliseconds, achieving very high signal-to-noise ratio within short measuring times due its high repetition rates of up to 165 MHz. The spatial axis of the C10910 allows multichannel spectral measurement, making it the ideal detector for time-resolved spectroscopy. The system is completely remote-controlled from the data analyzer. Universal streak camera C10910 Input...
