pco.flim

luminescence lifetime imaging camera

The pco.flim is the first Frequency Domain FLIM camera using a two tap CMOS sensor. Synchronized modulation of pixels and stimulated light enables you the analysis of luminescence decay times in the range of 100 ps – 100 µs.

With its 1008 x 1008 pixels resolution the pco.flim reads out 45 double frames/s at a max. You can use it for a modulation frequency range of 5 kHz – 40 MHz.

Using C-mount as standard the system is easy to connect to any microscope or lens. Further, the USB 3.0 interface lets you connect the camera to all kinds of computers. This saves you significant efforts and costs for operation and research.

The pco.flim laser is a homogeneously illuminating light source designed for use with the pco.flim. It features a digital modulation frequency range of 0 – 250 MHz. You can either order the pco.flim laser for widefield epifluorescence microscope illumination, or for Total-Internal-Reflection-Fluorescence (TIRF) microscopy, light sheet fluorescence microscopy (LSFM) and confocal spinning disk microscopy.

Choose between a wide range of different wavelengths and light output powers. The laser is ideally suited if your relevant luminescence lifetimes are in the range of a few nanoseconds. In case you are using a Nikon microscope, the Nikon double-safety-shutter option is also available

应用案例：

Figure 1: The left photo shows the fluorescence intensity of HEK-293 cells which expressed a CFP/DJ-1 protein as control of a FRET experiment. The middle image shows the phase angle derived distribution of fluorescence lifetimes in the range of 0 – 4 ns (imageJ LUT 16 colors, colorbar 0 – 4 ns) which has been masked by an intensity filter. The range of lifetimes around 2 ns was found in all of the 26 cells, which have been measured and showed about 10% FRET efficiency compared to the pure CFP expression. The right image shows the lifetime distribution image weighted by the fluorescence intensity image (the color images are false color coded using the same colorbar and LUT) without mask (courtesy of Prof. Dr. F.S. Wouters and Dr. G. Bunt, University Medicine Göttingen).

The visible marker is Alexa Fluor® 488 wheat germ agglutinin, a green-fluorescent lectin, which was used to label elements of the glomeruli and convoluted tubules, which were excited with 488 nm at a modulation frequency of 30 MHz. The left image shows the fluorescence intensity of the mouse kidney sample (20x air objective). The middle image shows the phase angle derived distribution of fluorescence lifetimes of the Alexa Fluor 488® in the range of 1.5 – 3.5 ns (NIS Elements, colorbar 1.5 – 3.5 ns). The right image shows the lifetime distribution image weighted by the fluorescence intensity image
