Laser confocal scanning microscope

There are also laser-scanning confocal microscopes rapidly overtaking the TSM as a means of confocal microscopy. There is also a computer software program that produces a "confocal" image by recogni2ing the shapes of out-of-focus detail, ie, halos, and subtracting these from the in-focus image.

Fluorescence of secretory structures may be seen and measured by various technique from simple luminescent microscope and complex laser scanning confocal microscope to microspectrofluorimetry described in this chapter.

P 82] Dilution-type mixing was accomplished with the fluorescent dyes acridine orange (0.01% solution in 20 mM in TE buffer see below) or trypan blue (prepared in 0.85% saline) contacted with buffer solution (TE buffer 10 mmol f4 Tris-HCl, pH 7.4, 1 mmol 1 1 EDTA, pH 8.0) [164]. Images were taken by a laser scanning confocal microscope. Profiling data analysis was employed along detection lines. 

Of the five probes evaluated only Probes 1, 3, and 5 were worth evaluating in detail, as the others had small Stokes shift (excitation wavelength, /v, minus emission wavelength, /Vln) or no detectable emission. Fluorescence behavior was measured using a Zeiss LSM 510 Laser Scanning Confocal Microscope (LSCM) and an Ocean Optics USB2000 spectrometer. 

These fluctuations also occur when there are temperature or instabilty problems in the Acousto Optical Transmissions Filter (AOTF) of Laser Scanning Confocal Microscopes (LSCM), or when there is incorrect...

Laser scanning confocal microscope A fluorescence microscope achieving improved depth discrimination and contrast by blocking fluorescence that originates outside the plane of focus by use of a confocal pinhole. 

One limitation, however, is that only a limited number of spots can be measured simultaneously. A compromise between the temporal analysis of FCS and fluorescence fluctuation analysis in the spatial domain [39] can be obtained by exploiting the time structure of sample/laser scanning confocal microscope images [40,41]. Thereby, spatial correlation analysis of the emitted fluorescence is combined with temporal characterization of the fluorescence emission from the serial data stream of subsequently scanned pixels. This...

Confocal laser scanning microscopy. A laser scanning confocal microscope system was used to analyze the microstructure of the fdm components and films A model IRBE (inverted) microscope (Leica Microsystems, Bannockburn, IL) with a universal stage and 20X objective lens was coupled to a TCS NT/SP scanner head (Leica Microsystems, Exton, PA). Sheets of samples or powders in MatTek dishes (MatTek Corp., Ashland, MA) were illuminated with the 488 nm line of an Argon laser and fluorescence was collected in one channel (520-580 nm) and reflection at 488 nm was collected in another. Fluorescence emission spectra for the sample powders of SFP and Pectin were collected in the range of 500-680 nm.
