Laser Scanning Microscope Magnification And Resolution

In some cases specimens should be sampled at more than 2 3 times the highest information frequency to allow for the possibility that the highest frequency was misjudged.

Laser scanning microscope magnification and resolution.

This means that we can view visual sections of tiny structures that. The laser scanning microscope uses a scanning design called beam scanning where the laser image path is scanned in a raster pattern on the surface of the sample. In the confocal laser scanning microscope the highest frequency to be sampled f is imposed by the optical system and for a particular resolution specification. With confocal laser scanning microscopy clsm we can find out even more.

Relatively thick specimens can be imaged in successive volumes by acquiring a series of sections along the optical z axis of the microscope. Effect of laser scanning speed on image resolution. The confocal laser scanning microscope. Capturing multiple two dimensional images at different depths in a sample enables the.

It uses a 670 nm red wavelength helium neon. Clsm combines high resolution optical imaging with depth selectivity which allows us to do optical sectioning. This first generation instrument images corneal structures at 400 magnification and has a field of view of 400 400 µm when used with a 63 objective lens that has a numerical aperture of 0 9. Fluorescent microscopy not only makes our images look good it also allows us to gain a better understanding of cells structures and tissue.
