…fluorophores, with quantum efficiency often close to unity. Conversely, the confocal microscope is an optically inefficient system, where the confocal pinhole blocks as much as 99% of fluorescence collected by the objective, sacrificing image intensity for three-dimensional resolution. But choosing…

2. Pinhole Profilers
Pinhole profilers use a
small pinhole as the
aperture and plot the
transmitted power
versus position. The
resolution of the profile
is determined by the size
of the aperture. The
chief advantage of a pinhole profiler is…

…smaller pinhole is not sufficient to produce a usable profile, the
larger pinhole can be used--see "Pinhole Select" (p. 3-25). To
avoid deconvolution errors if the larger pinhole is used, the scan
lens is manually defocused to enlarge the beam diameter to be
six times the pinhole

…secured in a threaded adapter
A combination of microscope objective 20X and 10 micrometer pinhole provides
excellent beam quality and greater than 80% of the laser power after the pinhole.

…absorption process, the beam intensity drives the nonlinear effect only right at the beam waist (see Fig. 1). This eliminates the need to use a pinhole aperture to spatially filter out background light from the signal, as in one-photon confocal microscopy. A threedimensional image is built-up by…

…MPEF imaging and those
produced by single-photon confocal
imaging, Arrigoni confirmed, "Whereas a confocal microscope relies on a
pinhole (i.e., the `confocal aperture') to
block light generated away from the focal plane of the sample, a multiphoton
microscope excites…

dual axis knife edge scanners and a detector. The knife
edges provide the beam diameter data, while the pinholes
provide an intensity profile by which the ModeMaster is
aligned. This head is mounted on a five axis precision
positioner.

…from 30-50 nm is isolated using the configuration as outlined in Table 3.
Two filters are used to avoid any 800 nm
leakage through small pinholes that are
inevitably present in any thin metal filter.
Furthermore, since the throughput of these
filters decreases with time due…
