This short introductory document is meant to explain the significance of the pinhole for those, who did not want to spend too much time to dig into theory and details of confocal microscopy but wanted to have an idea about the effect of the pinhole. https://www.leica-microsystems.com/science-lab/pinhole-effect-in-confocal-microscopes/ Wed, 26 Apr 2017 10:11:00 +0000 Dr. Rolf T. Borlinghaus https://www.leica-microsystems.com/17673 Confocal Microscopy Super-Resolution HyVolution – Super-Resolution Imaging with a Confocal Microscope Since the invention of the microscope, there has been continual discussion about the possibility of showing more detailed features of specimens as compared to just magnifying them. In this article we describe the HyVolution concept and how the combination of confocal multiparameter fluorescence imaging at the confocal super-resolution regime with psf-based real deconvolution allows high-speed multicolor imaging with a resolution down to 140 nm. https://www.leica-microsystems.com/science-lab/hyvolution-super-resolution-imaging-with-a-confocal-microscope/ Fri, 01 Apr 2016 07:19:00 +0000 Dr. Constantin Kappel, Dr. Rolf T. Borlinghaus https://www.leica-microsystems.com/9680 Confocal Microscopy Pinhole Geometry: Four Corners are Perfect Square and hexagonal pinholes provide identical image signal levels, if the geometries are compared in a sensible manner. The amount of light passing the pinhole depends on the area of that aperture, consequently the area is the parameter that must be compared when discussing brightness of focus images. The use of incommensurable edge lengths is meant to confuse the reader and thus dishonest and reprehensible. In this article, the signal level as a function of geometry and size in confocal microscopes is described. https://www.leica-microsystems.com/science-lab/pinhole-geometry-four-corners-are-perfect/ Thu, 23 May 2013 12:59:00 +0000 Dr. Rolf T. Borlinghaus https://www.leica-microsystems.com/3772 Confocal Microscopy Pinhole Controls Optical Slicing True confocal scanning microscopes (TCS) use a variable detection pinhole. Good optical sectioning tries to use just the inner core of the PSF. https://www.leica-microsystems.com/science-lab/pinhole-controls-optical-slicing/ Tue, 21 Jun 2011 22:00:00 +0000 Dr. Rolf T.
