Resolution vs depth of field
WebDec 30, 2024 · Optical Coherence Tomography (OCT) is an optical imaging technology occupying a unique position in the resolution vs. imaging depth spectrum. It is already well established in the field of ophthalmology, and its application in other fields of medicine is growing. This is motivated by the fact that OCT is a real-time sensing technology with … WebMar 27, 2024 · Stereo microscopes are always used to perform dissections of a specimen or sample, therefore, they can also be called dissecting microscopes. As stereo microscopes use 2 light channels, 1 for each eye, they give the observer a magnified, 3-dimensional view of the specimen or sample. This ability makes them practical to use for dissection.
Resolution vs depth of field
Did you know?
WebIf you want shallow depth of field, set a wide aperture (lower f-number), such as f/2.8 or f/4, and use a telephoto lens for maximum effect. If depth of field is not a critical factor in your composition, use an aperture of around f/5.6, f/8 or f/11. Your lens will usually give optimum performance at these settings. http://www.lithoguru.com/scientist/litho_tutor/Tutor44%20(Feb%2004).pdf
WebField emission scanning electron microscopy (FESEM) provides topographical and elemental information at magnifications of 10x to 300,000x, with virtually unlimited depth of field.
