Oculars is an alternative name for eyepieces that has been widely used in the literature, but to maintain consistency during this discussion we will refer to all oculars as eyepieces. ... http://microscopecameraadapters.com/microscope-camera-adapters/photo-eyepieces-for-large-cameras/ Filter thread sizes are important to microscope adapters, because it is often much cheaper to make a custom adapter with a larger thread size than the camera provides. This is due to the difficulty of machining precision threads up to a shoulder, versus machining threads on the outside of a ... http://microscopecameraadapters.com/microscope-camera-adapters/understanding-standard-filter-threads-and-adapters/ The C-mount standard is a widely-used method of connecting small cameras to lenses, such as mounting a lens on an industrial camera, or for connecting trinocular phototubes on microscopes to cameras. The "C" is said to stand for "cine", the original application being movie camera lenses, such as were made ... http://microscopecameraadapters.com/microscope-camera-adapters/understanding-c-mount-and-cs-mount-standard-mechanics-optics-and-cameras/ The Ramsden disc also called Ramsden circle produced by the microscope eyepiece is the circular field image formed some distance the vertex or eye-relief distance above the top of the eyepiece. A good eyepiece forms a Ramsden disc equal to or larger than the size of the pupil of the ... http://microscopecameraadapters.com/microscope-camera-adapters/understanding-and-avoiding-vignetting/ We’ve had inquiries about what consumer or presume digital cameras are good for adapting to photomicrography. Some criteria of desirability are accessory threads that permit flush mounting of an adapter - Most current digital cameras such as the compact consumer types don't have them. Some cameras with turret type lenses ... http://microscopecameraadapters.com/microscope-camera-adapters/selecting-a-camera-for-digital-photomicrography/ This page describes the custom adapters made to fit a variety of cameras, microscopes, and medical instruments, for most of these adapters, they are $85 to $175, depending on the complexity. Old and new optical instruments are thereby fitted into the modern age of digital imaging. Besides the mechanical attachment, ... http://microscopecameraadapters.com/microscope-camera-adapters/making-microscope-camera-adapters/
