Microfilming, photography or filming using a microscope, providing the production of photographic images with magnification. Refers to a special type of photography. It is used in biology, medicine, geology, metallurgy and many other fields of science and technology as a means to study the microstructure of objects. For photomicrography using both optical and electron microscopes.
Optical microscopes allow for microphotography with up to 3500. The simplest micro-filming installation includes an optical microscope, an ordinary camera or camera and reticule device (visor). The actual optical image on the photosensitive emulsion layer is formed only lens or microscope, or the entire optical system of the microscope (objective + eyepiece), or (less commonly) an optical system and microscope imaging camera (lens + eyepiece + lens shooting).
Filming apparatus is connected to the microscope through light-tight detachable device (light castle) camera mounted on a movable platform, the edge can move (within limits) along the optical axis of the microscope objective. To eliminate the transmission of vibrations from operating the movie camera to the microscope they are placed on the massive, unrelated bed.
Photomicrography is often performed with the aid of special micro photo tips, mounted on a conventional optical microscope tube.
Large research microscopes have a built-in camera crews.
For micro - are filming a special micro filming setup.
Photomicrography using electron microscopes can obtain photographic images of microscopic objects with up to 10 times.
The image is projected on the photographic material, either directly or on the phosphor screen, from which the photo or filming.
Some crews set with electron microscopes equipped with video recorders and TV video monitoring unit.
If you use a variety of microfilming filters and special lighting techniques, allowing to significantly expand its capabilities.
Photographic materials for microfilming selected depending on the properties of the object, target shooting, and areas used by the optical radiation.
