  • Hitachi High-Technologies Canada

Jul 2010
Hitachi High-Technologies Canada has selected Olympus Canada Inc. to be the exclusive distributor of its TM3000 tabletop scanning electron microscope in Canada. The fully automated instrument can achieve 30,000x magnification and good depth of field, making it a suitable complement to Olympus’ range of optical microscopes and digital cameras. Its applications include nano- and biotechnology, life sciences, pharmaceuticals and education.

A light-tight box that receives light from an object or scene and focuses it to form an image on a light-sensitive material or a detector. The camera generally contains a lens of variable aperture and a shutter of variable speed to precisely control the exposure. In an electronic imaging system, the camera does not use chemical means to store the image, but takes advantage of the sensitivity of various detectors to different bands of the electromagnetic spectrum. These sensors are transducers...
depth of field
The distance, on either side of the object plane focused on, through which satisfactory image definition can be obtained. For the special case of an imaging system with lens axis perpindicular to the image plane, focused at a range of 25 ft, and with definition acceptable for objects from 20 to 40 ft; the depth of field extends from 5 feet in front of, to 15 feet behind, the object plane focused on.
digital camera
A camera that converts a collected image into pixels that are black or white digital or shades of gray. The digital data may then be manipulated to enhance or otherwise modify the resulting viewed image.
The ratio of the size of the image of an object to that of the object. The ratio of the linear size of the image to that of the object is lateral magnification. Angular magnification is the ratio of the apparent angular size of the image observed through an optical device to that of the object viewed by the unaided eye. Longitudinal magnification is the ratio of the longitudinal or axial dimension of an image to the corresponding dimension of the object.
An instrument consisting essentially of a tube 160 mm long, with an objective lens at the distant end and an eyepiece at the near end. The objective forms a real aerial image of the object in the focal plane of the eyepiece where it is observed by the eye. The overall magnifying power is equal to the linear magnification of the objective multiplied by the magnifying power of the eyepiece. The eyepiece can be replaced by a film to photograph the primary image, or a positive or negative relay...
The use of atoms, molecules and molecular-scale structures to enhance existing technology and develop new materials and devices. The goal of this technology is to manipulate atomic and molecular particles to create devices that are thousands of times smaller and faster than those of the current microtechnologies.
