- Phone Microscope Accessory Developed
A pocket-size accessory that turns an ordinary camera phone into a high-resolution microscope can accurately obtain images with resolution of 0.01 mm. Scientists at VTT Technical Research Centre of Espoo, Finland, have developed a microscope that attaches to a mobile camera lens with a magnet. It can examine various surfaces and structures in microscopic detail and can take high-resolution images that can be forwarded as MMS (Multimedia Messaging Service). It has applications in the security, health care and printing industries. VTT and KeepLoop Oy of Tampere, Finland, are exploring the commercial potential of the device. The first industrial applications and consumer models were expected to be released in early March 2012.
- A transparent optical component consisting of one or more pieces of optical glass with surfaces so curved (usually spherical) that they serve to converge or diverge the transmitted rays from an object, thus forming a real or virtual image of that 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...
