Carl Zeiss Microscopy LLCRequest Info
Carl Zeiss MicroImaging Inc. has introduced the Axio Lab.A1 microscope for use in polarization microscopy, student education and routine laboratory applications. This upright microscope suits colleges, universities and research institutes in the fields of geoscience and mineralogy, and in the oil exploration industry. It enables microscopic examinations of primarily thin geological and mineralogical specimens of glass and polymer samples. It features rapid, reliable switching from orthoscopy to conoscopy. The new stand for conoscopic examinations includes an integrated depolarizer and a rotary analyzer. The focusable Bertrand lens placed on the stand is linked to the analyzer, allowing operating convenience and error-free use. The system can be used with traditional and AxioCam line cameras, with AxioVision image processing software and with the AxioCam ERc 5s.

Bertrand lens
A small convergent lens, located between the objective and eyepiece of a microscope, that focuses an image of the upper focal plane of the objective in the focal plane of the eyepiece. It is commonly used with polarized light to examine the interference figure, and it is also used to quickly verify an aperture's centering, size and uniform illumination.
A device that obliterates the polarization of a polarized beam by reflecting the beam in all directions at right angles to its axis.
A noncrystalline, inorganic mixture of various metallic oxides fused by heating with glassifiers such as silica, or boric or phosphoric oxides. Common window or bottle glass is a mixture of soda, lime and sand, melted and cast, rolled or blown to shape. Most glasses are transparent in the visible spectrum and up to about 2.5 µm in the infrared, but some are opaque such as natural obsidian; these are, nevertheless, useful as mirror blanks. Traces of some elements such as cobalt, copper and...
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...
A material whose molecular structure consists of long chains made up by the repetition of many (usually thousands) of similar groups of atoms.
