Polarization Microscope

BioPhotonics
Nov 2010
Carl Zeiss Microscopy LLCRequest Info
 
Carl Zeiss MicroImaging Inc. has introduced its Axio Lab.A1 microscope for use in polarization microscopy, student education and routine laboratory applications. The upright instrument suits colleges, universities and research institutes. 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. It can be used with traditional cameras, cameras in the AxioCam line, AxioVision image processing software and with the AxioCam ERc 5s.

GLOSSARY
analyzer
An optical device, such as a Nicol prism, capable of producing plane-polarized light, and used for detecting the effect of the object on plane-polarized light produced by the polarizer.
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.
depolarizer
A device that obliterates the polarization of a polarized beam by reflecting the beam in all directions at right angles to its axis.
microscope
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...
