The BX51P polarizing microscope is an investigative tool for the identification of isotropic and anisotropic materials, forensic analysis, thin film/polymer/crystal identification, and extraneous particulates
Thanks to Olympus' sophisticated design and manufacturing technology, new ACHN-P and UPLFLN-P strain-free objectives reduce internal strain to an absolute minimum. Olympus has also totally redesigned its polarizers and polarizing condensers to further enhance performance in polarized light. This means a higher EF* value, resulting in unmatched image brightness and contrast.
*EF value: the ratio of brightness of parallel Nicols to orthogonal(Cross) Nicols. The higher is the EF value, the less is the strain of the optical system. This means that a higher EF value is superior in polarization characteristics.

Observations can be performed comfortably and efficiently thanks to the Y-shape frame developed in pursuit of ultimate ergonomics. This greatly lessens operator's fatigue during the extended observation.
The Field Number is as large as 22, allowing a 21% wider area than that given by a microscope of ordinary filed number 20 to be observed at a glance. In addition, a bright halogen lamp of 12V-100W is used in the illumination system allowing observation of clear images of polarization.
The rotating-centering mechanism attached to the rotary stage allows smooth rotation of a specimen. In addition, there is a click-stop mechanism provided at each 45 degrees for precise measurement. With the option of adding a dual-mechanical stage further discreet x-y movement is possible.
|Six different compensators are available for the BX51-P microscope, allowing measurement of various retardation levels, ranging from 0 to 20λ. For easier measurement, the direct readout method is featured. Higher image contrast can be attained by using a Senarmont or Brace- Koehler compensator to change the retardation level in the entire field of view.|
|Retardation Measuring range of compensators|
|Compensator||Measuring Range||Major Application|
|U-CTB Thick Berek||0-11,000nm||Large Retardation Measurement (R*>3λ), ( Crystal , Giant Molecule, Fiber, Photoelastic Strain, etc.)|
|U-CBE Berek||0-1,640nm||Retardation Measurement ( Crystal , Giant Molecule, Fiber, Body Tissue, etc.)|
Retardation Measurement ( Crystal , Body Tissue, etc.)
Contrast Intensification (Body Tissue, etc.)
|U-CBR1 Brace-Kohler 1/10λ||0-55nm||
Minute Retardation Measurement ( Crystal , Body Tissue, etc.)
Contrast Intensification (Body Tissue, etc.)
|U-CBR2 Brace-Kohler 1/30λ||0-20nm|
|U-CWE2 Quarts Wedge||500-2,200nm||Preliminary Survey of Retardation ( Crystal , Giant Molecule, etc.)|
* R stands for retardation.
The use of an interference filter 45IF546 together is recommended for improving measuring accuracy (Except for U-CWE2).
Conoscopic Orthoscope Observation Units
With a U-CPA conoscopic observation attachment, changeover between orthoscopic and conoscopic observation is simple and quick.
Focusing of conoscopic images is easy and accurate. Employing a Bertrand field stop makes it possible to obtain consistently sharp and clear conoscopic images
