Polarizing Microscope BX51-P : Features (2)
- Enhanced operational ease and outstanding optical performance
- Special Features
An upgrade in polarization characteristics.
Thanks to Olympus' sophisticated design and manufacturing technology,
new ACH-P and UPLFL-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 contrast.
To meet a diversity of research and application requirements, the universal
UPLFL-P Series objectives have been designed to accommodate a wide range
of observation methods, including Nomarski DIC and fluorescence microscopy,
in addition to polarized light observation.
* The EF (extinction factor) is the brightness ratio between parallel and
crossed pol-filters. The higher the EF value, the better the extinction.

An extensive range of compensators is available.
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.
Measuring range of compensators
| Compensator | Measurement range | Applications |
|---|---|---|
| Thick Berek (U-CTB) | 0-11,000nm (20λ) | Measurement of high retardation level (R*>3λ), (crystals, macromolecules, fiber, etc.) |
| Berek (U-CBE) | 0-1,640nm (3λ) | Measurement of retardation level (crystals, macromolecules, living organisms, etc.) |
| Senarmont compensator (U-CSE) | 0-546nm (1λ) | Measurement of retardation level (crystals, living organisms,
etc.) Enhancement of image contrast (living organisms, etc.) |
| Brace-Koehler compensator 1/10λ (U-CBR1) | 0-55nm (1/10λ) | Measurement of low retardation level (living
organisms, etc.) Enhancement of image contrast (living organisms, etc.) |
| Brace-Koehler compensator 1/30λ (U-CBE2) | 0-20nm (1/30λ) | |
| Quartz wedge (U-CWE) | 500-2,200nm (4λ) | Approximate measurement of retardation level (crystal, macromolecules, etc.) |
*R= retardation level
For more accurate measurement, it is recommended that compensators
(expect U-CWE) be used together with the interference filter
45IF546.
Unmatched sharpness in orthoscopic and conoscopic observations.
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.
