The Olympus BX53-P polarizing microscope provides superb performance in polarized light applications using a combination of UIS2 infinity-corrected optics and a distinctive optical design. An extended line of compatible compensators make the BX53-P microscope versatile enough to handle observation and measuring applications in virtually any field.

Six different compensators are available for measurements of birefringence in rock and mineral thin sections. Measurement retardation level ranges from 0 to 20λ. For easier measurement and high image contrast, Berek and Senarmont compensators can be used, which change the retardation level in the entire field of view.

With a conoscopic observation attachment, switching between orthoscopic and conoscopic observation is simple. It is focusable for viewing of clear back focal plane interference patterns. The Bertrand lens is focusable for clear viewing back focal plane interference patterns. The  field stop makes it possible to consistently obtain sharp conoscopic images.

The rotating-centering mechanism attached to the rotary stage  enables smooth rotation of a specimen. In addition, there is a click-stop mechanism at each 45 degrees for precise measurement. With the optional dual-mechanical stage, discreet X-Y movement is possible.

Maximizing the advantages of infinity correction, the UIS2 optical system helps prevent the deterioration of optical microscope performance and eliminates magnification factors, even when polarizing elements, like analyzers, tint plates, or compensators, are introduced into the light path. The BX53-P microscope also accepts intermediate attachments available for BX3 series microscopes, as well as cameras and imaging systems.

A technical but important element of photography is depth of focus, which is easily confused with depth of field. Sometimes called “lens-to-film tolerance,” depth of focus has to do with the distance between the camera lens and the film plane or camera sensor.
