Example Configurations for Materials Science and Industry
There are two types of microscope frames in the BX3M series, one for reflected light only and one for both reflected and transmitted light. Both frames can be configured with manual, coded, or motorized components. The frames are outfitted with ESD capability to protect electronic samples.
IR objectives can be used for semiconductor inspection, measurement, and processing applications where imaging through silicon is required to see the pattern. 5X to 100X infrared (IR) objectives are available with chromatic aberration correction from visible light wavelengths through the near infrared. For highmagnification work, rotating the correction collar of the LCPLNIR series of lenses corrects for aberrations caused by sample thickness. A clear image is obtained with a single objective.
The optics of the BX53M polarized light combination provide geologists with the right tools for high-contrast polarized light imaging. Applications such as mineral identification, investigating the optical characteristics of crystals, and observing solid rock sections benefit from system stability and precise optical alignment.
Bertrand Lens for conoscopic and orthoscopic observations

With a U-CPA conoscopic observation attachment, switching between orthoscopic and conoscopic observation is simple and fast. It is focusable for clear back focal plane interference patterns. The Bertrand field stop makes it possible to obtain consistently sharp and clear conoscopic images.
An Extensive Range of Compensator and Wave Plates
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, the Berek and Senarmont compensators can be used, which change the retardation level in the entire field of view.
Measuring range of compensators
*R = retardation level
For more accurate measurement, it is recommended that compensators (except U-CWE2) be used together with the interference filter 45-IF546.
Strain Free Optics
Thanks to Olympus’ sophisticated design and manufacturing technology, the UPLFLN-P strainfree objectives reduce internal strain to the minimum. This means a higher EF value, resulting in excellent image contrast.
The BXFM can be adapted to special applications or integrated into other instruments. The modular construction provides for straightforward adaptation to unique environments and configurations with a variety of special small illuminators and fixturing mounts.
Modular Design, Build Your System Your Way
Microscope Frames

There are two microscope frames for reflected light, one also has transmitted Light; capability. An adapter is available to raise the illuminator to accommodate taller samples.
Stands

For microscopy applications where the sample will not fit on a stage, the illuminator and optics can be mounted to a larger stand or to another piece of equipment.
