Motic 1100100402251 BA310Pol Trinocular Head Polarization Microscope (Light Split = 20/80) Siedentopf Type 100-240V (CE)

Based on the success of its popular BA Microscope Series for biomedical applications, Motic is pleased to introduce the BA310POL, an extremely powerful yet affordable polarization microscope for transmitted light samples.

The BA310POL is designed for the examination of birefringent samples from petrography and mineralogy, and can also be used for the synthetic materials industry where repeatable observations can be performed with efficiency and reliability. The BA310POL also works especially well in educational applications of material professions, where affordability and ease-of-use are the key requirements.

The BA310POL is a powerful Polarization microscope for transparent specimen of diverse origin. Fully integrated in Motic's BA family of Upright microscopes, this microscope is especially meant for the examination of birefringent samples from petrography and mineralogy, but can also be used for synthetic materials like foils or fibers from industial production. The BA310POL also works well in Educational environments of material professions, where affordability and ease of use is a key issue. A reliable Polarization microscope has to fulfill unique demands dictated by the sample characteristics. Careful attention has to be paid on strain-free optical components as well as smooth rotation of the circular stage.

Following Motic's newest developments of lead-free manufacturing in full compliance with RoHS regulations, the strain-free versions of the new EC Plan Achromatic lenses naturally provide optimal image quality through a multi-layer lens coating. With crossed polarizer/analyzer, a dark image background is ensured. The pre-centered rotating stage has got a hard coated and chemical resistant surface, while a high precision ball-bearing mechanism ensures smooth rotation. The built-in 30W light source is part of a Full Koehler setup for optimized image contrast by reducing stray light. The Intermediate Tube, an integral part of the standard microscope package, carries a Bertrand lens, both focusable and centerable. As a standard, an anti-fungus treatment has been applied to the complete microscope to ensure a long lifetime of both microscope mechanics and optics in humid environments. 

Smooth movement and precise positioning

The BA310POL microscope stand carries a pre-centered stage with a hard coated surface to withstand abrasion even under rough usage. A high precision ball-bearing mechanism ensures a smooth rotation for a precise positioning of the sample. The fully rotatable polarizer is fixed to the sub-stage condenser carrier. The ball bearing 4-fold nosepiece shows a reversed orientation. In reference to a given objective position, all other objectives can be centered individually. All eyepiece tubes allow the mounting of the crosshair eyepiece both in orthogonal and diagonal cross position. Incorporating an interpupillary distance of 55-75mm, the BA310POL observation tubes guarantee hours of fatigue-free viewing. Digital documentation through the photo port of both trinocular tubes is possible, with 20/80 or 0/100 light split option.

EC plan achromats and conoscopic tools

For the specific demands of the BA310POL microscope, Motic introduced a set of strain-free EC Plan Achromatic objectives. Following the CCIS® concept, these objectives are made of high quality glass with multi-layer coating for better contrast. The tube lens provides a completely corrected intermediate image with photo port for high quality documentation. Further objectives from Motic's BA series may also be used, keeping the minimized degree of extinction in mind. The standard high eyepoint eyepieces N-WF 10X/20mm provide consistent diopter adjustment for both eyes. As required for polarization work, one eyepiece is equipped with a fixed crosshair reticle. As an integral part of the BA310POL packages, the Intermediate tube carries a Bertrand lens, both focusable and centerable, and additionally the analyzer, thus revealing conoscopic information of crystal substructures. Moreover, a built-in slot allows the use of optional retardation and compensator sliders. The first order (also known as full wave or λ plate) retardation plate certainly will be most interesting, while the use of Quarter-wave retardation plate (1/4 λ) and Quartz wedge compensator plate are less common.

Flexible illumination

The Transmitted illumination is based on a 30W Halogen light source. With an adjustable field diaphragm and aperture diaphragm, Full Koehler quality is given in terms of a homogenous illumination and reduced stray light. The Achromatic Swing-out condenser with N.A. 0.90/0.13 is strain-free and contributes to a darkest possible image background.
