Model 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.

• Head Siedentopf type 30° inclined [trinocular: (light split = ²⁰/₈₀)]
• Widefield high eyepoint eyepiece N-WF PL10X/20 mm with diopter
• Adjustment on both eyepieces, cross hair on one eyepiece
• Intermediate tube with rotatable analyzer and Bertrand lens
• Reversed quadruple nosepiece
• 360º circular rotating stage

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 30 W 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.
