Optical microscope BA310 POL (20:80 option)

laboratoryuprightpolarizing

An advanced trinocular Polarization microscope for birefringent samples from mineralogy and petrography, but also for synthetic materials like fibres and foils. The Intermediate tube with Bertrand lens and compensator slot carries a 360° Analyzer. Users benefit from the Full-Köhler illumination with Field diaphragm, ready to work out a maximum image contrast.
