An excellent routine and educational grade polarising microscope featuring a trinocular head with a photoport for a camera and 40X to 600X magnification range. For the eye pieces, a pair 10X eyepieces with a crosshair are featured as well as , 4 plan achromatic, strain-free, centerable objectives 4X, 10X, 40X and 60X, giving you the 40X to 600X range. A 360° rotatable stage is present, as expected but also featured on this model are research level 1/4 & 1 wavelength retardation plates which helps the user with assessment of optical path differences in birefringent specimens. A bertrand lens is also installed, which allows the device to align the various optical components. Also included as standard are a retractable analyser in the head and rotatable polarisers. The transmitted light source is emitted via a 6 volt, 20 watt halogen light with a coarse and fine focus adjuster and a limit stopper. A highly robust construction will ensure knocks to the device will not faulter its accuracy, in all, it is an excellent microscope with a range of capabilities, ideal for use in education and research sectors, particularly for the observation of geological thin sections.
