BRESSER

Harness the power of contrast-enhancing polarization microscopy and conoscopy using the Bresser Science MPO 401 Microscope. This fine instrument incorporates polarization and conoscopy techniques to generate brilliant images of crystalline and anisotropic structures. To achieve this, the optical configuration gives you a set of four polarization-optimized (low-strain) plan achromatic DIN objectives, a bottom (transmitted) 20W halogen Kohler illumination, a polarizer/analyzer assembly (for polarization studies), an in-and-out Bertrand lens (for conoscopy), and a 360 rotating stage.An integral part of the illumination system are an Abbe condenser with an in-and-out auxiliary lens, an iris diaphragm, a polarizer, and a filter holder. The entire condenser assembly has a height adjustment, while the auxiliary condenser lens can be centered to regain alignment by way of external screws. To meet the requirements of polarization microscopy, the round metal stage rotates 360 and has a degree scale along the circumference that permits accurate positioning and achieving a proper orientation of a sample. It can be raised or lowered with the height-adjustment knob and centered via centering screws to ensure an on-axis rotation of your sample. For implementation of polarized light microscopy, the head contains a swinging in-and-out analyzer with graduations, and for conoscopy, it has a removable Bertrand lens and a slot for phase components like phase retarders, wave plates, and wedges.Other highlights of this tool are its coarse and fine focusing with 2 m minimum increments, a tension ring, and a stop knob. In order to take photos or videos of your discoveries, you will need to connect a camera to a third optical tube and switch from a viewing mode to a photo mode. Should you decide to upgrade this microscope to conduct phase contrast studies as well, it can be achieved with the optional Bresser Phase Contrast Set 5942750.Optical Design For polarization microscopy and conoscopy Convertible to a phase contrast microscope with the optional Bresser Phase Contrast Set 5942750 Polarizer and analyzer for polarization studies Center-adjustable in-and-out Bertrand lens for conoscopy DIN, plan achromatic 4x, 10x, 40x, and 100x objectives are optimized for polarization microscopy (low strain) 40x and 100x objectives are retractable 100x objective requires immersion oil Two widefield 10x eyepieces with 23.5mm tube diameters Phase shifter for generating phase differenceTransmitted Kohler Illumination 20W halogen lamp with adjustable brightness 360 rotating polarizer for polarization microscopy Height- and center-adjustable Abbe condenser Auxiliary condenser lens can swing in and out Iris diaphragm with variable aperture Bottom filter holderUse and Handling 30 inclined viewing Head rotates 360 Siedentopf interpupillary adjustment: 52.5-75mm Coarse and fine focusing Focus tension ring and stop knob Selectable viewing or photo modes Diopter adjustmentRound Rotating Stage Center adjustable 360 rotation Degree ruler along perimeter Two metal slide clipsConstruction Details Durable metal and plastic frame Wide stable base with rubber feet Ball-bearing nosepiece Knurled adjustment rings and levers
