{"product_id":"microscopio-biologico-magus-bio-250b","title":"MAGUS Bio 250B Biological Microscope","description":"\u003cp\u003eThe MAGUS Bio 250B biological microscope is an optical instrument used to study thin transparent and translucent objects. Transmitted light brightfield microscopy is the main microscopy technique used in this instrument. The microscope can be equipped with additional accessories for darkfield, phase contrast, and polarization techniques. High-quality optics coupled with additional options to expand its performance, user-friendly mechanical elements, and a smart design make this microscope an excellent choice for lab work, research, and teaching.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eOptics\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe binocular head allows for a digital camera to be installed in one of the eyepiece tubes (camera not included). The tubes can be rotated 360° to achieve a comfortable position that suits the observer's height. The diopter adjustment ring is located on the left tube.\u003c\/p\u003e\u003cp\u003eThe revolving nosepiece allows for 5 objectives to be installed. The microscope comes with infinity-corrected plan achromatic objectives that provide clear, high-contrast images across the entire field of view. There is a free position in the revolving nosepiece to install an additional objective. The revolving nosepiece with objectives is inward-facing: the user can see the objectives inserted into the optical path, and the space above the stage is clear.\u003c\/p\u003e\u003cp\u003eIn its basic configuration, the microscope's optics provide a magnification of 40 to 1000x. If necessary, additional eyepieces can be used to increase the upper limit of the magnification range.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIllumination\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eLight source: 30W halogen bulb. It provides uniform, bright illumination of the sample under any objective and observation method used, including darkfield and phase contrast techniques. The illumination is warm, which is comfortable for the eyes, so they will not get tired even when working with the microscope for long periods of time.\u003c\/p\u003e\u003cp\u003eThe Abbe condenser has a slot for inserting a darkfield slider or a phase slider. The condenser's design allows for easier and faster switching between research techniques. The condenser is height-adjustable and can be centered. The field diaphragm allows for setting up the Köhler illumination system.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eStage and focusing mechanism\u003c\/strong\u003e \u003c\/p\u003e\u003cp\u003eThe stage is equipped with a mechanical micrometre, which can be removed for manual scanning. There is no positioning rack, which ensures ergonomic operation of the stage.\u003c\/p\u003e\u003cp\u003eFocus adjustment is done using the coaxial coarse and fine focus knobs, located on both sides of the microscope body. The focusing mechanism is smooth and precise, and no effort is required to turn the knobs. The coarse focusing mechanism has a locking knob and a tension adjustment knob. The focus knobs are located at the bottom. Therefore, the user can rest their hands on the table instead of holding their arms in the air. This increases comfort during long working sessions.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eAccessories\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eA wide range of accessories allows the MAGUS Bio 250B to be configured in the most suitable way for the user.
