Optical microscope MAGUS Bio 230BL
The MAGUS Bio 230BL microscope is ideal for examining biological samples as part of routine laboratory or research work. With it you can study translucent and transparent samples in transmitted LED light. The microscope has achromatic optics and a thoughtful design for adjustment to different observing conditions and for different users. A line of accessories has been developed for the microscope that allow you to increase the magnification range, obtain more magnifications within the range, and use dark field, polarized light and phase contrast methods for observations. Optical design The optics are built on the basis of achromat lenses with infinity correction. The package includes 4 lenses; a total of 5 lenses can be installed in the revolving device at the same time. The revolver is in the “from the observer” position, so the space above the table is free, and the user can clearly see the lens selected for work. The microscope is equipped with a binocular visual attachment. Diopter adjustment is performed on the left eyepiece tube; it can also be used to install a digital camera (purchased separately). The eyepiece tubes rotate 360° to adjust the height of the exit pupil to the height of the observer. The optics of the microscope are designed for infinity; in the basic configuration, observations are carried out at a magnification of 40 to 1000 times. With optional eyepieces, the upper magnification limit increases to 1500x, 1600x or 2000x. Lighting system A 3 W LED with a long operating life of about 50,000 hours is used to illuminate the work area. Changing the brightness of the light does not change its color temperature. Thanks to the presence of a field diaphragm, you can use the Köhler method when setting up lighting. And in a special condenser slot you can install sliders: dark field or phase contrast. The use of sliders speeds up switching between different research methods and makes working with the microscope more convenient. Mechanics The stage does not have a retractable rail, and the specimen guide can be removed during manual scanning. The sample moves across the table smoothly. At the bottom of the body there are coaxial coarse and fine focusing knobs. For coarse focusing, travel stiffness adjustment and locking are provided. The focusing mechanism is responsive and does not require any extra effort during adjustment. Accessories The line of accessories compatible with the MAGUS Bio 230BL microscope includes: dark-field condensers, eyepieces, objectives, devices for research in polarized light and using phase contrast, digital cameras, calibration slides.
