Optical microscope MAGUS Bio 250BL
MAGUS Bio 250BL is a microscope designed for studying biological samples in transmitted light. Planachromatic optics transmits a clear image with a minimum of distortion, a transmitted light LED provides uniform illumination without changing color temperature, and the ability to install additional accessories makes the microscope more flexible in customization to solve different problems. The microscope is perfect for laboratory and research work or teaching. Optical design The microscope is equipped with a binocular head with 360° rotating tubes. This design helps to quickly and effortlessly adapt the eye relief height to the height of the observer. To compensate for the difference in visual acuity between the eyes, there is a diopter adjustment ring on the left eyepiece tube. The digital camera is installed in place of the standard eyepiece (the camera is not included in the basic package). Since the revolving device is turned “away from the observer”, the working lens is clearly visible during operation, and the space above the table is free. It is possible to install 5 lenses at once: since 4 lenses are included in the kit, there is a slot for one additional one. All lenses compatible with this model are plan achromatic lenses designed for infinity. They provide the clearest possible image across the entire field of view. The optics provide zoom in the range from 40 to 1000 times. If additional eyepieces are used, the upper limit can be increased. Lighting system A 3-watt LED whose brightness is adjustable is used to illuminate the samples. When brightness changes, there is no change in color temperature, which ensures constant lighting conditions. The backlight is powered from the mains. The LED lifespan is 50,000 hours. Adjustment of the position of the Abbe condenser is possible both horizontally (centering) and vertically (change in height). In addition to the aperture diaphragm, the design also includes a field diaphragm. All together allows you to use the Köhler method to obtain a brighter and more informative image of the field of view. Another feature of the lighting system is the ability to use sliders. They are installed in a separate condenser slot and allow you to quickly change the research method. You can use a phase or dark-field slider. Mechanics Since the stage does not have a sliding rail, it provides greater comfort when working with the sample. It is also convenient that the drug guide used to move the drug can be removed - this is useful when scanning manually. Focusing is accomplished by rotating the coaxial focusing knobs. Both coarse and fine adjustments are available. The rigidity adjustment mechanism makes the coarse focusing stroke more responsive and comfortable, and there is also a coarse focusing stroke blocker. The design of the focusing mechanism is well thought out to improve ergonomics: the handles are coaxial and located on both sides of the body. There is no need to hold your hands up when adjusting the sharpness, since the handles are located at the bottom of the microscope. Accessories The wide range of accessories designed specifically for use with the MAGUS Bio 250BL microscope includes: objectives, eyepieces, calibration slides, digital cameras, as well as devices for dark-field observations using phase contrast and polarized light.
