The Sigeta MB-203 40x-1600x Professional Binocular Microscope - a premium instrument producing clear, sharp and detailed images with minimal optical distortion. The microscope is equipped with a binocular head with 360° rotation and an interpupillary distance adjustment in the range 54 - 75 mm. The right and left eyepieces have built-in dioptre correction to compensate vision differences of the eyes. The nosepiece lens holder has four mounting positions and has a rubber radial overlay for easy lens rotation and changing. The kit includes 4 achromatic lenses (4x, 10x, 40x, 100x) and two pairs of wide-angle glasses (10x, 16x) with anti-reflective coating.
The objective table (14 x 15.5 cm) is equipped with a specimen holder with coaxial handle and gear rails to move the holder. Beneath the stage a 1.25 Abbe condenser is housed together with a petal diaphragm regulating the image contrast. An LED lamp with a cool colour temperature is located inside the housing and is complemented by a removable lens assembly (Ø 43mm) with a matte coating. A mirror is also supplied to reflect and direct the light onto the specimen slide, which can be mounted in place of the main illumination module, giving this microscope autonomy and portability of use.
Another feature of this model is the focus adjustment located in the coaxial macro and micro screw handles assembly: the ring on the left side of the body controls the rotation power of the coarse focus handle, while the one on the right adjusts the maximum allowable elevation of the objective stage. This is helpful for laboratory work with constantly changing micro slides, as it prevents the possibility of damaging the specimen glass.
This laboratory instrument will open up new possibilities for detailed examination of micro-objects in histology, cytology, bacteriology and other fields of science.
