The included 10x eyepieces provide 10x to 44x continuous zoom, while high precision optics ensure excellent contrast and definition for 3D images from edge to edge. The magnification range may be extended to 140.8x with optional auxiliary lenses and eyepieces. A wide variety of lenses, stands and illumination is available to provide you with a microscope system to meet your individual requirements.
