Aven SPZH-135 Binocular Body Microscope - 21x-135x

Product Features: Ideal for wide range of investigative and inspection applications that require high magnification 15x (FN.20) eyepieces provide 21x to 135x continuous zoom High precision optics ensure excellent contrast and definition for 3D images Eyepieces set at 45 degree angle to provide comfortable viewing for all operators Adjustable interpupillary distance between eyepieces of 1.96 and 2.91 in. further ensures comfort for any user Graduations on zoom knob indicate exact magnifications, allowing for specific adjustments Optional auxiliary lenses and eyepieces extend magnification range from 14x to 180x The Aven Tools SPZH-135 Binocular Stereo Zoom Microscope is the ideal scope for a wide range of investigative and inspection applications. The SPZH-135 extends the boundaries of stereo zoom microscopy, employing standard 15X eyepieces to achieve 21x to 135x continuous zoom magnification, all the while providing a continuous working distance of 3.3 in. (84 mm). Graduations on the zoom knob indicate to operators the exact magnifications at which they are working; this is particularly helpful for applications requiring very specific adjustments. Replacing the standard 15X eyepieces with optional DHW20X eyepieces enhances the magnification range of this dynamic microscope from 28x to 180x. Having eyepieces set at a 45 degree angle, the adjustable interpupillary distance between eyepieces of 1.96 to 2.91 in. means they can be set to the comfort level of any user.
