21x to 135x magnification makes this system ideal for high magnification applications

The ideal scope for a wide range of investigative/inspection applications, Aven’s dynamic new microscope 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” (84mm). Replacing the standard 15X eyepieces with our DHW20X eyepieces enhances the magnification range of this dynamic new microscope further – 28X to 180X. Having eyepieces set at a 45 degree angle, the adjustable interpupillary distance between eyepieces of 1.96” (50mm) to 2.91” (74mm) means they can be set to the comfort level of any user.


  • Total Magnification of 21X to 135X at 3.3” (84mm) working distance, Max 180X with 20X eyepieces
  • Click stop zoom adjustments for accurate, repeatable measurement
  • Standard High Eye Point wide field 15x eyepieces at 45 degrees for comfortable viewing even for operators with eyeglasses
