With fixed inclination angles of 45 and 60 degrees, the SMZ445 and SMZ460 stereo microscopes feature lightweight porro prism optics and have ESD protection to prevent electrostatic damage to samples. In standard format, the SMZ445 offers a total magnification range of 8× to 35× and has a working distance of 100 mm. This can be extended to 4× to 70× by changing the eyepieces and selecting an auxiliary objective. Comparable figures for the SMZ460 are 7× to 30×, extendable to 3.5× to 60×. Compact yet robust, both models With the addition of these two models, the user can harness the quality of proprietary ultra-high performance optics for application requiring anything from a 4.3:1 up to a 15:1 zoom ratio.
