Features

1.Click stop function

New main magnification freeze frame function has been added, which can accurately and repeatedly locate the same magnification, effectively solving the problem of magnification calculation when observing objects. The zoom handwheel feels lightweight and comfortable, effectively avoiding fatigue caused by long-term operation.

2.Flatness and depth of view

Greenough optical system with convergence angle of 10 degree, and working with wide field plan eyepieces, ensures the excellent flatness and depth of field.

3.Diverse auxiliary objectives

Various auxiliary objectives 0.3X/0.4X/0.5X/0.7X/1.5X/2X for option, to expand BS-3042T3 stereo microscopes’ magnification from 2X to 180X. The Max. working distance is 287mm while the Min. is 26mm, to meet all the requirements from different applications.

4.Abundant illumination systems.

LED/halogen/fluorescence illuminations for option, either built-in illuminator or external type is available, provide the best image by choosing a suitable light.
