M300
Stereo Microscope has a three-step magnification changer (total maginfication 6.4x, 16x and 40x if 10x eyepiece and a standard 1.0x objective are used). (Optical Data)
M400
Stereo Microscope has a four-step magnification changer (total maginfication 6x, 12x, 25x and 50x if 10x eyepiece and a standard 1.0x objective are used). The microscope has an extremely narrow image angle, thus giving this stereo the greatest depth of focus of all Unitron models. (Optical Data)
M500
Stereo Microscope has a five-step magnification changer (total maginfication 6.4x, 10x, 16x, 25x and 40x if 10x eyepiece and a standard 1.0x objective are used). (Optical Data)
M700Z Zoom Magnification Microscope
Zoom stereo microscope has a stepless magnification changer with a 1:5.2 range (total magnification from 6x to 31x if 10x eyepiece and a standard 1.0 objective are used.) (Optical Data)
DUAL DISCUSSION MICROSCOPE (Dual (both) Step and Zoom Magnification Microscope)
Dual Discussion Head uses either step magnification changer microscope (M300 or M500) or the zoom microscope (M700Z). Two observers simultaneously see the same erect and laterally-correct image. Dual observation helps in the training of new staff and makes discussion eaiser
. (Optical Data)
