ZEISS SteREO Discovery V8 Stereo Zoom Microscope
The ZEISS SteREO Discovery V8 is a common main objective stereo microscope with parfocalled Apochromatic optics over the entire magnification range from 1x-8x. Selectable click-stops allow calibration of pixel sizes when using the ZEISS imaging software package ZEN.
Viewing Head: Trinocular head with 20º inclined eyetubes. Interpupillary distance adjustment from 51mm - 75mm. Beam splitter takes 100% of light from the right eyetube to the photo port.
Detent: Manual focus drive with adjustable click stops.
Eyepieces: Includes widefield 10x / 23mm focusing eyepieces. Eyepieces accept 26mm diameter reticle. 16x/16mm eyepieces and 25x/10 are available and can be ordered below.
Objective Lens: Zoom range of 1x - 8x is provided with your choice of:
1x Achromat Objective (WD = 63mm)
1x Plan Achromat Objective (WD = 81mm)
1x Plan APO Objective (WD = 60mm)
Zoom Ratio: 8:1
Total Magnification: 10x - 80x. For alternate magnifications eyepieces can be changed and objective lens swapped out on the stereo microscope. View magnification chart below for options.
Stand: Track stand with transillumination base with 90 white-light LED transmitted light, brightness knob, and socket for footswitch. 3-position turret for brightfield plus oblique light contrast by shiftable diaphragm, homogenous brightfield with 67mm diameter, and all-side darkfield, also unilateral by movable diaphragm.
