1.4 General use of stereomicroscopes
The stereomicroscopes Stemi DV4 / DR are Greenough-type microscopes mainly designed for versatile
hobby and training applications and for routine work in biology, medicine and industry.
The name DV4 stands for Double Lens Vario with the zoom factor 4. The zoom range of 4:1 corresponds
to the overall magnification range of 8x to 32x (basic version).
The zoom magnification changer guarantees high-contrast, sharp images over the entire zoom range.
After the basic setting of the stereomicroscope, the image remains exactly in focus.
The name DR stands for Double Lens Revolver and means that these stereomicroscopes use two fixed
magnifications which can be switched discretely. Stemi DR 1040 with overall magnifications 10x and
40x, Stemi DR 1663 with 16x and 63x (basic configuration).
Their compact design makes the stereomicroscopes Stemi DV4 / DR ready for immediate use and very
easy to operate. Depending on requirements, these microscopes can be converted and upgraded in
accordance with the modular system of Zeiss stereomicroscopes.
Interchangeable optics components permit the magnification range to be varied as required.
Modern illumination equipment for reflected and transmitted light is integrated in stand C. As a standard
feature, the press of a key is sufficient for the selection of:
−
brightfield illumination in reflected light
−
brightfield illumination in transmitted light
−
brightfield illumination in mixed light
And optional:
−
darkfield illumination in transmitted light
The illumination intensity can be set continuously and electronically at the press of a button for each
illumination type and can therefore be matched to most different objects.
Suitable eyepiece adapters are available for image documentation using:
−
the SONY cameras "Digital Handycam DCR-PC100", "Digital Still Camera Cybershot DSC-F505" and
"Digital Still Camera Cybershot DSC- S70"
−
35 mm SLR cameras
−
still/video and video cameras with C-mount connector
−
video cameras for insertion in the eyepiece, e.g. from L.O.T.-Oriel GmbH; SCI-EYE, Inc.
−
microhead video cameras (head diameter: 17 mm) in the JAI-M2200 series

The adaptation of other digital cameras with M37 or M52 objective / filter thread must be
tested, as described in section 3.2.3.2, page 3-12!
