Stereoscopic microscopes are used for viewing 3-dimensional objects, inspection or assembly of small
parts, and for dissection of biological specimen. They provide an upright, unreversed image which
permits easy manipulation of the object being viewed while looking through the microscope. They are
designed for viewing solid objects at low magnification, but they will also permit viewing of some
transparent specimen slides.
Carefully read this manual and familiarize yourself with the components and controls identified in the
diagram provided.
UNPACKING & ASSEMBLY
Do not touch any of the lens surfaces while handling the microscope. Dust, dirt, fingerprints can damage
the delicate lens surfaces or adversely affect image quality.
Remove microscope stand and head assembly from carton. Remove rubber eyeshields, dustcover and
warranty card. Remove "L hex wrench" (used to remove locking set screw on stage plates), and "pin
spanner wrench" (used to adjust focusing tension).
Microscope models having both incidental (top) and transmitted (bottom) illumination are supplied with a
frosted glass stage plate (80mm diameter) already mounted in the microscope base. They are also
supplied with an accessory black/white contrast plate packed in the styrofoam container. 405 Series
purchased after 1/1/10 will be supplied with contrast plates, one black and one white.
Models with no illumination, or top illumination only, are supplied only with a black/white plastic contrast
plate (60mm diameter) already mounted in the base of microscope.
Install rubber eyepiece shields over top of eyepieces with the flared portion of the shields positioned at
the outside edge of eyepieces.
Observe that the main voltage of your microscope is labeled on the back of the base. Make
certain that the main voltage of your microscope corresponds to the voltage of your power outlet.
Examine packing material before you discard it. Retain the styrofoam container in case you need to
transport, store, or return the microscope for service. If it becomes necessary to ship the microscope for
any reason, pack it in the styrofoam container, and then pack the styrofoam in another corrugated
shipping container for optimum protection.
Use of the styrofoam alone will not provide adequate
protection in transit, and will void your warranty.
OPERATION
The 400 and 405 series have the same features, function and procedures for operation. The only
difference is that the 400 series has a vertical viewing head (eyepieces are straight up and down) and the
405 series has a 45° inclined viewing head. The inclined viewing head permits more comfortable viewing
angle when user is seated.
Microscope magnification is determined by multiplying the number on the eyepiece times the number on
the objective lens. These numbers are incorporated in the model number of your particular microscope
purchase.
For example, 400TBL-10-2 has 10x eyepieces and 2x objectives, which provide 20x
magnification.
Model 400-10-2 (no illumination) is available only with the 2x objective option, and since the 2x objective
is fixed permanently in place, there is no 2x marking on the objective.
