Abbé Condenser 1.25 N.A. (included on models T-19031C &
T-19041C)
The purpose of the condenser lens is to focus the light onto the specimen.
(adjust the amount of light needed on a specimen) The N.A. of 1.25 gives an
Abbé condenser the ability to be used with higher magnification 100x
objective lens. Movement of the condenser is controlled by a knurled knob
beneath the stage on the left side.
Mechanical Stage (included on models T-19031C & T-19041C;
Optional on T-19011C & T-19021C)
The mechanical stage is a mechanical way to move the slide around on your
stage. It consists of a spring loaded slide holder and two low position knobs on
the lower right side. One knob moves the slide forward and backward (y axis),
while the other knob moves the slide from left to right (x axis). The Vernier on
the x and y axis allow the user to precisely mark a location of something on a
slide that they may choose to return to at a later time.
Interchangeable Heads
Using an Allen wrench, insert into screw slot in arm next to head. Loosen screw
to remove plastic dust cap. Set desired microscope head on arm. Tighten
screw with Allen wrench until snug. No need to over tighten.
Adding a new Objective
Various objectives may be purchased for the Comprehensive 2 microscope as
options. Being careful to align the threads, simply screw the new objective into
one of the four slots in the head. DO NOT OVERTIGHTEN (In the T-19011C
and T-19021C as shipped standard, there is an empty fourth slot which may
be used). If unit already has four objectives in place, then one will have to be
unscrewed and new one inserted.
