1, OUTLINE OF MERCHANDISE
AHBS3
This is the automatic type PHOTOMICROGRAPHICAH3 body for biology
designed for use in laboratories, which is remodeled from AH2 (AHBS)
by widening the auto focus range.
AHBT3
This is the manual type PHOTOMICROGRAPHICAH3 body for biology
designed for use in laboratories, which is remodeled from AH2 (AHBT)
by making the CONDENSERTURRET automatically interlocking with
the objective magnification.
AHMT3
This is the UPRIGHT TYPE PHOTOMICROGRAPHICAH3 body for metallurgy
designed for use in laboratories, which is remodeled from AH2 (AHMT)
by increasing the stage vertical mountable range 18mm to permit
observation of a thick specimen.
2, FEATURES
AHBS3
(1) Built-in photographing unit of the AVERAGE/SPOTMETERING
selectable type
(2)
Attachable with three cameras and one TV camera at same time
(3) Auto focusing from low to middle magnification (objective 1X - 40X)
(Auto focus features called AF)
(4j Scale and data imprintable and photographing in half size
(5) Single lens REFLEX FINDER
(6) Motorized REVOLVINGNOSEPIECE
(7) Illumination systems such as condenser, field diaphragm, aperture
diaphragm are all adjusted automatically, linked to each objective
magnification.
(8) Full KOHLERILLUMINATION
(9) Super wide field of view (FIELD NUMBER26.5)
(10) Four built-in photographic eyepieces (2.5X, 3.3X, 4x, 5x)
(11) Built-in light balancing filter, ND filter and contrast filter
(12) 'Gu‘henthe built-in lamp switch is turned off in observation of
reflected light fluorescence (using AH3-PFCA), the condenser, AS
and ND are not moved even if an objective is changed.
(This is the feature for the user who use the reflected light
fluorescence only and does not use the transmitted light.)
(13) This model (A2-AAC-2) has improvement against protection of self
fluorescence light of A2-AAC in observation with the reflected
light fluorescence

* At the position@, if the Nomarski prism is attached, it interferes

specimen can be observed, and the position@is unnecessary in
SICG.)
* At the position@ when the stage is moved toward the depth
direction, it interferes with the main body dovetail and the
stage stroke is decreased.
(13) If the stage is set at lower position for observing a thick
specimen, the stage rotation angle is decreased. (At combination
of SVR and SVL) (The decreasing level differs for X and Y positions
of the stage. The rotation angle in the worst condition is about 300.)
(14) If the stage is set lower, the stage handle is close to the base
affecting maneuverability. (At combination of SVR and SVL)
(15) When the halogen lamp other than the specified one is used, the
following conditions are added. (Same as AH2)
@ The lamp optical axis may not be cantered.
@ The lamp life time is not ensured.

AHMT3
(1) use the OBJECTIVE and EYEPIECE of the LB series.

can not be used.
(3) Allowable supply voltage fluctuation

(4) Operating temperature: 0 - 40°C
(5) Wait at least 3 seconds when turning on after it was turned
Off.
(6) Transmitted light observation is possible only when AH2-LWCD
attached to AH2-SIC6. In the standard combination of AH2-SVR
and SVL, the LONGWORKINGDISTANCE CONDENSER(AH2-LWCD) can not
be attached and the transmitted light observation is impossible.
(7) When setting stage to location other than three screw locations,
ncted below, fix stage securely to the dovetail of the main body.
(8)
The uppermost screw position (0) can not be
(See the drawing below.) used in with AH2-SIC6.
(9) As the specimen load is increased, traceability becomes worse
and the stage bending amount is increased. (S&e level as the
structure is the same as AH-2)
(10) W:-.en the guide dovetail becomes llrrun or less from the top in the
transmitted light illumination, the luminous flux is blurred.
This is no problem in practical use. (Same level as AH-2)
(11) A turret condenser (A2-TCS, A2-TCT, A2-TCS2, A2-TCT2) can not
be attached.
(12)
Ii the stage is set lower than the middle screw position (0)
(-&hen observing a thick specimen), the stage stroke of Y axis
is decreased.

Condenser is switched automatically according to the objective
magnification. Applicable revolving nosepieces are ~2-6RE2
(A2-BTL) and AH3-RFCA. When the condenser is manually switched,
the objective does not moved with it.
When the built-in lamp switch is turned off in observation with
reflected light fluorescence (using AH3-RFCA), the condenser is
not switched even if an objective is changed. (This is the
feature for the user who use the reflected light fluorescence
only and does not use the transmitted light.)
The data setting position of the objective and condenser is
stored even if the main switch is turned off.
