Objectives:
Eyepiece:
10x
• Numerical aperture of condenser: 1.25.
• Moving range of mechanical stage: 50 mm x 75 mm.
• Minimum division of fine focusing scale: 0.002 mm.
• Adjustment range of interpupillary distance: 53 mm – 75 mm.
• Incident light source for fluorescence: 100 W super-high pres-
sure mercury lamp with DC power supply (AC 230 V / 50 Hz).
III. INSTALLATION
Remove all parts from their packing materials and retain the pak-
kaging in the event you need to transport the product. Install
all the units according to Fig. 3.
IV. OBSERVING OPERATION
1. Transmission-type bright field microscopy (Fig. 1)
1. Press the power switch (6) of "I", which means that power
supply for transmitted light illumination is switched on.
2. Put a preparation on the stage (10), turn the filters turnpla-
te (13) to position "0" (clear opening) and the 10x objective
(Fig. 2, No. 1) to the working position and bring the prepa-
ration into exact focus using the coarse and fine focusing
knobs (Fig. 2, No. 9&10).
3. Adjust the interpupillary distance and the diopter when you
are watching binocularly with both eyepieces (14).
4. Adjust the height position of the condenser (Fig. 3, No. 7)
using the condenser up-down knob (2). Adjust the transmit-
ted light dimmer (7) and the aperture diaphragm on the con-
denser (Fig. 2, No. 4) in order to get a satisfying illuminati-
on. If you watch with the 4x objective, turn the auxiliary con-
denser lens (Fig. 2, No. 5) into the optical path so that you
can get symmetrical light.
5. Adjust the fine focusing knob (5) when you change between
various objectives to observe.
6. Place some immersion oil between the 100x objective and
the cover glass and between the condenser and the slide,
when you observe with the 100x objective.

• Transmitted light source: 6 V / 20 W halogen bulb lamp with
dimmer and power supply (AC 230 V / 50 Hz).
• Exciting filters: Ultraviolet (UV), Violet (V), Blue (B), Green (G).

1. Turn the filters turnplate (Fig. 1, No. 13) to the position cor-
responding to the chosen excitation radiation (UV, V, B or G,
not 0).
2. Switch on the power supply unit (Fig. 3, No. 8) by pressing
the power switch to "I /ON". If the indicator "LIGHT" is bright,
it shows that the mercury lamp is lighted up.
3. Place a piece of white paper on the stage and remove the
objective on the working position. Adjust the condenser ad-
justing lever (4) to image the mercury lamp arc on the paper
without objective.
