BEFORE USEThis manual gives explanations of the illumination bases SZH-I LLK, -I LLB and -I LLD. It is recommendedthat you also read the manual for the microscope SZH, and in the case of photomicrography, the manualfor the photomicrographic attachments in use, in order to obtain maximum performance.

Observe the following procedures carefully;

1. Operation

CD Avoid exposure of the illumination base to direct sunlight, high temperature and humidity, dust andvibration. (Ambient temperature for operation: OOC - 40°C)

® Always handle the illumination base with care and avoid abrupt motions and shock. Specially do notexpose the illumination base SZH-l LLD to vertical shock in order to protect the built-in cooling fan.

@ Use the microscope on a desk surface of no more than 3° inclination.

@ When using the pillar S-P400 (pillar length: 400mm) in conjunction with the objective O.5X andO.75X, both optionally available, check the stability of the microscope after assembly of these units.

1. Mounting the zoom microscope body:

CD Mount the zoom microscope body on the illumination base in front of the pillar as shown in Fig. 1,left (marked with a circle); to prevent the microscope body from overturning. (Fig. 1)

® Securely clamp the drop prevention collar next to the microscope body. (Fig. 2)

Do not leave space here.

Fig. 1

2. If liquid is spilled on the illumination base:

CD Disconnect the power cord from the AC outlet.

® Wipe off spilled liquid with a dry cloth or a towel.

@ Wipe the light exit window lens evenly with dry cotton gauze.

@ If liquid spills into the base, contact your Olympus dealer.

Fig. 2

3. Use of the auxiliary output jack provided on each illumination base:

Do not use this auxiliary output jack for any attachment other than the coaxial vertical illuminatorSZH-I LLC or the simple illuminator LSGA (Max. 6V 20W).

2. Maintenance and Storage

CD Optical glass surfaces must always be kept clean. Dust on lens surfaces should be blown off bymeans of a hand blower. Carefully wipe oil or fingerprints off the glass surfaces with gauze moistened with a small amount of xylene or a 3: 7 mixture of alcohol and ether.

® Do not use organic solution to wipe the surfaces of non-optical components. Plastic parts, espe-cially, should be cleaned with a neutral detergent.

@ Do not disassemble any part of the instrument.

@ When not in use, the instrument should be covered with the dust cover provided.

@ Do not leave smudges or fingerprints on the bulb portion of the halogen lamp. If necessary, itshould be wiped clean with cotton gauze slightly moistened with a 3: 7 mixture of alcohol andether, or benzene.

® Before replacement of the burned bulb, let it cool completely.

The light beam emitted from the halogen bulb goes through the collector lens and heat filter for elimination of heat radiation. Then the beam is split into 2 ray bundles by the paired sliding lenses andselector lenses, and, in Koehler mode, illuminates the specimen. The illumination selector lenses aredesigned to provide optimum intensity at any zoom magnification. Moving the sliding lenses permitsselection of optimum illumination among oblique, darkfield, low contrast (critical) illumination, etc.

• Brightfield

The light beam emitted from the halogen bulb goes through the heatfilter, which removes the heat radiation. Then the beam is diffused bythe frosted filter to evenly illuminate the specimen surface. (Fig. 3)

• Darkfield

After the heat radiation is removed by the heat filter, part of the lightbeam that proceeds toward the specimen directly is cut off by the light

excluding plate. The rest of the light is reflected by the cylindricalmirror and illuminates the specimen at an oblique angle, larger than theconstant angle (o).Therefore, only the light that is reflected from the specimen passesthrough the objective, to be observed through the eyepieces, while therest of the light is not visible (darkfield effect).

2) Oblique illumination

This illumination is employed to improve visual contrast of a transparent specimen floating in liquidor similar applications.

Operating procedure:

Looking through the eyepieces, gradually tilt the oblique illuminator knob until the specimen imagecan be observed in good contrast.

* Oblique illumination is obtained without the frosted filter 45LP engaged when the objective magnification is lX, without the adapter SZH-STADl for mechanical stage or round stage.

* If the frosted filter 45 LP is used, however, oblique illumination can be obtained at objectivemagnifications other than 1X, although the illumination might be uneven.

* Uneven illumination may be expected at low magnifications.

•

------------------------------.

3) Low contrast illumination

This illumination is employed when it is necessary to observe stained tissues in detail with flat lighting.

Operating procedure:

• Place the frosted filter 45LP under the stage glass.• Turn the oblique illuminator knob until it reaches the stop position.

* At this position, no oblique illumination can be obtained.

White dotpositions

2) Crossed filter position

a) Looking through the eyepieces, rotate the analyzer until the field of view is most darkened, with

total extinction at the crossed (Nichol's) filter position.* Looking through the eyepieces, remove the specimen to confirm this condition.

b) At this position, the white dot on the analyzer is either closest to the operator or 1800

rotated .

6. Observation

A. To observe the birefringence of a specimen:

1) Set the analyzer and polarizer to the "crossed filter" position.
