II. Parts of the microscope

III. Assembling the microscope

The components for the S41-20 microscope are shipped detached for protection. Open

the styrofoam packing with care and do not leave any components attached to the

packing being removed. Do not discard any of the packing materials until all of the

components have been identified. Remove the plastic covers from the microscope's

head and the two gooseneck LED lights.

Assemble the stand connector and its supporting pillar on the vertical pillar, tightening

the fastening knobs. Attach the working arm to the stand connector, the focus block

connector to the microscope head, and then connect the working arm and focus block

connector via the focus block fixing knob.

Locate the power cord, attach it to the microscope, and then plug it in. Turn on the

power switch found on the back of the microscope stand.

IV. Using the microscope

Interpupillary adjustment

Adjust the two eyepiece tubes until only one circular field can be seen through the two

eyepieces. If two separate circles appear, the interpupillary distance is too large; if two

overlapping circles appear, the interpupillary distance is too small. The eyepiece tube

allows a flexible adjustment of the interpupillary distance between 54 and 76mm.

Focusing the microscope

To focus the sample, use the focusing knobs located on both sides of the head holder.

By turning these knobs, the microscope can be moved up or down a certain distance.

This movement is enabled by a “rack and pinion” mechanism.

Using the focusing knob, focus the sample until the image is clear. If the sample cannot

be brought into focus within the travel range of the S303/S304 pole arm and stand,

adjust the microscope head height along the vertical pillar to a working distance of

230mm from the sample. Remember to tighten the locking screw and support collar

after adjusting the height of the microscope.

Magnification and working distance

Change the optional eyepieces to increase or decrease magnification range.

Total magnification used can be calculated by multiplying the eyepiece magnification by

the objective lens magnification.

Increasing the working surface

The two gooseneck lights on this S41-20 microscope are flexible and can be directed in

many directions as needed to maximize the surface area covered by the microscope.

Likewise, the working arm can swing a full 360°to cover larger surface areas.

Adjusting the tension of focusing knob

A spanner is included in the packaging of SL41-20 for the focusing knob tension

adjustment. If necessary, use the spanner to adjust the tension.

V. Maintenance and repair

Cleaning

Keep all lenses clean. Fine dust on the surface of the lens should be gently blown off

with an air canister or wiped off with a soft lens cloth or lens tissue. Stubborn fingerprint

smudges or oil marks can be wiped off with lens tissue moistened with a small amount

of xylene or a 3:7 mixture of alcohol and ether. Never use organic solutions to clean any

other surface (especially the plastic surfaces). If necessary, please choose a mild

detergent.

Storage

After use, cover the microscope with the dust cover provided and store it in a dry and

clean place free from moisture to prevent rust. Remove the eyepieces when not in use,

and place covers on the eyepiece holders.

Repair

Do not attempt repairs on your own, particularly on the optical parts. Contact a Swift

Optical representative through our customer service email or phone line with any

issues.

VI. Troubleshooting

If you have a problem, you may be able to correct it yourself. Here are some common

issues and easy solutions you can try before calling customer support for service.
