Safety notice

1. Transportation

As microscope is a precision instrument, handle with care, avoiding impact or abrupt movement during

transportation. Do not push or pull the microscope during using, otherwise the precision for image will be

reduced.

(1). Hold the curve and keep the microscope in balance

(2). Do not hold the focusing knob, eyepiece tubes and stage as these parts are movable.

Troubles maybe caused by such handles.

★Do not make specimen or filters fall off.

2. Working Environment

As microscope is a precision instrument, improper using will make it unworkable or reduce its precision.

(1). Do not expose the microscope in the sun directly.

(2). Temperature range is 0-40 and the max. humidity is 85%.

(3). Avoid high temperature and humidification otherwise there will be fog or mold on the lens.

(4). Avoid violent vibration as the vibration will reduce the images quality.

(5). Place microscope on a stable plane and keep it in balance. Keep the environment breezy and cover the

microscope with the dust-cover.

(6). Do not place microscope in moist room to avoid short circuit. Please turn off the power supply as soon

as water drop in the microscope. If there are other things unsafe come into the microscope may cause short

circuit too, please stop using and contact with manufacturer.

3. Focusing knob

Never turn the left and right focusing knob in the adverse direction at the same

time. Do not turn the coarse focusing knob when the stage reaches max position.

These improper operations will make focusing structure unworkable.

4. Clamp

The clamps fix the microscope firmly during

transportation, please remove them before using.

5. Do not take the microscope apart

As it will be damaged. Such operations might have bad effect on the performance and make user get an

electric shock or injured. Please contact with manufacturer if there is any problem.

6. Make sure the voltage

There is correct input voltage in the label on microscope. Make sure

the voltage in your position is right. Improper input voltage may

cause short circuit and fire. The microscope will be damaged.

Input voltage in the label: 100-240V, 50/60Hz

7. Use the spare parts supplied by the manufacturer

The bulb, fuse and electronic cord have been assembled already in the factory and please make sure to use the

spare parts of them supplied by the manufacturer. Improper bulb, fuse and electronic cord will destroy

microscope and cause fire. Please make sure to use PE electronic cord when using extra-long electronic cord.

Spare bulbs: halogen bulb 12V20W (or 12V30W)

Spare fuse: 250V 1A delayed model, mini type fuse

8. Mounting the bulb

Never touch the surface of bulb with your hand directly. Please use gloves or cloth material when you

mount the bulb to avoid leaving fingerprints. Fingerprints or stains should be wiped off with a tissue

moistened with a small amount of alcohol. The fingerprints will etch on the bulb s surface and make

brightness lower and life cycle shorter.

Please make sure the bulb’s touching points are Ok as it will not light or short circuit if the bulb’s touching

points are damaged. Insert the bulb’s legs into the bulb holder firmly. The bulb will go out if its legs have

not been inserted into the holder firmly. Such Operation may cause short circuit or smoking. At last, please

make sure if the collector has been mounted properly.

9. Temperature for illumination

There will be high temperature when the bulb is lightened, never move the collector when the bulb is

lightened. Do not touch the bulb within 30 minutes after it has been turned off. Make sure the bulb has been

cooling for enough time (at least 30 minutes) to avoid scald. Do not put fiber, papers and incendive things (eg.

Gasoline, aether, methanol and ethanol) close to the bulb.

10. Make sure to turn off the power supply before assembling microscope,

replacing bulb or fuse.

11. Observing with oil immersion

Using small amount of oil immersion is enough. The redundant oil will adhere to stage or

condenser and these will reduce microscope’s performance.

Get rid of the redundant oil or clean the lens by using aether or pure alcohol according to this

instruction. Pay attention during process as these things are incentive

12. Operating the microscope only indoor and under the altitude 2000m,

IP52 grads.

If the equipment is used in manner not specified by the manufacturer, the equipment may be

impaired.

2.2 Optical parameter

1. Optical parameter

Objectives: infinite plan achromatic objectives

Objectives N.A. Cover glass thickness(mm) W.D. mm Dry/Oil

4X 0.1 0.17 25 Dry

10X 0.25 0.17 6.7 Dr

0.65

0.6

2. Eyepiece: WF10X/22mm

2.3 Nomenclature

Total magnification

Total magnification = Eyepiece’s magnification * objective’s magnification

Numerical aperture (N.A.)

N.A. value will affect resolution and image’s brightness, it is the leading parameter for

objectives. N.A.= n*sin

n stands for refractive index of the medium between objective and specimen or condenser (air or oil

immersion)

a stands for half angle of max. aperture angle in the axis

The image will be sharper and brighter when the N.A. value is bigger

Resolution

Resolution can be measured by the distance value from one point to another one which could

be distinguished on the object surface
