Frequently Asked Questions - AY11684 Barska

How do I clean the microscope lenses?

Use a soft lens brush to remove dust, then gently wipe with lens paper moistened with isopropyl alcohol. Avoid using tissues or cloth that may scratch the lens.

What is the maximum magnification?

The maximum magnification is 1000x when using the oil immersion objective (100x) with the 10x eyepiece. You can also achieve 2000x with the 20x eyepiece, but image quality may degrade.

Does the microscope come with batteries?

No, the microscope does not include batteries. You need to insert 3 AA batteries for the LED illumination. Alternatively, you can power it via a USB cable (not included).

How do I use the oil immersion objective?

First, focus on the sample using the 40x objective. Then, place a drop of immersion oil on the slide. Rotate the 100x objective into position, ensuring it touches the oil. Use the fine focus knob to sharpen the image. After use, clean the lens immediately.

Why is the LED light not working?

Check if the batteries are inserted correctly or if the USB cable is connected. Also, ensure the brightness adjustment knob is not turned all the way down. If still not working, replace the batteries or test with a different USB power source.

Initial Set Up The Microscope

1. Carefully remove the microscope and parts from the carrying case and set them on a flat surface
2. Remove the dust cover from the microscope.
3. Decide if you want to view the specimen with the eyepiece or the LCD screen and carefully attach the appropriate viewing device to the tube of the microscope.

Eyepiece has magnifi cation of 40x,100x, 400: LCD screen has a magnifi cation of 32x, 80x, 320:

1. Plug the small cable from the AC adapter into the socket on the back of the base. Power connection (220 V or 110V) is required for observations using the electrical LED lighting and the electronic LCD eyepiece (screen module). Insert the plug end of the AC adapter into the proper power source

Illumination

To get the sharpest and best views, the proper illumination or lighting must be chosen

Oblique Lighting

Or top lighting is normally for solid objects (not on a specimen slide) so light shine down onto the object.

Transmitted Lighting

Or bottom lighting is used for specimen slides where the light shines up through the hole in the stage through the slide.

Having both oblique and transmitted lights on at the same time can provide enough light for semi-transparent specimens.

The lighting switches are located near the base of the microscope on either side of the microscope. Adjust the level of brightness by turning the switch slide.

Using the Microscope with the LCD Screen

Carefully place the LCD screen into the tube of the microscope.

1. Begin each observation at the lowest magnification. To adjust the positioning of the specimen move the microscope table, using the focusing wheel completely down and then turn the lens turret until it engages on the lowest magnification (the 4x-objective is vertical)
2. Place specimen directly under the objective of the microscope stage and exactly above or below the illumination, if the specimen is on a microscope slide clamp it onto the stage of the microscope. For this, move the lever for the clamping mounting plate to the side, put the slide onto the stage and carefully allow the clamping mounting plate to return onto the prepared slide.
3. Then switch on the LCD monitor, by pressing the power switch on the screen module; the red operating light will light up. Look at the LCD screen and adjust lighting and focusing wheel until the image is sharp. With the stage you can now center the object at the desired place on the LCD monitor.
4. For higher magnification turn the lens turret to a higher setting (objectives 10x and 40x).

Votes: Before you change the objective setting, first move the microscope table fully downwards. This will avoid possible damage to the objective lens and to the slide.

The higher the magnifi cation, the more light is needed for a good image quality

Depending on the preparation in use, higher magnifi cation in individual cases will not lead to a better picture. The magnifi cation is altered by changing the objective. This alters the sharpness of the image which must be adjusted by the focusing wheel. Proceed here very carefully, if you raise the microscope table too quickly, the objective and the slides can touch each other and be damaged

1. The magnifi cation factor of the LCD eyepiece amounts to 10x. Ir combination with the 4x-objective we obtain a total magnifi cation o 40x, i.e. 1 mm of the object is shown as 40 mm on the LCD monitor. With the 10x objective we have a total magnifi cation of 100x correspondingly, with the 40x objective 400x.

2. To zoom in digitally, press the "up" or "down" arrow keys located on the right of screen. The digital magnification of the image can be zoom with set with a factor from 1 to 8.

Colored Wheel Filter Disc

The color wheel fi Iter disc is located beneath the microscope table helps you when viewing very bright or transparent specimens. For this please select the suitable color depending upon the object being observed. The components of colorless or transparent objects (e.g. grain containing starch, single-celled organisms) will be much easier to recognize. Filter colors are violet, yellow, light green, green and blue.

System Requirements

for USB Connection / Memory Card Use

• Windows operating system (Window XP or Windows Vista)
• USB connection
• Media program
  (e.g. Image processing program, program for playing fi lms
• Memory card
• Memory card reader

Image Output and Storage

The LCD Screen offers you three possibilities for image output and storage: Directly on the screen, on an SD memory card (NOT included) or through the USB cable.

1. LCD Screen

You can view the image directly on the LCD screen. The screen has an internal storage capacity of 128 MB for your photographs.

2. SD Memory Card (NOT included)

You can store your photographs on an SD memory card (SD, Secure Digital) (NOT included). The memory card slot of the LCD Screen is located on the bottom of the screen beside the USB connection. To use, push the memory card, with the contacts at the front, into the slot, until they engage with a faint click. If the installation is correct, a memory card symbol appears above on the LCD monitor. To remove the SD card press and release the memory card, which after a faint click, can be taken out of the slot. Your photographs are now transportable.

3. USB Cable

If you connect your microscope to the PC using the included USB cable, you can transfer the photographs to the PC through the USB cable. The USB connection of the LCD Screen is located on the bottom of the screen module beside the memory card slot. Insert the smaller plug of the USB cable into the socket on the microscope and the larger plug into a free USB port in your computer. After a successful USB connection, the computer's operating system will recognize new hardware and then two new drive assemblies will be initialized.

These are marked as "removable data carrier e" and "removable data carrier f", the letters vary depending upon the number of drive assemblies in your computer. They are made available on the work station, as well as in Windows Explorer. The fi rst drive assembly

BARSKA

recognized (e:) is the internal memory of the screen module. The second (f:) contains – if a memory card is inserted – the contents of the card.

Caution: When taking a photograph, no USB connection between PC and microscope may exist. Before you interrupt the USB connection or switch the screen module off, you must remove or eject the screen module (removable data carrier e:) in the PC with the help of the hardware assistant and "deactivate" the card drive assembly (removable data carrier f:) ! If the drive assemblies are not deactivated, the PC might "crash" or there may be a loss of data.

Using the Microscope with the Eyepiece

1. Remove the LCD eyepiece from the tube and carefully place the eyepiece into the microscope tube.
2. Place specimen directly under the objective of the microscope stage and exactly above or below the illumination if the specimen is on a microscope slide clamp it onto the stage of the microscope. For this, move the lever for the clamping mounting plate to the side, put the slide onto the stage and carefully allow the clamping mounting plate to return onto the prepared slide.
3. After you have set up the microscope with the corresponding illumination, look through the eyepiece.
4. Begin each observation at the lowest magnification. Use the 4> Objective Lens by rotating the Objective Lens Turret so that the 4x Objective Lens is aiming at the center of the Stage (when it is in the proper position it will click into place). The 4x Objective Lens will give a 40x (40 power) view with the 10x Eyepiece. Final Power is calculated by multiplying the Objective Lens Power by the Eyepiece Power (e.g., 4 × 10 = 40 ).
5. Focus the microscope by slowly turning the Focusing Knob, until an image forms in the Eyepiece.
6. To increase magnification, rotate the Objective Lens Turret to center the 10x Objective Lens over the specimen for 100x, or the 40x Objective Lens for 400x, or change the eyepiece from 10x to 16x. When using higher magnifications focusing becomes more critical and the objective lens will come closer to the specimen in order to reach focus. Don't let the lens touch the slide as you may break the slide and damage the lens.

Care and maintenance

The microscope is a precision optical instrument and should be treated with care at all times. Follow these care and maintenance suggestions and your microscope will need very little maintenance throughout its lifetime.

• Turn off the illuminator switch
• Unplug the power cord
• Carefully remove viewing instrument (screen or eyepiece) from the body of the microscope
• Make sure that dust or moisture do not come into contact with your microscope
• Be very careful if using your microscope in direct sun light to prevent damage to the microscope or your eyes
• When moving your microscope, carry it by the "arm" with one hand and not by the focuser knob, monitor, etc. Then, place put your other hand under the base for support
• Always unplug any cords before cleaning and clean the outside surfaces (metal and plastics) with a moist cloth
• Remove dust with a camel's hair brush or an air blower from optical surfaces
• Never clean optical surfaces with cloth or paper towels as they can scratch optical surfaces easily

BARSKA

• To clean fi ingerprints off of optical surfaces, use a lens cleaning agen and lens tissue available at most retail photo stores and when cleaning do not rub in circles as this may cause sleeks or scratches to occur
• Never disassemble or clean internal optical surfaces. This should be done by qualified technicians at the factory or other authorized repair facilities
• When handling glass specimen slides, use care as the edges may be sharp
• Remove any specimens left on the stage
• After usage, place the dust cover over the microscope and stow the microscope and accessories in their correct place in the carrying case
• Store the microscope in a dry, cool clean place
