LCD Module

This digital microscope is different than traditional microscopes --- instead of using eyepieces to look at a specimen in a traditional microscope, the LCD monitor replaces the eyepieces so you can look at the specimen on the screen by yourself or share the views with others. To begin to view specimens with your microscope, you will have to turn the LCD monitor on by turning the Power Button “On” (see Figure 3). Push the button once and shortly the Monitor On Light (red color) will come on indicating the LCD monitor is “On”. That is basically all you need to do to use the LCD screen for viewing specimens. The various keys on the LCD Module are mainly used for taking images (snapshots and video) and will be discussed later in this manual.

Illumination

To get the sharpest and best views, the proper illumination (lighting) must be chosen.

1.To turn the illuminator(s) on, see Figure 4 below which shows the following four positions on the Illuminator Switch -- - OFF, I (Bottom Illuminator), II (Top Illuminator), and III (Both Bottom & Top Illuminators).

2.The top illuminator (11) is normally for solid objects (not specimen slides) so light shines down onto the object.

3.The bottom illuminator (9) is used for specimen slides where the light shines up through the hole in the stage through the slide.

4.Having both illuminators on at the same time can provide enough light for thick and irregular specimens.

Adjusting the Lighting

Specimens of different size, thickness, and color variations will require different levels of illumination. There are two ways to change the amount of illumination when viewing a specimen; adjusting the brightness on the dial shown above in Figure 4 and changing the EV function on the LCD monitor. The EV (exposure value for brightness) function increases or decreases the brightness level by using the up or down arrow keys on the LCD monitor.

When viewing a specimen that is not transparent or dark in color, you may need to increase the amount of light to resolve certain features or details. This is best done by simply increasing the brightness of the illuminator by rotating the brightness control dial all the way to its highest setting.

Optimum lighting will be found by experimenting with adjustments as each specimen may require slightly different illumination as well as the same specimens viewed under different powers.

Viewing a Specimen

Your instrument is provided with a mechanical stage with a stage holder clamp and directional knobs –see Figure 5 below.

1.Use the clamp lever to open the clamping arm of the stage holder clamp.

2.Place a specimen slide (3” size) inside the holder and gently close the clamping arm against the slide.

3.Use the stage movement knobs to position the specimen over the opening in the stage. The rear stage movement knob moves the X axis (forward and backward) whereas the front stage movement knob moves the Y axis (side to side). Note: A vernier scale on both axes allows the exact marking and replication of an object in the field of view that the user may want to come back to.

4.Use the objective nosepiece (12) to rotate the objective lenses (11) until the 4x objective lens is directly over the specimen. Always start with the lowest power objective (4x with this microscope) which gives you 40 power and work your way up to higher powers. At 40 power you will have the widest field of view and the brightest image.

5.Look at the LCD screen while turning the focus knob (6) until the specimen comes into view. You may need to adjust the stage movement knobs (Figure 5) slightly to center the specimen in the field of view.

6.With the 4x objective lens, you can also vary the power anywhere from 40x to 160x by using the digital zoom of the LCD module. Use the direction keys on the LCD module to use the digital zoom and in the center of the screen will be an icon of a magnifier indicating at what digital zoom setting you are at.

7.For higher powers, you will need to rotate the objective nosepiece to the 10x objective and to the 40x objective for the maximum power. You will have to refocus when changing the power of the objective lenses. While using either of these objective lenses you also can increase power by using the digital zoom.

Note: When changing objective lenses, lower the stage to its lowest position so you will not hit anything during the rotation. Also, at the higher powers, be careful when raising the stage close to the objective lens so that the objective does not hit the slide specimen (or other object) and cause damage.

Using Filters

Normally most viewing or imaging will be done without filters. However, to bring out different levels of detail, experiment with changing the color of the back lighting of the specimen especially for very bright transparent specimens. To change the lighting color, rotate the color filter wheel (Figure 6 below) to the desired color. Each color is centered when you hear the click stop. You may need to refocus by adjusting the focus knob (6) slightly for best viewing. You should experiment with each of the colors to see the results.

Digital Imaging

You can take snapshots or a short video with your microscope with the built-in digital camera. With the internal storage memory, you do not need to use a PC or any other devices to do imaging. Transferring of images to your PC for saving and or printing them is easy and will be discussed later in this manual.

Note: If you are going to take images, do not connect the USB cable to your PC or damages could occur to the equipment. The USB cable is not used at all for taking images.

Settings and Information for the Digital Camera

1.In the top left of the LCD screen is the EV (Exposure Value) which adjusts the brightness level. The normal position is 0.0 and this can be adjusted in increments up to +1.5 to -1.5 by pushing the up/down directional keys.

2.In the lower right of the screen is shown the remaining internal memory available (in KB) for taking images.

3.In the lower left of the screen is shown an icon of a camera which indicates it is ready for snapshot mode. The first numbers for the resolution to use are also shown.

4.By pushing the directional keys (left/right) you change the digital zoom shown by a magnifier icon when you push the keys.

5.Push the Menu Key to:

A.Size – this sets the resolution you want for the image. The camera itself uses the 1600x1200 pixel arrangement (2MP) but you can use digital interpolation to increase the resolution or you can use lower resolutions to increase the number of images you can save in your internal storage memory. Use the directional keys to make changes.

B.Picture Effect – you can change from Normal, to black & white, negative art, or sepia.

6

C.Stamp Mode – if you desire to have the time alone, date alone, or the time and date together stamped on your images you can select which one, or you can choose to have no stamp.

D.DV record – if you want to take a short video, push the OK key and the video image will appear in the lower left of the screen. Resolution is automatically changed to low resolution for video. Press OK to finish. The rate is 25fps.

E.Setting – “on Time snap” to set the internal clock. Use the OK and directional keys to make the changes. “Stamp time” allows you to set the date and time by using the OK and directional keys. Press OK to end.

Taking Images

1.Snapshots – to take snapshots make sure you are in the camera mode (camera icon in the lower left of the screen) and you will use the Snap Key on the LCD Monitor. Push the key when ready and the image will be stored in the internal storage memory.

2.Video – change the settings to the DV record and then the movie camera icon will appear in the lower left of the screen. Use the Snap Key to begin the video and also to end it. The movie camera icon will flash to let you know that you are recording a video. Also, the elapsed time of the video is shown on the screen.

3.You can also take images (snapshot or video) by using an SD (Secure Digital) Card. Your SD card is inserted in the LCD Monitor (1). When you insert the SD card properly the SD card icon will be visible at the top of the LCD screen. On the bottom right of the screen will be shown the memory available on the SD card. When imaging this way the images are saved on the SD card and not in the internal storage memory.

Note: Inserting or removing an SD card while the LCD is on may cause the LCD to shut down and/or could damage the SD card.

Sample Images

The following specimen images left to right below were taken at 40x, 100x, 400x of Vicia Faba Young Root C.S.

Reviewing and Managing Your Images

You can review and manage your snapshots and videos on the LCD Monitor that are saved in the internal storage memory.

1.By pushing the ESC (Change) Key, you enter the stored images. Use the directional keys to select the image you want to view (the selected image will have a yellow border around it) and press the OK Key to view this image. When you push the ESC Key again it will take you back to the stored images and if you push ESC Key again, it will return you to real time. Note that if viewing a video, you can stop and start it during the video by pushing the OK Key.

2.When you have an image with the yellow border around it, you can manage it by pushing the Menu Key:

A.Protect – you can make selections by pushing the OK Key. You have a choice of “Lock” to protect this image, “Unlock” to leave the image unprotected or “Exit” the menu.

B.Delete – you can select “Current” to delete this image or you can select “All” to delete all your images. You can select “Exit” to leave the menu.

C.Cancel – select this to leave the menu.

Transferring Your Images

To transfer images to a PC or MAC, you need to have a free USB port and have an imaging program. Note: Do not disconnect the USB cable while transferring images or damage may occur.

1.You can transfer images from the internal storage memory to your PC by using the supplied Mini USB Cable. The small plug end of the cable plugs into the LCD Monitor (2) and the large plug end of the cable plugs into your PC. If the connections are proper you will see on your microscope screen “MSDC” or similar data. Your PC will automatically recognize the new hardware. Then, you will choose which program on your PC you want to transfer the images to.

2.If you used an SD card to store your images, you can transfer them to your PC using the method in # 1 above or

you can take the SD card out and use the SD card slot on your PC to transfer the images. In either way your PC will ask you to choose which program you want to transfer the images to.

Care, Maintenance, and Warranty

Your Celestron 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.

When you are done using your microscope, remove any specimens left on the stage.

Turn off the illuminator switch.

Turn off the LCD monitor.

Unplug the power cord.

Always place the dust cover over the microscope when not in use or when being stored.

Store the microscope in a dry and clean place.

Be very careful if using your microscope in direct sun light to prevent damage to the microscope or your eyes.

When moving your telescope, carry it by the “arm” with one hand and not by the focuser knob, LCD monitor, etc. Then, put your other hand under the base for support.

Clean the outside surfaces (metal and plastics) with a moist cloth.

Always unplug any cords before cleaning.

Never clean optical surfaces with cloth or paper towels as they can scratch optical surfaces easily.

Blow off dust with a camel’s hair brush or an air blower from optical surfaces.

To clean fingerprints off of optical surfaces, use a lens cleaning agent and lens tissue available at most photo outlets and when cleaning do not rub in circles as this may cause sleeks or scratches to occur.
