40x, 400x, 1600x 3MP Digital Microscope with Screen 

Introduction

Thank you for purchasing the LCD Digital Microscope (LDM) with a 3.5” monitor. Your 

microscope is a precision optical instrument, made of the highest quality materials to 

ensure durability and long life. 

Before attempting to use your microscope, read through the instructions to familiarize 

yourself with the functions and operations to maximize your enjoyment and usage. See 

the microscope diagrams to locate the parts discussed in this manual. 

This microscope provides high powers from 40x up to 400x (up to 1600x with digital 

zoom). This microscope is ideally suited for examining specimen slides of yeasts and 

molds, cultures, plant and animal parts, fibers, bacteria, etc. You can also examine small 

objects such as coins, stamps, PC boards, insects, and other objects especially at the 

lower powers. 

This microscope does not have an eyepiece that is used in traditional microscopes. 

You will view specimens on the LCD screen which are easy to see and enjoy them with 

others. You can also take snapshots or short videos with the built-in digital camera. 

The final section provides simple care and maintenance tips for you to follow to 

ensure that your microscope provides you with years of quality performance, usage, and 

enjoyment.

Microscope Operation

Before looking at specimens you must turn the LCD on, turn on the illumination, and 

understand how to use the mechanical stage and then you are ready to begin viewing. 

Figure 3 

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 view 

with others. To begin to view specimens with your microscope, you will have to turn the 

LCD monitor on by turning the Power Button “Power” (see Figure 3). Push and hold the 

button down until the Red LED comes 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 (II) is normally for solid objects (not specimen slides) so light shine 

down onto the object. The top illuminator was designed to be used at low power (4 x 

objectives) as higher power objective lenses (10x & 40x) will block the light. If you need to

use high power to observe solid objects, use a secondary light (desk lamp, etc.) for 

Illumination. 

3. The bottom illuminator (I) 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. 

Figure 4 

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 5 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 “left” or “right” 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.

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. 

Settings and Information for the Digital Camera

After power on the LCD monitor, there are three choice menus. 

Camera: 

1. In the Top right of the LCD screen (Figure 5-4), mean we are in the camera mode. 

2. In the Top left of the LCD screen (Figure 5-1) 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 -2 to +2 by pushing the Left/Right directional keys. 

3. In the screen(Figure 5 – 2) is the digital zoom feature, using the directional keys 

(up/down) to zoom out/in, Maximum with 4x digital zoom feature.

4. The picture setting Mode (Figure 5 – 3) – the normal (default setting) is “Single” for 

taking snapshots one at a time as you choose. You can Choose “Continuous” to take 

consecutive picture. 

a) Size (Figure 5 – 5) – this sets the resolution you want for the image. The camera 

itself uses the 2560x1920 pixel arrangement (5MP) 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.

b) Quality – The quality can provide fine, standard, economy image, 

c) White balance– you can change the different white balance to observe different 

slice. 

5. In the bottom right of the screen (Figure 5 – 6) is shown an estimate of the remaining 

snapshot images left in the internal memory or SD card

DV Record: 

1. In the Top right of the LCD screen (Figure 6-3), mean we are in the DV record mode. 

2. In the Top left of the LCD screen (Figure 6-1) 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 -2 to +2 by pushing the Left/Right directional keys. 

3. In the screen(Figure 6 – 2) is the digital zoom feature, using the directional keys 

(up/down) to zoom out/in, Maximum with 4x digital zoom feature.

4. The DV Record can save in VGA or QVGA MP4 movie record (Figure 6 – 4).

5. In the bottom right of the screen (Figure 6 – 5) is shown an estimate of the remaining 

snapshot images left in the internal memory or SD card 

Figure 6 

Picture View:

1. Into the “Picture View”, the picture is Recent photographs. 

2. Using the “MENU” key. 

a) Delete – delete single, all the picture or delete your select picture. 

b) Copy to card – you can copy the picture from the build-in memory card to SD 

card. 

c) File Protect 

d) Thumbnail – view the picture in nine.

Maintenance

Your LCD Digital 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. 

z When not microscope is not in use, remove any specimens left on the stage. 

z Turn off the illuminator switch. 

z Turn off the LCD monitor. 

z Unplug the power cord. 

z Always place the dust cover over the microscope when not in use. 

z Store the microscope in a dry and clean place. 

z Be very careful if using your microscope in direct sun light to prevent damage to the 

microscope or your eyes. 

z When moving your microscope, 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. 

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

z Always unplug any cords before cleaning. 

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

surfaces easily. 

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

z To clean fingerprints off of optical surfaces, use a lens cleaning agent 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. 

z Never disassemble or clean internal optical surfaces. This should be done by 

qualified technicians at the factory or other authorized repair facilities. 

z When handling glass specimen slides, use care as the edges can be sharp.
