• Monocular Head: The viewing tube where the eyepiece is inserted. Angled at 45 degrees for comfortable viewing.
• Eyepiece (WF10X): The lens through which you look to observe the specimen.
• Objective Turret (Revolving Nosepiece): Holds the objective lenses and allows for easy switching between magnifications.
• Objective Lenses (4X, 10X, 40X, 100X): Lenses that magnify the specimen.
• Mechanical Stage: A platform with clips to hold the specimen slide, featuring X-Y movement controls for precise positioning.
• Coarse Focus Knob: Used for large adjustments in focus.
• Fine Focus Knob: Used for small, precise adjustments in focus.
• Illumination System: Built-in LED light source for illuminating the specimen.
• Abbe Condenser with Iris Diaphragm: Located beneath the stage, it focuses light onto the specimen and controls the amount of light.
• Built-in 3MP USB Camera: Integrated camera for digital imaging and video capture.

5. Setup

1. Unpacking and Placement: Carefully remove all components from the packaging. Place the microscope on a stable, level, and vibration-free surface.
2. Eyepiece Installation: Insert the WF10X eyepiece into the monocular head.
3. Objective Lens Installation: The objective lenses (4X, 10X, 40X, 100X) are typically pre-installed on the revolving nosepiece. Ensure they are securely screwed in.
4. Power Connection: Connect the power adapter to the microscope's power input and then plug it into a suitable electrical outlet (240 Volts).
5. USB Camera Connection and Software Installation:
   • Connect the provided 6' USB cable from the microscope's USB port to your computer.
   • Insert the included CD with the camera software driver into your computer's CD drive.
   • Follow the on-screen instructions to install the camera software. The software is compatible with Windows XP/Vista/7/8, and Mac OS X 10.6.8 and higher.

6. Operating Instructions

6.1 Powering On

Locate the power switch on the microscope base and turn it on. The LED illumination should light up.

6.2 Adjusting Illumination

Use the dimmer control knob on the base to adjust the brightness of the LED illumination. Adjust the iris diaphragm on the Abbe condenser to control contrast and resolution.

6.3 Placing a Specimen

Place a prepared microscope slide onto the mechanical stage, securing it with the stage clips. Use the X-Y stage control knobs to center the specimen area you wish to observe under the objective lens.

6.4 Focusing

1. Rotate the objective turret to select the lowest power objective (4X).
2. While looking through the eyepiece, slowly turn the Coarse Focus Knob to bring the specimen into approximate focus.
3. Once roughly focused, use the Fine Focus Knob to achieve a sharp, clear image.

6.5 Changing Magnification

To increase magnification, rotate the objective turret to the next desired objective (e.g., 10X, 40X). The microscope is parfocal, meaning minimal fine focus adjustment should be needed when switching objectives.

6.6 Using the 100X Oil Immersion Objective

The 100X objective requires immersion oil for proper function. Place a small drop of immersion oil directly onto the specimen slide in the area to be viewed. Carefully rotate the 100X objective into the oil drop, ensuring no air bubbles are present. Focus using only the fine focus knob. After use, clean the 100X objective and slide immediately with lens cleaning solution.

6.7 Using the Digital Camera

After installing the camera software, launch the application on your computer. The software provides a live video feed from the microscope. You can:

• Capture Still Images: Use the software interface to take high-resolution still photographs of your specimen.
• Record Video: Record live video footage of moving specimens or processes.
• Measurement Functions: Utilize built-in tools for on-screen measurements.
• Image Editing: The software includes basic image editing and processing functions.

7. Maintenance

• Cleaning Lenses: Use only specialized lens cleaning paper and lens cleaning solution. Gently wipe the lens surfaces. Avoid touching lenses with bare fingers.
• Cleaning the Body: Wipe the microscope body with a soft, damp cloth. Do not use organic solvents.
• Storage: When not in use, cover the microscope with the provided dust cover and store it in a dry, dust-free environment.
• Bulb Replacement: The microscope uses an LED illumination system, which has a long lifespan and typically does not require bulb replacement.
