Key Components:
- Siedentopf Head: Fully rotatable for shared viewing, equipped with trinocular port for camera attachments.
- Eyepieces: Interchangeable wide-field 10X and 25X glass eyepieces, ergonomically tilted at 30 degrees.
- Revolving Nosepiece: Holds 4 DIN Achromatic objective lenses (4X, 10X, 40X, 100X Oil).
- Objective Lenses: Provide magnification levels of 40X, 100X, 250X, 400X, 1000X, 2500X.
- Mechanical Stage: Double-layered with a secure slide holder for precise specimen positioning.
- Abbe Condenser: Illuminates slide specimens from below, with adjustable brightness.
- Coarse and Fine Adjustment Knobs: For precise focusing.
- LED Light Source: Brilliant and adjustable illumination.
- Camera Port: Dedicated port for connecting microscope cameras (not included).
3. Setup Instructions
Follow these steps to set up your microscope for the first time.
- Unpacking: Carefully remove all components from the packaging. Retain the original packaging for future storage or transport.
- Placement: Place the microscope on a stable, level surface away from direct sunlight, excessive dust, and vibrations.
- Head Installation: Gently attach the Siedentopf head to the microscope body. Secure it with the set screw, ensuring it is firmly in place but not overtightened.
- Eyepiece Insertion: Insert the desired wide-field eyepieces (10X or 25X) into the eyepiece tubes on the Siedentopf head.
- Objective Lens Installation: Ensure the objective lenses are securely screwed into the revolving nosepiece. The 4X objective should be aligned with the light path for initial setup.
- Power Connection: Connect the power cord to the microscope's power input and then to a standard electrical outlet (110 Volts AC).

4. Operating Your Microscope
4.1 Powering On and Illumination
Locate the power switch on the base of the microscope and turn it on. Adjust the brightness of the LED illumination using the dimming handwheel to achieve optimal viewing conditions for your specimen.

4.2 Placing a Specimen Slide
Place your prepared specimen slide onto the mechanical stage. Use the slide holder clips to secure the slide in place.

4.3 Adjusting Magnification
Rotate the revolving nosepiece to select the desired objective lens. Start with the lowest magnification (4X or 10X) for initial viewing and then gradually increase as needed. The total magnification is calculated by multiplying the eyepiece magnification by the objective lens magnification.

4.4 Focusing
Use the coarse adjustment knob for large focus changes, typically with lower magnification objectives. Once the image is roughly in focus, use the fine adjustment knob for precise focusing, especially at higher magnifications.
4.5 Using the Abbe Condenser
The Abbe condenser, located beneath the stage, helps to concentrate and direct light through the specimen. Adjust its height and the iris diaphragm to control contrast and resolution. For optimal viewing, the condenser should be raised close to the stage for higher magnifications and lowered for lower magnifications.

4.6 Using the Trinocular Port (Camera Compatibility)
The SW350T features a dedicated trinocular port for attaching microscope cameras (sold separately). This allows for digital imaging, live streaming, and recording of your observations. To use, simply insert your compatible microscope camera into the trinocular port and follow the camera's specific instructions for setup and software installation.

5. Maintenance and Care
Proper maintenance will extend the life and performance of your microscope.
- Cleaning Optics: Use only specialized lens cleaning paper and optical cleaning solution for objective lenses and eyepieces. Gently wipe in a circular motion from the center outwards. Avoid touching optical surfaces with bare hands.
- Cleaning Body: Wipe the microscope body with a soft, damp cloth. Do not use harsh chemicals or abrasive cleaners.
- Storage: When not in use, cover the microscope with the provided dust cover to protect it from dust and debris. Store in a cool, dry place.
- Handling: Always carry the microscope by its arm and base. Avoid sudden movements or impacts.
- Oil Immersion (100X Objective): If using the 100X oil immersion objective, ensure to clean off immersion oil immediately after use to prevent damage to the lens.
6. Troubleshooting Guide
Refer to the table below for common issues and their solutions.
| Problem | Possible Cause | Solution |
|---|---|---|
| No illumination | Power switch off, power cord disconnected, brightness knob set to minimum. | Turn on power switch, check power cord connection, increase brightness. |
| Image blurry or out of focus | Incorrect focus adjustment, slide upside down, objective lens not fully engaged. | Adjust coarse and fine focus, ensure slide is correctly oriented, rotate nosepiece until objective clicks into place. |
| Dark or uneven field of view | Condenser not adjusted correctly, iris diaphragm closed too much, objective lens dirty. | Adjust condenser height, open iris diaphragm, clean objective lens. |
| Dust or spots visible in image | Dust on eyepiece, objective, or slide. | Clean eyepieces, objectives, and slide using appropriate cleaning methods. |
