AmScope B120 Siedentopf Binocular Compound Microscope User Manual

1. Introduction et plusview

The AmScope B120 Siedentopf Binocular Compound Microscope is designed for high-magnification biological and educational applications. It features a Siedentopf binocular head for comfortable viewing, a forward-facing nosepiece with four DIN achromatic objectives, Brightfield LED illumination, and a double-layer mechanical stage for precise specimen manipulation.

This microscope provides clear, color-corrected magnified images, making it suitable for detailed inspection and dissection of specimens where two-dimensional images are desired.

2. What's In The Box

Lors du déballage, veuillez vérifier que tous les composants suivants sont présents :

• AmScope B120 microscope with double-layer mechanical stage
• (4) DIN Standard Objectives: 4x, 10x, 40xS (spring-loaded), and 100xS (spring-loaded, oil immersion)
• 10x widefield eyepieces, one pair
• Color filter, blue
• Immersion oil, one bottle
• Cache-poussière
• Instructions (ce manuel)

3. Guide de configuration

1. Déballage: Carefully remove all components from the packaging. Place the microscope body on a stable, level surface.
2. Fixation de la tête : Loosen the head locking screw on the microscope body. Gently insert the Siedentopf binocular head into the top opening of the microscope body. Tighten the locking screw to secure the head.
3. Insertion des oculaires : Insert the two 10x widefield eyepieces into the eyepiece tubes on the binocular head.
4. Connexion de l'alimentation : Connect the power cord to the microscope's power input and then to a standard 110V or 220V AC outlet. Ensure the power switch is in the "Off" position before connecting.
5. Réglages initiaux :
   • Distance interpupillaire : While looking through the eyepieces, adjust the distance between the two eyepiece tubes until you see a single, clear circular field of view. The inter-pupillary adjustment range is 53 to 77mm.
   • Réglage dioptrique : If one eye is stronger than the other, use the diopter adjustment ring on one of the eyepiece tubes (usually the left one) to compensate. Focus on a specimen with your non-diopter eye first, then adjust the diopter ring for the other eye until both eyes see a sharp image.

4. Mode d'emploi

4.1 Mise sous et hors tension

Locate the power switch, usually on the side or back of the microscope base. Flip the switch to the "On" position to activate the LED illumination. Flip it to "Off" when not in use.

4.2 Placing a Specimen

1. Rotate the nosepiece to select the lowest power objective (4x).
2. Abaisser le s mécaniquetage using the coarse focus knob to create enough space.
3. Place your prepared slide onto the mechanical stage, en le fixant avec le staget des clips.
4. Use the X-Y axis stage manipulation knobs to center the specimen directly under the objective lens.

4.3 Mise au point

• Mise au point grossière : While looking through the eyepieces, slowly raise the stage using the coarse focus knob until the specimen comes into approximate focus.
• Mise au point précise : Once the image is roughly focused, use the fine focus knob for precise adjustments to achieve a sharp, clear image.
• Objectifs changeants : To increase magnification, rotate the nosepiece to the next objective (e.g., from 4x to 10x). The microscope is parfocal, meaning the image should remain largely in focus, requiring only minor adjustments with the fine focus knob.
• Note: The 40xS and 100xS objectives are spring-loaded to prevent damage to the slide or objective if they accidentally contact.

4.4 Réglage de l'éclairage

• Contrôle de la luminosité des LED : Use the dimmer knob (if present) on the microscope base to adjust the intensity of the LED light source.
• Condensateur d'Abbe : The 1.25 NA Abbe condenser is located beneath the stage. Use the condenser adjustment knob to raise or lower the condenser, controlling the light path and optimizing illumination for different objectives.
• Diaphragme à iris: The iris diaphragm is located within the Abbe condenser. Adjust its lever to control the amount of light illuminating the specimen and to improve contrast. Generally, for higher magnification, you may need to open the diaphragm more.

4.5 Using the 100xS Oil Immersion Objective

The 100xS objective requires immersion oil for optimal resolution. Follow these steps:

1. Focus on your specimen using the 40xS objective.
2. Rotate the nosepiece halfway between the 40xS and 100xS objectives.
3. Place a small drop of immersion oil directly onto the center of the illuminated area of the slide.
4. Carefully rotate the 100xS objective into place, ensuring it makes contact with the oil drop. The spring-loaded mechanism will prevent excessive pressure.
5. Use only the fine focus knob to bring the image into sharp focus.
6. After use, always clean the 100xS objective and the slide thoroughly with lens paper and a suitable lens cleaning solution to remove all oil residue.

5. Entretien

• Nettoyage des lentilles : Use only specialized lens paper and lens cleaning solution for optical components. Gently wipe the lenses in a circular motion. Avoid touching lenses with bare fingers.
• Nettoyage du corps : Essuyez le corps du microscope avec un chiffon doux et sec.amp tissu. Évitez d'utiliser des produits chimiques agressifs ou des nettoyants abrasifs.
• Stockage: 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 away from direct sunlight and extreme temperatures.
• Oil Immersion Care: Always clean the 100xS objective immediately after use to prevent oil from drying on the lens.
• Moving the Microscope: Always carry the microscope by holding the arm with one hand and supporting the base with the other.
