- Oculaire : Là où vous regardez view the specimen. The D120A-MS includes WF10x and WF16x eyepieces.
- Monoculaire ViewChef d'entreprise : The upper part of the microscope containing the eyepiece tube. This model features a dual-view head with a fixed 45-degree inclined tube and a vertical port.
- Embout nasal rotatif : Holds the objective lenses and allows for easy switching between magnifications.
- Objectifs : The primary magnification components (4x, 10x, 40xS, 100xS oil).
- Mécanique Stage: A platform where the specimen slide is placed, with controls for precise X-Y movement.
- Stage Clips : Secure the specimen slide on the mechanical stage.
- Coarse Focus Knob: Large knob for rapid focusing adjustments.
- Fine Focus Knob: Small knob for precise focusing adjustments.
- Illuminator (Light Source): Situé sous le stage, provides light for viewing. This model uses variable-intensity tungsten illumination.
- Condensateur d'Abbe : Located below the stage, focuses light onto the specimen. Features a 1.25 NA and an iris diaphragm.
- Diaphragme à iris: Controls the amount of light passing through the specimen.
- Base: The stable bottom support of the microscope.
5. Assemblage et configuration
Follow these steps to set up your microscope for initial use:
- Déballage: Retirez délicatement le microscope et tous ses accessoires de leur emballage. Conservez l'emballage d'origine pour tout transport ou stockage ultérieur.
- Placement: Place the microscope on a sturdy, level surface, away from vibrations and direct sunlight.
- Installation de l'oculaire : Insert the desired eyepiece (WF10x or WF16x) into the inclined eyepiece tube of the monocular head. Gently twist to secure it.
- Objective Installation: The objective lenses are typically pre-installed. If not, carefully screw each objective into the revolving nosepiece in increasing order of magnification (4x, 10x, 40xS, 100xS). Ensure they are finger-tight.
- Connexion électrique : Connect the power cord to the microscope's power input and then to a standard 110V electrical outlet.
- Cache-poussière : When not in use, cover the microscope with the provided dust cover to protect it from dust and debris.

6. Fonctionnement de base
This section outlines the fundamental steps for observing specimens with your microscope.
- Mise sous tension : Flip the power switch located on the base of the microscope. The illuminator should light up.
- Ajuster l'éclairage : Use the variable intensity control knob to set the desired brightness. Adjust the iris diaphragm on the Abbe condenser to optimize contrast and resolution for your specimen.
- Spécimen de l'emplacement : Rotate the revolving nosepiece to select the lowest power objective (4x). Lower the mechanical stage using the coarse focus knob. Place a prepared specimen slide onto the mechanical stage et fixez-le avec le staget des clips.
- Position Specimen: Utilisez les XYtage control knobs to move the slide until the area of interest is centered under the objective lens.
- Mise au point :
- While looking through the eyepiece, slowly raise the stage en utilisant le molette de mise au point grossière until the specimen comes into rough focus.
- Utilisez le molette de mise au point fine to achieve a sharp, clear image.
- Modifier le grossissement : Once focused at low power, rotate the revolving nosepiece to switch to a higher power objective (e.g., 10x, 40xS). Due to the parfocal design, only minor adjustments with the fine focus knob should be needed to bring the image back into sharp focus.
- Utilisation de l'objectif à immersion dans l'huile 100xS :
- Après avoir effectué la mise au point avec l'objectif 40xS, faites pivoter le porte-objectifs à mi-chemin entre les objectifs 40xS et 100xS.
- Place a small drop of immersion oil directly onto the center of the specimen slide where the light passes through.
- Carefully rotate the 100xS objective into the oil drop until it clicks into place. The objective should be immersed in the oil.
- Utilisez uniquement le molette de mise au point fine to bring the image into sharp focus. Do not use the coarse focus knob with the 100xS objective.
- After use, clean the 100xS objective and the slide immediately with lens paper moistened with lens cleaning solution to remove all immersion oil.
- Double-View Fonctionnalité: The vertical port on the monocular head can accept a second eyepiece for simultaneous viewing by another person or a camera mount for digital image capture (eyepiece and camera sold separately). Dioptric adjustment on the upright tube accommodates individual eye-strength differences.

7. Maintenance et entretien
Proper maintenance ensures the longevity and optimal performance of your microscope.
- Nettoyage des lentilles : Use only specialized lens paper and lens cleaning solution for optical surfaces. Gently wipe in a circular motion. Never use abrasive cloths or harsh chemicals.
- Nettoyage général : Essuyez le corps du microscope avec un chiffon doux et sec.amp cloth. Avoid getting moisture into electrical components.
- Stockage: Always cover the microscope with the dust cover when not in use. Store it in a dry, dust-free environment.
- Remplacement de l'ampoule : If the illuminator bulb burns out, unplug the microscope. Refer to the base of the microscope for access to the bulb compartment. Carefully replace the old bulb with the provided spare bulb, ensuring not to touch the glass part of the new bulb with bare hands.
- Pièces mécaniques : Do not attempt to lubricate or disassemble any mechanical parts. If issues arise, contact customer support.
