4. Komponentidentifikation

Familiarize yourself with the various parts of the Ken-A-Vision T-29033 Research Microscope:

Figur 1: Ken-A-Vision T-29033 Research Microscope. This image displays the complete microscope from a front-right perspective, showing the binocular eyepieces, revolving nosepiece with objective lenses, mechanical stage, and focusing knobs on the side.

1. Okularer: 10x 20mm, with eyeglass guards and variable adjustment for eye strengths.
2. Binocular Head: 30-degree incline, 360-degree rotation.
3. Revolving Nosepiece: Holds the objective lenses.
4. Objektive linser: 4x, 10x, 40xS, 100xS DIN plan objectives.
5. Mekanisk Stage: 180mm x 150mm, with scratch-resistant coating and vernier scales for precise specimen movement.
6. Kondensator: N.A. 1.25, with rack and pinion adjustment, filter holder.
7. Coaxial Coarse and Fine Focus Knobs: For adjusting focus.
8. Belysningssystem: Halogen tungsten bulb (12V 20W) with variable brightness, Kohler illumination.
9. Grundlag: Stable aluminum single cast body.

5. Opsætning

1. Udpakning: Carefully remove the microscope and all accessories from the packaging. Retain the original packaging for future transport or storage.
2. Placering: Place the microscope on a stable, level surface, away from direct sunlight, heat sources, and vibrations.
3. Head Installation: If the binocular head is separate, gently insert it into the top of the microscope body and secure it with the exposed thumb screw.
4. Eyepiece Insertion: Insert the two 10x 20mm eyepieces into the eyepiece tubes of the binocular head.
5. Strømtilslutning: Connect the power cord to the microscope's power input and then to a grounded electrical outlet (AC 85V - 240V).

6. Betjeningsvejledning

1. Tænd: Flip the power switch located on the base of the microscope. Adjust the illumination intensity using the variable brightness control knob.
2. Prøveplacering: Place a prepared microscope slide onto the mechanical stage. Brug stage clips to hold it securely.
3. Stage-bevægelse: Brug XY stage control knobs to position the specimen directly under the objective lens.
4. Målsætningsvalg: Rotate the revolving nosepiece to select the lowest power objective (e.g., 4x). Ensure the objective clicks firmly into place.
5. Fokusering:
   • Look through the eyepieces.
   • Brug coarse focus knob to bring the specimen into approximate focus.
   • Brug fine focus knob for precise focusing and to achieve a sharp image.
6. Justering af pupilafstand: Adjust the distance between the eyepieces by gently pushing or pulling them apart until you see a single, circular field of view.
7. Dioptrijustering: If one eye is clearer than the other, use the diopter adjustment ring on one eyepiece to compensate for differences in vision.
8. Higher Magnification: Once focused at low power, rotate the nosepiece to a higher power objective (e.g., 10x, 40xS). The microscope is parfocal, meaning only minor adjustments with the fine focus knob should be needed.
9. Using the 100xS Oil Immersion Objective:
   • After focusing with the 40xS objective, rotate the nosepiece halfway between the 40xS and 100xS objectives.
   • Place a small drop of immersion oil directly onto the specimen slide where the light passes through.
   • Rotate the 100xS objective into the oil drop. The objective should be immersed in the oil.
   • Use only the fine focus knob 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 and a suitable lens cleaning solution to remove all immersion oil.
10. Condenser and Iris Diaphragm Adjustment: Adjust the condenser height and the iris diaphragm to optimize contrast and resolution for each objective. Generally, higher magnification requires more light and a wider diaphragm opening.

7. Vedligeholdelse

• Rengøring af optik: Use only specialized lens paper and lens cleaning solution for objective lenses and eyepieces. Gently wipe in a circular motion. Never touch optical surfaces with bare fingers.
• Rengøring af krop: Tør mikroskophuset af med en blød kludamp klæde. Undgå at bruge skrappe kemikalier eller opløsningsmidler.
• Støvbeskyttelse: Always cover the microscope with the provided dust cover when not in use.
• Opbevaring: Store the microscope in a cool, dry, and dust-free environment. Ensure the lowest power objective is in place and the stage is lowered.
• Udskiftning af pære: If the halogen bulb burns out, unplug the microscope and allow it to cool. Refer to the diagram in the bulb compartment for replacement instructions. Use only the specified 12V 20W halogen bulb.
