Using the Condenser
The condenser is furnished with an iris diaphragm, which has to be adjusted to match the effective numerical aperture of the individual objectives.
Selecting an Objective
1. Rotate the desired objective over the sample.
2. Rotate the condenser diaphragm below the specimen stage so that the displayed value matches the selected objective.
Leica DM300 User Manual 25
Preparing for Viewing
Preparation
1. Open the specimen holder using the tension lever.
2. Insert the specimen slide and slowly release the tension lever.
3. Using the X/Y control, position the specimen slide such that a part of the specimen is under the objective used.
Leica DM300 User Manual 26
Focusing
Focusing
1. Use the knurled ring to rotate the objective nosepiece in such a way that the objective with the lowest magnification level is turned into the working position.
2. Move the specimen stage upwards as far as it will go using the coarse adjustment knob.
3. Look into the eyepieces and adjust the illumination to a comfortable intensity.
4. Bring the specimen into focus using the fine adjustment knob.
Leica DM300 User Manual 27
Adjusting the Binocular Tubes
1. Adjust the tubes to your interpupillary distance. Fold or unfold the eyetubes to decrease or increase the distance between the eyepieces until you see one illuminated circle.
The viewing tubes maintain a constant tube length for all interpupillary settings.
This means that a change of interpupillary distance does not affect parfocality, magnification, or calibrations that depend on magnification.
Open Binocular Tube
If you are using an open standard tube, you need to make some adjustments.
1. Set the focusing eyetube (left side) to "0".
Leica EZ tubes
If you are using a Leica EZ viewing tube, which already has the eyepieces integrated with the eyetubes, no additional adjustments are necessary. Be sure you are wearing your eyeglasses or contact lenses.

Leica DM300 User Manual 28
Adjusting the Binocular Tubes (continued)
If you are comfortable wearing your corrective lenses (contact lenses or eyeglasses) for microscope viewing, leave them on and your adjustments will be minimal.
2. Bring the specimen into focus using 10× magnification and the fine adjustment knob while looking through only the right eyepiece. To help focus, cover or close your left eye.
3. Now look with your left eye through the left eyetube (focusing eyepiece). Now focus using the focus function of the eyetube.
When doing so, do not change the height of the specimen stage.
4. Rotate the knurled ring on the left eyetube, until the specimen is sharply focused for the left eye. This corrects for any vision differences between your right eye and left eye.
5. Now, switch to an objective with a higher magnification level (no oil objective) and bring the specimen into focus while looking through the eyepieces with both eyes.
The depth of field is lower for higher magnification levels. Thus, you will notice that if you switch to low magnification after bringing the microscope into focus with great magnification, a minor adjustment of the fine focus may be required. Continue with the
"Oil immersion" section on page 31.
Leica DM300 User Manual 29
Adjusting the Eyecups
If you wear eyeglasses for microscope viewing, keep the rubber eyecups folded down. If you do not wear eyeglasses, you may find it useful to unfold the rubber eyecups in order to help block out ambient room light.
Potential Sources of Infection
Direct contact with eyepieces is a potential transmission method for bacterial and viral infections of the eye. The risk can be minimized by the use of individual eyecups.
Eyecups can be ordered separately. Please contact your Leica partner.

Oil Immersion Technique
Oil Immersion Technique
1. Search for the area on the specimen slide that you want to study.
2. Move the specimen stage down to the lowest position using the coarse adjustment knob.
3. Add a drop of immersion oil from Leica to the area of the specimen slide you are studying.
5. Slowly move the specimen stage upwards using the coarse adjustment knob until the oil drop on the slide comes into direct contact with the lens of the oil immersion objective.
Leica DM300
4. Rotate the 100× objective to the working position.
6. Hold the knurled ring on the objective nosepiece and swing the objective back and forth to eliminate air bubbles. Then bring the oil objective into the final position, so that the oil drop is between the front lens of the objective and the specimen slide.
User Manual 31
Oil Immersion Technique (cont.)
7. Look through the microscope and slowly rotate the fine adjustment knob, so that the specimen stage moves upwards until the specimen is in focus.
8. If you are finished working with the oil immersion objective, clean the front side of the objective, the specimen slide, and all other surfaces that have come into contact with the oil, following the instructions in the "Care of the Microscope" section on

Leica DM300 User Manual 34
General Maintenance
General
Always use both hands to carry the microscope.
Ϙ
Ϙ
Ϙ
Keep all optical components clean. Cleanliness is important for maintaining good optical performance.
When the microscope is not in use, it should always be put away with protection against dust.
If any optical surface becomes coated with dust or dirt, clean the surface by blowing it off with a syringe or brushing it off with a camel hair brush before attempting to wipe the surface clean.
Ϙ
Ϙ
Optical surfaces should be cleaned using a lint-free cloth with a commercially available glass cleaner.
Use solvent only very sparingly, so that it does not flow out over the lens. No part of the microscope is quite so vulnerable to collecting dirt, dust, and oil as the front lens of the objective. Whenever you encounter lack of contrast, cloudiness or poor definition, carefully check the condition of the front lens with a magnifier.
Leica DM300 User Manual 35
General Maintenance (cont.)
Ϙ
Ϙ
The lower magnification objectives have fairly large front lenses and can be cleaned with a cloth or lens tissue wrapped around a finger and moistened with window cleaner.
Cleaning 40× and 100× objectives requires more care. To attain the typical flatness for objectives with higher magnification, the objective has a small concave front lens with a very small radius and slight curvature. The surface of this front lens can be readily cleaned with a toothpick covered with a cotton tip, or with a small cotton swab. Wipe the front lens lightly without applying undue force or scrubbing action.
Make sure that the cotton tip contacts the concave lens surface. Check the objective with a magnifier after cleaning.
Illumination
Ϙ
The Leica DM300 uses an LED illuminator.
Therefore, no lamp changing is required for the entire life of the microscope.
