COMPOUND MICROSCOPES

National Optical & Scientific Instrument Inc.

For optimum viewing satisfaction, follow these simple procedures. Nomenclature used to describe components and

controls can be identified by referring to the diagram at left.

UNPACKING

1. Carefully remove microscope, dustcover, 0.9mm L hex key wrench, “C” wrench for tension adjustment and recharger.

Always handle and move microscope by securely holding the arm of microscope. Avoid touching any of the lens

surfaces while handling the microscope. Dust, dirt, or fingerprints can damage the delicate lens surfaces or adversely

affect image quality.

2. Examine packing material before you discard it. Retain the styrofoam container in case you need to transport, store,

or return the microscope for service. If it becomes necessary to ship the microscope for any reason, pack it in the

styrofoam container, and then pack the styrofoam in another corrugated shipping container for optimum protection.

Use of the styrofoam alone will not provide adequate protection in transit, and will void your warranty.

DESCRIPTION OF COMPONENTS

1. EYEPIECE (ocular lens) Lens closest to the eye, magnifies the primary image formed by the objective lens. The

eyepiece is equipped with a “pointer” that rotates as the eyepiece is turned.

2. OBJECTIVE TURRET (nosepiece) Revolving turret which holds objective lenses, permits changes of magnification

by rotating different powered objective lenses into optical path.

3. OBJECTIVE LENS Lens closest to the object being viewed, forms first magnified image of the specimen.

4. STAGE CLIPS Two locked-on clips hold specimen slide in place on stage. Note: Your microscope is already drilled

and tapped to accept an optional mechanical stage. Mechanical stage replaces stage clips and permits precise,

mechanical manipulation of the specimen slide.

5. STAGE Platform of the microscope where the specimen slide is placed.

6. CONDENSER LENS A specially designed condenser lens, fixed in center of stage, condenses light rays from

substage illumination and fills the back lens element of objective lens to improve image resolution.

7. DISC DIAPHRAGM Rotating disc located below stage, with holes of various apertures, designed to help achieve

optimum resolution of the objective lens. Larger apertures used for higher magnifications, and smaller apertures used

for lower magnification.

8. SAFETY RACK STOP When properly adjusted, controls maximum upward travel of stage. Prevents higher power

objectives from breaking specimen slides, prevents damage to objective lenses. This stop has been pre-adjusted at

the factory.

9. FOCUSING KNOBS Coarse focusing knobs (larger knobs) located on each side of arm, raise or lower stage to

bring specimen image into focus. Fine focus knobs (smaller knobs located just below coarse focusing knobs) permit

more precise image adjustment.

10. ILLUMINATION Built-in substage electric LED illuminator provides constant, reliable, pre-focused illumination equal

to a 20-watt tungsten bulb. Powered by 3 rechargeable AA nickel metal hydride batteries, no power outlet or electrical

cord is needed.

OPERATION

1. Place microscope directly in front of you in a manner which permits you to comfortably look into the eyepiece. Note

that the head of microscope rotates 360º, permitting you to operate the microscope from the front or from the back,

whichever is most convenient for you. It also permits convenient sharing of microscope by more than one user, by

simply rotating head, without needing to move entire microscope. Most users will position the microscope with the

arm facing them so that focusing knobs are most convenient to reach.
