About the Digital Microscope
Your new digital microscope incorporates a built-in camera that uses data transmission made possible through a simple plug and
play USB cable. In order to achieve optimum results, it is important that you carefully read this manual before operating your
microscope. Instructions for software are located on Motic Images CD.
UNPACKING
1. Your microscope is packed with the following components, all of which have been checked at the factory. Carefully remove all
components and check against this list.
A. Microscope, with WF10x eyepiece, four objective lenses, and 1.25 N.A. Abbe condenser.
B. Specimen holder
C. CD Motic Images software for PC and Mac
D. Calibration slide
E. USB cable (for connecting to computer)
F. Automatic switching recharger operates on 100 to 240 volts AC 50/60 Hz.
G. 0.9mm “L” type hex key wrench (for replacing LED lamp).
H. Dustcover
2.
Retain styrofoam container in case microscope must be transported or returned to factory for any reason.
If it
becomes necessary to ship the microscope for any reason, repack 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. LED INDICATOR LIGHT: Indicates if camera is on. LED light becomes illuminated after software commands turn camera ON.
2. EYEPIECE (ocular lens): Lens closest to the eye, magnifies the primary image formed by the objective lens.
3. OBJECTIVE TURRET (nosepiece): Revolving turret which holds objective lenses, permits changes of magnification by
rotating different powered objective lenses into optical path.
4. OBJECTIVE LENS: Lens closest to the object being viewed, forms first magnified image of the specimen.
5. SPECIMEN HOLDER: Holds specimen slide.
6. STAGE: Platform of the microscope where the specimen slide is placed.
7. CONDENSER: A 1.25 N. A. Abbe condenser lens positioned under center of stage, condenses light rays from substage
illumination and fills the back lens element of objective lens to improve image resolution.
8. IRIS DIAPHRAGM: Attached to bottom of Abbe condenser, controls aperture of light by moving control lever left or right.
9. FILTER HOLDER: Swing out filter holder with special neutral filter built in.
10. ON/OFF SWITCH: Main power switch for microscope LED Illuminator.
11. LIGHT HOUSE: Built-in substage 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 electric cord are needed.
12. RHEOSTAT INTENSITY CONTROL: Controls the intensity of the LED illuminator.
13. 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.
14. MECHANICAL STAGE: Permits precise mechanical manipulation of the specimen slide.
