[. . . ] Rotate the knurled locking nut downward to lock the safety screw in place. 6 Focusing: Now that the specimen slide is placed directly under the objective lens, use the course focus knob (12) to focus on the specimen. · Always start with the lowest power (4x objective lens) and switch to higher power by rotating the objective lens rotator (3). Be cautious not to let the objective lens touch the specimen slide when changing to higher power. · Use the fine focus knob (10) to change the depth of field on the specimen you are observing. · If you run out of upward travel before reaching sharp focus, you can unscrew the focus travel safety screw (14) to allow for more upward travel. Once again be careful not to let the objective lens touch the specimen slide. Replacing the illuminator lamp: 1. Raise the specimen stage (6) to its highest position by rotating the course focus adjustment knob (12). Unscrew the black metal illuminator housing (8) and lift it straight up over the lightbulb. Turn the lightbulb counterclockwise while gently pushing down. Slide the illuminator housing back over the lightbulb and thread into place. 7 Research Microscope ­ Model #4060 115 1 2 3 21 20 19 18 17 16 15 14 4 5 6 7 8 9 10 13 12 11 Figure 3 1 2 3 4 5 6 7 8 9 10 11 Eyepiece Eyepiece Diopter Eyepiece Housing Locking Screw Stand Column Specimen Holder Focuser Lock Coarse Focus Handwheel Fine Focus Handwheel Transverse Specimen Mover Handwheel Brightness Control Wheel 12 13 14 15 16 17 18 19 20 21 Longitudal Specimen Mover Handwheel Power Switch Illuminator Condenser Adjustment Handwheel Iris Diaphragm Condenser Specimen Stage Specimen Holder Clamp Lever Objective Objective Changer Standard Accessories Your Celestron microscope (#4060) comes complete with the following standard accessories: · · · · · Two 10x Eyepieces Two 15x Eyepieces One 4x Objective lens One 10x Objective lens One 40x Objective lens · · · · One 100x Objective lens Three Color Filters (Red, Blue , Green) Plastic Dust Cover Cedar Wood Oil 8 Item #4060 Optical Head Interpupillary distance Illuminator Stage Size Working Range Condenser Power Supply Nosepiece Objectives Specifications: 45º inclined Binocular Head; 360º Rotatable Adjustable from 55-75mm Built-in, electric illuminator; Halogen bulb 6v/20w Built-in, Mechanical 123mm x 153mm 70mm x 40mm Abbe N.

Objective Lens 10x 100x 150x Eyepiece 4x 10x 15x 40x 60x 40x 400x 600x 100x 1000x 1500x Assembling Your Microscope Before you can view through your Celestron microscope, the eyepiece housing, eyepieces and objective lenses must first be attached. Remove the microscope body from its packaging by lifting it by the stand column (5). Unthread the locking screw (4) located on the side of the microscope body just above the objective lens changer (21). Place the round angled end of the eyepiece housing (3) inside the circular opening at the top of the microscope body. Use the knurled ring to rotate the objective lens changer (21) until the 4x objective lens is directly over the specimen (Always start with the lowest power objective and work you way up to higher powers). Look through the eyepieces while turning the coarse focus handwheel (8) until the specimen comes into view. You may need to adjust the specimen mover handwheels (10 & 12) slightly to center the specimen in the field of view. Warning: When focusing, be careful not to raise the specimen stage so high that the specimen slide touches the objective lens. Not only can you break your slide but you may also scratch the objective lens. Finally, adjust the fine focus handwheel (9) until you reach the sharpest focus for your eye. Never rotate both of the fine focus handwheels at the same time in opposite directions.
