Product Description

Features a Siedentopf binocular head that rotates 360 degrees for shared use and allows quick adjustments for different interpupillary distances without losing focus. The head can be locked in any position for additional stability. Ocular tubes are tilted at an ergonomic 30 degrees to reduce neck and eye strain.

The microscope comes with two pairs of interchangeable 10X and 25X glass ocular eyepieces, which combine with the four achromatic DIN objectives -- 4X, 10X, 40X(Spring), and 100X(Spring, Oil) -- in the rotating nosepiece to provide 6 magnification levels between 40X and 2500X.

The focusing system of the SW380B truly shines, with an ultra-precise fine focusing knob that allows incredibly exact adjustments for the clearest possible image at each magnification. An LED bulb beneath the stage transmits light up through an industry-standard NA 1.25 Abbe condenser and iris diaphragm.

Manually move the condenser closer to or farther from the stage to adjust brightness and evenness of light as well as image contrast. A metal slide holder locks specimens into place for viewing on the sizeable double-layered mechanical stage while the x-y translational control knob moves the stage and the slide holder left-to-right and front-to-back, eliminating the need to re-clip slides in order to view the entire specimen.

Easy to move, with a built-in handle that fits securely against the palm. The power supply is built directly into the microscope base. The kit comes with a power cord, blue filter, immersion oil, and dust cover.

Assembly and set up
Carefully remove the microscope body from the box and set it on a sturdy, flat surface. Remove the microscope head from the box and secure it to the body with the head locking screw, using care not to overtighten.

Remove the plastic covers from the eyepiece holders on the microscope's head, then place eyepieces into the holders. You may choose at this time to insert the eyepiece adapter into the trinocular camera port on the top of the microscope and place either a third eyepiece into it or mount an eyepiece camera (not included). Locate the power adapter and attach it to the microscope, then plug it in. Turn the microscope on by pressing the power button on the back of the base.


Using the microscope
Turn the microscope on and use the illumination intensity control wheel to set the lamp on the lowest brightness setting.

Clip a slide into the slide holder on the stage. Use the X-Y translational control knobs on the right side of the stage to move the stage front to back or the slide holder left to right to center the specimen over the bulb.

Move the binocular eyepieces closer together or further apart until you see one image when you look through them. Adjust the bulb brightness to a comfortable intensity with the dimmer wheel. Note that another user can view the image simultaneously through using an eyepiece with the trinocular port.

Always start with the lowest power objective lens, in this case the 4X objective, centered over the stage. Look through the eyepieces and bring the image into focus by slowly turning the larger coarse adjustment focus knob to bring the stage closer to the objective. Once an image forms, switch to the blue fine adjustment focus knob to fine- tune for clarity or to see the various layers of the specimen you are examining. You may also use the diopter adjustment control on the eyepiece holder at this time to further
fine-tune image clarity. Look at other parts of the slide by using the X-Y translational control knobs to move the slide holder once the specimen is in focus.

Increase magnification by rotating the nosepiece clockwise to a higher magnification objective, taking care not to strike the slide with the objective as doing so may damage the glass on the slide, the objective, or both. If you cannot move the objective into place without making contact with the slide, use the coarse focus knob to move the stage down and away to make room before changing magnification.

Adjust the focusing ring on the iris aperture diaphragm to change the resolution of the image. The condenser can be manually moved closer to or farther from the stage by rotating the metal knob.

For best results with the 100X objective, use the included immersion oil. Rotate the nosepiece so that the 100X objective is near, but not on the specimen slide. Then place a drop of the included immersion oil onto the cover slip. Slowly rotate the 100X objective into place so that it comes into contact with the immersion oil. Adjust focus until your specimen comes clearly into view. (Note: Immediately after use, always gently wipe the oil off of the objective lens and the cover slip with lens paper moistened with a small amount of ethyl or isopropyl alcohol. Do not use immersion oil with the 4X, 10X, or 40X objectives.)

The swing-in and swing-out filter holder is at the bottom of Abbe condenser. Swing it out and place a 32mm diameter filter into it, taking care that dust, dirt and fingerprints do not get on the filter and the field lens.
