The Cordless Microscope with Three Objectives - National Optical 211-RLEDfrom Cordless Microscope with Three Objectives - National Optical 211-RLEDis a three-objective single viewing microscope with a 45° inclined monocular. The three objectives are located on rotating turret with a ball bearing mount. The turret has four holes and can accommodate a fourth objective. Both the turret and the included objectives adhere to the DIN microscope objective standard. Therefore, you can use any commercially available DIN objective with this microscope.

The supplied objectives have achromatic lenses which reduce color distortions introduced by imperfections in optical elements. Reducing these color distortions allows you to see sharper images and true colors. The parfocalled and parcentered design allows for switching objectives without having to realign your sample and without losing focus. The microscope also features a wide field 10x eyepiece and has a fine and a coarse focus adjustment.

The LED illumination system has adjustable brightness which is controlled by a rheostat. It delivers light intensity equivalent to that of a 20W incandescent bulb. The light from the bottom LED emitter is focused on the sample with a 1.25 NA Abbe condenser.

The 5.3 x 5.3" mechanical stage has adjustable height, a movable slide holder and allows you to move specimen slides in X-Y plane. The slide holder bracket holds your slides securely in place. The frame of the microscope is made of cast metal with gray enamel finish.

Included with the microscope are three rechargeable AA NiMH batteries, battery charger, a dustcover, and two Allen wrenches for rack stop adjustment and eyepiece socket tension adjustment.

          A: You may calculate your actual shipping options/order totals by adding the items you want to a shopping cart. It will then list the shipping options, descriptions, ETA's and fees to your location. Unfortunately there is nothing we can do to reduce the international shipping fees you see listed on our website for any product. We understand that sometimes we may not be the most prudent choice to shop with in regards to shipping a single small item overseas. The rates posted on our site are the rates posed to us by the respective carriers we use. You may wish to wait until you have a larger order to place so that the shipping cost would be absorbed, or try to get a few colleagues to place a single order together so that the shipping costs would then be absorbed.
