Ideal for biological students and microscopy enthusiasts, the BRESSER Erudit Basic 40-400x Monocular Microscope is powered by three AA batteries that allow you to take it into the field for hours of on-the-ground research and comes with a universal smartphone adapter to capture photos and videos of your specimens through the eyepiece for documentation and sharing. Its monocular head is set at a comfortable 45° angle to the body for a natural and comfortable viewing position and can rotate a full 360° to make sharing the view among lab partners and colleagues simple and easy. It comes equipped with a 10x wide-field eyepiece that, when combined with the objectives, produces magnifications from 40x to 400x—making it ideal for viewing a wide variety of specimens, including thin sections, pond life, or skin and fur parasites.

Its dual-speed coaxial focuser features coarse and fine adjustments to ensure views are tack sharp. A large stage has integrated slide holders that can be used with one hand to make changing slides fast and a Vernier scale on the X and Y axes for measuring your specimens. The lower LED illuminator has a rheostat to control the intensity and is directed through a large 1.25 NA Abbe condenser with a simple iris diaphragm that gives you extreme control of the light coming through to the stage. The aperture of the condenser is larger than the highest-power objective, so you can be sure that the appropriate amount of light is transmitted to the specimen at all magnifications. Current LED technology delivers higher light efficiency than a conventional tungsten bulb with a cool operating temperature that prolongs specimen life when viewing live material and extends battery life when working in the field.
