The new BMS 037 LED is an ideal starter microscope for hobbyists. The microscope's stability is optimized by the robust stand's and bases' construction. Because of its cleverly placed handle in the stand the BMS 037 LED will move effortlessly wherever you need it to be. The enhanced LED illumination combines the advantages of an incident light type with a transmission type to a handy combined microscope. The transmitted and incident light are separately operable and are adjustable by a dimmer. This unit has a 10x wide field eye piece mounted at a 45 degree angle for comfort. The triple nosepiece features 4x, 10x, 40x objectives with a total magnification of 400x. The fixed condensor N.A. 0,65 is provided with a six aperture disc diaphragm to adjust the amount of light coming through the specimen slide. This BMS 037 LED may be a basic starter microscope but its optics are far better than you might expect from its low price. It is a very good value that will let you observe a hidden realm of detail and structure within everyday objects that is totally invisible to the unaided eye.
