The Byomic Stereo Microscope BYO-ST341 LED is a professional trinocular microscope with plan-achromatic objectives for faithful reproduction and reduction of chromatic abberation. The BYO-ST341 LED is used by advanced users for professional purposes. Because the microscope has two plan achromatic zoom lenses (adjustable from 0.75x - 5x), a magnification of 7.5 - 50x can be achieved with the two wide angle eyepieces of 10x. It is possible to adjust the dioptre for both eyes so that extremely sharp images can be obtained during observations. Illumination The lighting can be operated with the two switches. The switch on the left is to switch the backlight on or off. The switch on the right is for the illumination which can also be changed in brightness with the wheel on the front. This ensures that the sample always has the right amount of light. The maximum height is approximately 220 mm, measured between the table and the objective. Larger objects are also possible, because the microscope can be rotated 360°. In addition to the Ø95mm dialect slide, a Ø95mm contrast plate in black and white is also supplied, so that you can also work with contrast.
