Byomic Stereo Microscope BYO-ST3LED

The Byomic Stereo Microscope BYO-ST3LED is an easy to use microscope and suitable for hobbyists but also for primary and secondary schools. This microscope has two non interchangeable fixed objectives with a magnification of 2x and 4x. With the wide angle eyepieces of 10x it is possible to switch between 20x and 40x magnification.


The BYO-ST3LED has a solid metal housing with an integrated table measuring 115 mm by 105 mm which is equipped with two solid clamps to hold a specimen in position, so it does not shift during observation. The table has a contrast plate of Ø95mm. This contrast plate is white on one side and black on the other side, so that certain specimens with a different contract can be observed.


Because the Byomic BYO-ST3LED is equipped with two wide-angle eyepieces, you have a large field of vision and excellent depth of field. Because the eyepieces have a viewing angle of 45 degrees, the microscope can be used in a relaxing position. The eye distance is adjustable between 54 and 76 mm and the dioptre of the left eyepiece can also be adjusted so that you can get the subject in sharp focus. The supplied Premium eyecups can be slid over the eyepieces so that you are not distracted from movements you observe around the eyepiece and it is easier to maintain the correct distance to the lens. By using these eyecups it is possible to fully focus on the subject which benefits the perception.


Because the Byomic BYO-ST3LED is equipped with both light and backlight illumination, the subject can be illuminated well with this microscope. Besides the supplied power adapter, the microscope can also be used with 3x AA batteries. This way the microscope can be used everywhere. also in places where there is not immediately a power outlet nearby. Besides the illuminant slide of Ø95mm, there is also a contrast plate of Ø95mm included in the color black and white, so you can also work with contrast.
