Put Slide by One Hand. It is easy for users to put slides by one hand due to the special designed slide clip.
Tilting Trinocular Head. (1) The eye tube can be adjusted from 0°-35°. (2) Digital cameras or DSLR cameras can be connected to the trinocular tube. (3) The beam splitter has 3-position (100:0, 20:80, 0:100). (4) The splitter bar can be assembled on the either side according to user’s requirements. 
Image Capture Button. This is a cable from the microscope, the cable could be connected to the digital camera, after connection, just press the “CAPTURE” button at the right side of the microscope base, then you could capture the image easily. Low-Position Focusing System. Very precise coaxial focusing system with fine division of 1μm, it comes with low-position coarse and fine focusing knobs, the ergonomic design provides comfortable experience for users.
Motorized Objective Change. Objectives could be switched by simply pressing the buttons. Users could also self-define two of the most commonly used objectives and switch between them with the green button. The illumination has connection with the objective, when the objective is changed, the light intensity will also be changed accordingly.
