Happybuy Trinocular Compound Microscope 40X-2500X Magnification Digital Compound Microscope WF10X & WF25X Eyepieces Compound Light Microscope LED Light Abbe Condenser Siedentopf Head, Mechanical Stage

  • Humanized Siedentopf Head: Should I solely choose one merit of this trinocular compound microscope to introduce, it will be the Siedentopf head. Two contributing factors behind my choice are its spectacular flexibility catering for varied inter-pupillary distances without any focus loss and 360-degree rotation capability for better sharing and collaboration. What's more, 10X and 25X optical glass eyepieces and 30-degree inclination of the head make your observation more comfy and easy..
  • Clear & Sharp Images: Look closer, and you can catch sight of our 4 DIN achromatic objectives (4X, 10X, 40XS, and 100XS, Oil) mounted in a revolving nosepiece. Thanks to that, as many as six magnification levels are provided for your choices, 40X, 100X, 250X, 400X, 1000X, and 2500X. Aside from multiple magnification options, the achromatic objectives can also perform color correction to present sharp and clear magnified images..
  • Precise Focus Adjustment: The double-layer mechanical stage plays a vital role in the process of focusing and calibration by its 1.0 mm scale divisions. With the help of coaxial coarse and fine knobs and X/Y axis (travel range: 2.76 x 1.18 in / 70 x 30 mm.), you can achieve the fast and precise adjustment of the slide. Moreover, the coordinates ....
