B120 Siedentopf Binocular Compound Microscope, 40X-1000X Magnification, Brightfield, LED Illumination, Abbe Condenser, Double-Layer Mechanical Stage

This compound microscope delivers high magnification for biological and educational purposes. It includes a Siedentopf binocular head with a set of 10x widefield eyepieces providing 53 to 77mm inter-pupillary adjustment. The head has a fixed 30-degree vertical inclination to minimize eye and neck fatigue, as well as 360-degree rotation functionality for a broader view and convenient sharing. The forward-facing nosepiece is fitted with 4x, 10x, 40xS (spring), and 100xS (spring, oil) DIN achromatic objectives that ensure color correction for magnified images. Illumination comes from a brightfield LED system, combined with a 1.25 NA Abbe condenser equipped with an iris diaphragm for clear observation and accurate light control. A double-layer mechanical stage with 1.0mm divisions firmly secures slides in position. It permits exact manipulation along the X- and Y-axis, allowing coordinates to be noted so the user can revisit a particular location on the slide
