🔬 ESSLNB 40X-2000X Biological Compound Microscope with Phone Adaptor and Slides, N.A = 1.25 Abbe Condenser, LED Lab Microscopes with X-Y Mechanical Stage – Ideal for Adults and Students Review

Four Achromatic DIN metal objectives combine with interchangeable wild field WF10X/20X eyepieces,which provide optimum magnification 40X-2000X for biological and educational application.All microscope lenses are fully-multi coated highly transparent all-optical glass and can give you a crystal clear image. 55 to 75mm adjustable pupil distance,30° inclination with 360°rotation provides a more comfortable and comprehensive view. Double-layer mechanical stage with scale and adjustable handle, includes full graduated X/Y movement, which allow coordinates to be recorded, enabling the viewer to return to a specific location on the slide.Convenient to move and locate the small piece and prevent jitter under high magnification.Ultra-Precise Coaxial coarse and fine focus buttons on both sides can be easily adjusted for sharp images. 3W LED Brightfield illumination allows the specimen to absorb light,resulting in a dark image on a light background.Lower brightfield illumination transmits light up through the specimen for enhanced visibility of translucent and transparent objects.N.A=1.25 Abbe condenser and Iris diaphragm provide good lighting conditions and brighter field to illuminate specimens. Compound binocular microscope with phone adapter, it can record beauty,acquire knowledge in the micro world and release your eyes from long-time observation.Microscope slides leads you to explore the fantastic tiny things. Blue filter can be used in different levels of light control to observe.Immersion oil can increase the resolution of the oil lens and improve observation effect. Solid metal construction ensures stability. The microscope can be powered by a power adapter (100 to 240V) or 3 AA batteries(not included) for different usage situation.It's a professional biological compound microscope to observe things in details, excellent for clinical, laboratory, and educational use, like high school and university science students microscope.
