Compound Biological Microscope Magnification: 4 objective lens in metal barrels ( 4X,10X,40X,100X) built with multi-coated highly transparent optical glass with WF10X and WF20X(55 to 75mm interpupillary distance),which provide 8 magnifications between 40X and 2000X for biological and educational application.30°inclination with 360°rotation capability provides a more comprehensive view and enable sharing.Cedar wood oil can increase the resolution of the oil lens and improve observation effect.
Professional Metal Microscope Construction: Double Layer Mechanical stage with scales locks slide into place and provides precise slide manipulation along the X- and Y-axis to 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. Mechanical components and frame are constructed of metal for precision and durability.
Brightfield and Better Observation: Powerful LED illumination with adjustable brightness,which provides bright, cool light for working with temperature-sensitive or live specimens. N.A=1.25 Abbe condenser and Iris diaphragm provide better lighting conditions and brighter field to illuminate specimens. Coaxial coarse & fine focus knobs on both sides is adjustable for sharp images.
Good Use Experience: Compound light microscope with a sucker phone adapter, it can record beauty,acquire knowledge in the micro world and cultivate students’ love of natural science.Microscope slides leads you to explore the fantastic tiny things. Blue filter can be used in different levels of light control to observe.
2 Kinds of Power Supplies: The microscope is powered by a power adapter (100 to 240V) or 3 AA batteries(not included) for different usage situationYou needn’t worry there is no electrical socket outlet outside and can use batteries instead..It’s an excellent microscope for students,adults and professional biological hobbyists to learn sciences.
ESSLNB 40X-2000X Biological Monocular Microscope
with X-Y Axis Double Layer Mechanical Stage NA1.25 Abbe Condenser Oil Immersion Slides and Phone Adapter
Compound biological microscope comes with eight magnifications from 40X to 2000X. It comes with a 30° inclined binoculars viewing head, two pairs of widefield eyepieces (WF10X, WF20X), four Din achromatic objectives 4X, 10X, 40X(S), 100X(S, Oil), large X-Y Axis double layer mechanical stage with scales, NA1.25 Abbe condenser with iris diaphragm, coaxial coarse & fine focus knobs and variable intensity LED transmitted illumination system.
With biological slides and blank glass slides, coverslips and blue filter, accessories are necessary.Cedar wood oil is used for 100X oil immersion objective.
With a sucker phone adapter, it can record beauty,acquire knowledge in the micro world and cultivate students’ love of natural science.
Solid Material—All Metal Mechanical Components and Frame with Stain Resistant Finish
High Quality Optics— Fully Coated Precise Optical Glass Elements
8 Magnification Settings—40X, 80X,100X, 200X, 400X, 800X,1000X ,2000X
55 to 75mm interpupillary distance gives you better observation based on your pupil distance.
Equipped with four 195 all-optical achromatic objectives, the body is made of metal copper, the multiples are 4x, 10x, 40x, 100x. Since the 40x and 100x objective lenses are close to the slides during observation, the two lenses are internally designed with springs in order to prevent crushing of specimens.
A single objective lens structure accessories are extremely complicated, the accessories are metal parts, copper parts, optical parts.
A conjugate distance of our objective lens is 195 mm,which is an achromatic objective lens that corrects field curvature and astigmatism and a vertical axis chromatic aberration of less than 2.5%.
2000X Magnification with 100X Oil Immersion Objective
195 Achromatic objective lens offer larger lens, better optical system, higher cost,more light transmission and clearer image
The instinctive reaction of a first time user is to prefer microscope kits that offer higher magnification. But this is misleading. Most microscope kits don’t offer any intermediate magnifications between 1000X and the maximum magnification they offer (2000X or 2500X), so that maximum magnification doesn’t really give you any extra resolution over a 2000X microscope.
Large Field of Eyepieces
A pair of wide-field eyepieces (WF10X/20X) provides 8 magnifications between 40X and 2000X for biological use and educational application.
Two wide-angle eyepieces is made of full-optical glass lens, with metallic lens body.
It gives you clear imaging effect and excellent workmanship feeling.
NA1.25 Abbe Condenser with Iris Diaphragm
The light intensity can be controlled with the aperture lever to control the amount of light focused on an object or organism.
Abbe ondenser can move up and down by rotating the condenser lifting control ring to change the light intensity.
Blue filters can increase the resolution of the objective lens, weaken the intensity of the light source, and maximize the aberration.
Coaxial Coarse and Fine Focus Adjustment
It offers precise location for sharp and clear images.
Coaxial coarse & fine focus knobs on both sides
The coaxial positioning makes you not to move your hand much when focusing the microscope.
Mechanical stage with adjustment handle
The double layer mechanical stage gives you full movement of your sample for scanning purposes, or centering purposes.
Instead of just the clips moving around on the stage, the entire stage moves in the X, Y, and Z dimensions.
Your slide won’t slip off in any way when you’re trying to locate your point of interest on your slide.
Binoculars Biological Microscope
Microscopes are widely used in education, lab research, biology, metallurgy, engineering, chemistry, manufacturing, and in the medical, forensic science, and veterinary industries.
