Magnification up to 640x
Microscope magnification depends on the objective lens and eyepiece lens magnifications. The eyepiece is the upper part of the tube of the microscope that you look into. The objective is located below and creates the image you see in the eyepiece. One WF16x eyepiece and three objectives (4x, 10x and 40x) are included in the package.
Observing non-transparent objects
The Levenhuk 3L NG Microscope, unlike other teaching microscopes, is equipped with two built-in illuminations. Both illuminations are LED, which ensures minimal energy consumption while providing sufficient light. Illumination systems are located above and below the stage, and allow observing both transparent and opaque objects: from tiny solid particles to coins, paper, fabrics, etc.
The microscope features an AC adapter, for stationary observations without batteries.
Caution: Please refer to the specifications table for the correct mains voltage and never attempt to plug a 110V device into 220V outlet and vice versa without using a converter. Remember that mains voltage in the U.S. and Canada is 110V and 220-240V in most European countries.

- Monocular head
- Objectives: 4x, 10x and 40x
- Eyepiece: WF16x
- Stage with clips
- Diaphragm disk
- Built-in upper and lower LED illuminations

Does this microscope have a 10x wide field lens? Levenhuk Customer Service:
Hi, Thanks for the query. The Levenhuk 3L NG Microscope comes with the following objective lenses: 4x, 10x and 40x.
I don't understand how to use 40x eyepiece. It's always dark when looking through the eyepiece. What could be the problem? Levenhuk Customer Service:
You can find the detailed instructions in the user manual. At the highest increase you can observe transparent thin slices. Change magnification power gradually from low to high. Smoothly adjust focus every time you change magnification power.
Hello! I bought this microscope as a new year gift for my son. I have a few questions to ask: 1. does the kit include cover slips? We didn't find them in the package... 2. how to observe at 640 x? we tried to adjust focus but it didn't work, couldn't see anything... 3. one more thing. the eyepiece was disassembled when delivered, we somehow managed to assemble it but we also scratched the glass, and now those scratches can be seen when observing... can I buy those glasses separately (for 16x eyepiece)? thank you! Levenhuk Customer Service:
1. Cover slips are not included in the kit. You can buy the separately here - https://www.levenhuk.com/catalogue/accessories/levenhuk-g100-cover-slips/. 2. You need to start with low magnification power, then switch to a more powerful objective and smoothly adjust focus. 3. Eyepieces are delivered assembled. We don't sell those glasses separately.
Hello, if I buy this scope, can I also purchase a case for it? Levenhuk Customer Service:
Unfortunately, microscope cases are not available in our store. Please consider Levenhuk 50L NG Microscope - https://www.levenhuk.com/catalogue/microscopes/levenhuk-50l-ng/
does this microscope have spring-loaded objectives? Levenhuk Customer Service:
Yes, Levenhuk 3L NG model is equipped with spring-loaded 40x objective lens.
would this be good choice for a 14 yr old high school student? if not, what would you recommend Levenhuk Customer Service:
Hi Olen, Thanks for the query. The 3L NG microscope would be a good choice, but I'd rather recommend to go for a more powerful 50L NG microscope which allows observing much smaller objects. Additionally, the 50L NG model comes with two eyepieces, a Barlow lens and a carrying case plus you can choose from several amazing colors. You may find more information here at https://www.levenhuk.com/catalogue/microscopes/levenhuk-50l-ng/. Is there any additional information you might need?
guys, the microscope is great! the kit is just awesome! yesterday we saw rotifers! But it seems there's a mistake in the product description - I didn't get a cover, which I don't need anyways... and amateur microscope model isn't supposed to have a condenser, am I right? Levenhuk Customer Service:
Levenhuk 3L NG Microscope comes with both dust cover and condenser. The dust cover is packed in a small transparent bag. The condenser is located between the stage and the illuminator. Amateur and educational microscopes are usually equipped with fixed and non-removable condenser.
Is this microscope good for viewing cells and tissues? Levenhuk Customer Service:
Yes, the Levenhuk 3L NG microscope allows you to observe cells and tissues.
we can't seem to study liquids under 40x, objective lens practically immerses into the water Levenhuk Customer Service:
You don't have to immerse the objective into the liquid when observing with Levenhuk 3L NG. Besides, you can't observe transparent liquids without staining. Please refer to this article for more information: https://www.levenhuk.com/reviews/slides-preparation/
Is it possible to observe blood cells, bacteria and tissues with this microscope? Levenhuk Customer Service:
Levenhuk 3L NG Microscope is not suitable for these purposes. We recommend that you consider Levenhuk 320 Biological Microscope (https://www.levenhuk.com/catalogue/microscopes/levenhuk-320/) - perfect instrument for blood examination, observing bacteria, as well as various tissues.
What is the numerical aperture of provided objectives? Levenhuk Customer Service:
Levenhuk 3L NG Microscope comes with the following objectives: 4x - 0.1; 10x - 0.25; 40x - 0.65.
Thank you, Levenhuk, for such a great microscope! Illuminations are very convenient. And the fastest delivery! Levenhuk Customer Service:
Thank you for your feedback on Levenhuk 3L NG Microscope.
Is this a good microscope for a 5 year old who is interested in all things science? Levenhuk Customer Service:
Dear Bethany, thank you for interest in Levenhuk products. Yes, it is a perfect choice! This microscope comes with an advanced kit. In any case, the microscope should be used with an adult present. Is there any additional information you might need?
Hello! I need your advice... I've heard that when observing microscope samples with large objectives, the top lighting gets in the way (when rotating) isn't it so? Maybe I should consider another model? Let's say... Levenhuk 50L NG? Thank you! Levenhuk Customer Service:
No, the upper illumination of the Levenhuk 3L NG microscope won't get in the way. We recommend that you consider the Levenhuk 50L NG model as it provides higher magnification power.
How does this model differ from Levenhuk 2L NG? Levenhuk Customer Service:
These models are similar. The only difference between them is that Levenhuk 3L NG Microscope comes with the Levenhuk K50 experiment kit and a dust cover.
Can I observe infusorians and other microorganisms? Levenhuk Customer Service:
Yes, the Levenhuk 3L NG microscope allows you to observe infusorians and many other microorganisms.
Can I see blood cells through this microscope? Levenhuk Customer Service:
You can't study blood composition with Levenhuk 3L NG Microscope. For detailed study of blood components we recommend Levenhuk D320L Digital Biological Microscope - https://www.levenhuk.com/catalogue/microscopes/levenhuk-d320l/.
Hello! Can I examine blood samples to study its composition (hemoglobin, white blood cells, red blood cells, etc.)? Levenhuk Customer Service:
To see the components of blood in detail, a microscope has to provide at least 1500x increase. To examine blood cells we would recommend using Levenhuk D320L Digital Biological Microscope - https://www.levenhuk.com/catalogue/microscopes/levenhuk-d320l/
what is the difference between bright-field and dark-field methods? Levenhuk Customer Service:
Bright-field microscopy is a technique that is used for observing transparent samples with light-absorbing particles. For example, thin stained slices of animal and plant tissues, minerals in thin-section, and so on. Dark field method is used in biology to observe transparent non-absorbing objects invisible in bright field, such as for example bacteria.
What's the difference between binocular and monocular microscopes?? Levenhuk Customer Service:
A binocular microscope has two eyepieces (one for each eye); a monocular microscope - one eyepiece only.
I am reading ""Attractive Microscope. Scrutinizing the Microcosm"" User Guide and I have couple of questions: 1. I've read that I can make a 'hanging drop' using special slide with a hole. But such slide is not included in the kit. What can I do about it? 2. it says that it's possible to use a drop of resin under high magnifications (how will I clean it off afterwards?) I thought that only immersion oil can be used and only with immersion objectives under very large increases, am I wrong? Levenhuk Customer Service:
In the 'Attractive Microscope. Scrutinizing the Microcosm""' User Guide there's no mention of this slide being included in the kit. You can always purchase microscope slides separately. A drop of resin is used to paste cover slips and slides together, it has nothing to do with immersion technique.
Hello! Is it possible to use a video eyepiece with 3L NG, 2L NG microscopes? Which video eyepieces are suitable? I mean, can I view images on a PC monitor? Record videos? Levenhuk Customer Service:
Levenhuk 3L NG is a better choice due to its extensive kit that includes large number of valuable accessories. You can attach a special digital camera that you can choose here: https://www.levenhuk.com/catalogue/digital-cameras/for-microscopes/
Hello! Is it possible to observe blood cells with this microscope model? Can I see images on my PC monitor? Levenhuk Customer Service:
Digital camera is not included in the kit of the Levenhuk 3L NG microscope. To study blood cells please consider Levenhuk D320L Digital Biological Microscope - https://www.levenhuk.com/catalogue/microscopes/levenhuk-d320l/
Is it in a foam package? Or just a box? Levenhuk Customer Service:
Yes, Levenhuk 3L NG is in the foam package inside the box.

Excellent microscope! Bought it and now we literally can't drag the kid away from it:) Thank you! Levenhuk Customer Service:
Thank you for your feedback!
Good day! A child (10 y/o) is interested in microscopes. Does it make sense to pay extra money for the Levenhuk 50L NG, or will the 3L NG be enough for the kid? Having compared these two models, I see that the main difference is the magnification. What interesting things can't be seen with 3L NG, but visible with 50L NG? Thanks for answering. Levenhuk Customer Service:
It does make sense: Levenhuk 50L NG Microscope features carrying case included in the kit, sturdier body material, higher magnification, retractable light source. You can observe the same objects, but with Levenhuk 50L NG Microscope you will see them at higher magnification.
What accessories do I need to work with it?
Can it be connected to a PC? Levenhuk Customer Service:
Microscope digital camera is required for connecting this microscope to PC: https://www.levenhuk.com/catalogue/digital-cameras-microscope-all-items/
