The Levenhuk 40L NG teaching biological microscope.
This excellent biological microscope is ideal for use in schools or colleges as well as for your own research of the microworld.
- Superb production quality: body and elements are all-metal, not plastic.
- Focusing mechanism and stage move smoothly, without jerks or backlash.
- Rotatable head can be fixed in any position, which makes observation much more convenient.
- Eyepieces, objectives and all other optical elements are multi-coated and highly transparent.
All this provides extremely high image quality and long microscope life without any special maintenance.
Magnification depends on the objectives (located below) and eyepieces (located above) being used.
The set includes two eyepieces and three objectives as well as Barlow lens, which allows to smoothly change the magnification ratio.
- Eyepieces: WF10x, WF16x
- Objectives: 4x, 10x and 40x
- Barlow lens: 2x
Minimum magnification: Eyepiece 10x * Objective 4x = 40x
Maximum magnification: Eyepiece 16x * Objective 40x = 640x, and with Barlow lens magnification smoothly reaches 640*2.0 = 1280x!
This microscope is distinguished by an important feature - two illumination systems with adjustable brightness. Built-in illumination is LED, which ensures minimal energy consumption yet still 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. (It would be fascinating to observe a mobile phone screen - actually, each pixel consists of three segments, red, green and blue.)
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.
The kit includes:
- Objectives: 4x, 10x and 40x
- Two eyepieces: WF10x, WF16x
- 2x Barlow lens
- Stage with clips
- Diaphragm disk
- Built-in lower LED illumination
- Retractable upper halogen illumination
- AC adapter
- 3 AA and 2 AAA batteries
- Plastic case
- User manual and lifetime warranty

Levenhuk 40L NG and Levenhuk 50L NG models look quite similar... what's the difference between them? Only the K50 kit? Levenhuk Customer Service:

Hello! Will I be able to observe sperm with this microscope? And what about Levenhuk 2L NG? Will I need something in addition? Blank slides and cover slips? Where can I find them? Are they disposable? Levenhuk Customer Service:
Levenhuk 2L NG and Levenhuk 40L NG are perfect for this purpose. Yes, you will need blank slides (https://www.levenhuk.com/catalogue/accessories/levenhuk-g50-blank-slides/) and cover slips (https://www.levenhuk.com/catalogue/accessories/levenhuk-g100-cover-slips/).

Yes, Levenhuk 40L NG Microscope is equipped with upper illumination, which allows observing in reflected light.
Hello! We wanna give this microscope to our 10 years old kid. What else should we buy to work with it? Preparations, slides, something else? Or maybe advise us some other model with similar features and price. Levenhuk Customer Service:
We recommend Levenhuk N38 NG Prepared Slides Set - https://www.levenhuk.com/catalogue/accessories/levenhuk-n38-ng-prepared-slides-set/. You can also consider another microscope model, Levenhuk 50L NG Lime Microscope, which comes with a large set of additional accessories - https://www.levenhuk.com/catalogue/microscopes/levenhuk-50l-ng-lime/.

Hello! The microscope is great! But I have one little problem. When I observe fresh blood through 4x, 10x objective lenses - everything's fine, the picture is clear. But when I try to use 40x lens, the image starts to blur. I use Levenhuk G50 glass slides. So what's the problem? Thank you in advance. Levenhuk Customer Service:
We also recommend using coverslips: Levenhuk G100 Cover Slips, 100 pcs https://www.levenhuk.com/catalogue/accessories/levenhuk-g100-cover-slips/. If this doesn't solve the problem, please contact our Customer Service Department: https://www.levenhuk.com/feedback/.
I managed to remove Barlow lens (thank you!), but now eyepieces do not sit tight in the eyepiece tube. Just hanging there loosely. Why? Levenhuk Customer Service:
To use eyepieces you don't need to remove Barlow lens.
how to remove the Barlow Lens?? Levenhuk Customer Service:
To remove the Barlow Lens from the Levenhuk 40L NG Microscope you just have to pull it out of the eyepiece tube.

Yes, Levenhuk 40L NG Microscope is equipped with a rotatable head.
What's the difference between Levenhuk 40L NG and Levenhuk 50L NG? Levenhuk Customer Service:
The only difference between these models is that the Levenhuk 50L NG microscope comes with experiment kit.
Hello! I'd like to know if there's any difference in optics quality between Levenhuk 40L NG and Levenhuk 50L NG models? Levenhuk Customer Service:
Levenhuk 40L NG and Levenhuk 50L NG are the same microscope models but with different accessories included.
Is it possible to display images on the PC monitor? Where can I purchase a camera and software? Maybe you can recommend a microscope that comes with a camera? Thank you! Levenhuk Customer Service:
1. Yes, there is such possibility. For this purpose we recommend using Levenhuk C310 NG Digital Camera, USB 2.0 - https://www.levenhuk.com/catalogue/accessories/levenhuk-c310-ng-digital-camera/. Installation CD with Levenhuk ToupView image editing software and the required drivers is included in the kit and can also be found on the product description page in the "References and Downloads" section. 2. We recommend that you consider Levenhuk D50L NG Digital Microscope - https://www.levenhuk.com/catalogue/microscopes/levenhuk-d50l-ng/.
Is it necessary to use digital camera with this microscope? Levenhuk Customer Service:
It's not necessary to use digital camera with Levenhuk 40L NG Microscope, unless you want to study samples on your PC screen or take images or record videos of your observations.
why your microscopes for children are more expensive than kids microscopes of other brands? Levenhuk Customer Service:
Levenhuk children microscopes (for example Levenhuk 40L NG) are teaching models, meaning they are more than just toys. These Levenhuk microscopes feature sturdy metal bodies and optics made of glass. On the other hand most of kids' microscopes in the market are toys, they are usually made of plastic and provide low magnifications (around 100x).
All your answers to questions like "Can I see 'smth' with this microscope" are negative. So I'd like to ask - what CAN I observe with it? Levenhuk Customer Service:
Levenhuk 40L NG Microscope allows you to see unicellular ciliated protozoa in a drop of pond water, study the complex structure of frog skin, examine a blood smear in detail and see many other interesting things hidden from the naked eye. All the 'negative' answers are for the questions implying professional use of this microscope, but this is a teaching model and it's not intended for professional use.
Is image quality fine under 1280x magnification? I heard that images significantly lose in quality under high magnifications. Thank you in advance! Levenhuk Customer Service:
Unfortunately yes, the higher the magnification the lower image quality will be. But the Levenhuk 40L NG model maintains quite acceptable image quality even under its highest magnification of 1280x.
I have ordered this microscope... and I wonder if it's possible to increase magnification up to 2000x? Levenhuk Customer Service:
Unfortunately, it is not possible to obtain an increase of more than 1000x without quality loss. You will need an oil-immersion objective, this objective (usually 100x or more) designed to work with a drop of special immersion oil.
So is this microscope suitable for blood studies? Your replies are controversial. Thank you in advance for the answer. Levenhuk Customer Service:
The Levenhuk 40L NG microscope is an educational model. It is not suitable for blood examinations. Please take a look at Levenhuk 850B Biological Binocular Microscope - https://www.levenhuk.com/products/microscope_levenhuk_850b/

Yes, you can see cells under the Levenhuk 40L NG Microscope.
How big is the depth of focus in transmitted light for this microscope? For example, how deep a sand grain will be seen at 160x-200x magnification? I am an entomologist so I have to observe really small insects or their body parts, stereomicroscopes are not always manage to do the job. Levenhuk Customer Service:
Depth of focus means how clearly observed an object appears to the observer's eye. The depth of focus is unique for every person. You can find out your depth of focus for any given microscope only by looking in it yourself.
I don't understand what's the purpose of this one big screw, the one that is closer to the stage? Levenhuk Customer Service:
This is the focusing knob, you need it to raise and lower the stage to adjust the view.
