Description

General information

Levenhuk D70L Digital Biological Microscope features superb image definition, especially at the edges, ensured by hardware reliable performance. The basic configuration provides wide image processing possibilities.

The Levenhuk D70L is used for observations of transparent and opaque objects in transmitted light using the bright field method, for biological use and teaching demonstrations.

The microscope includes:

Stand with focusing arm
Base with built-in illumination
Bracket with stage
Revolving nosepiece with objectives
LCD display, memory card slot
Diaphragm disk with 5 color filters
Illumination lens upper/lower

Levenhuk D70L modules:

Focusing arm
The focusing arm located on the stand allows vertical movement of the stage. Handles are lined up at the both sides of the stand. The total focusing value is at least 10 mm (0.4 in).

Stage
The stage is fixed on the bracket secured on the focusing arm block. The specimen holder is located on the stage surface, and the diaphragm disk is attached to the lower part of the stage. A stopping screw limits movement of the stage bracket, which eliminates possible contact between the objective and the specimen.

Revolving nosepiece
The revolving nosepiece holds the objectives; to replace an objective, rotate the ring until it reaches the fixed position.

Head
3.6" LCD display.

Maintenance of the microscope

The microscope should be kept clean and protected from damage. When it is not in use, cover the microscope with a special case included.
To maintain the microscope, regularly wipe dust off it, then clean it with a soft cloth slightly moistened with acid-free petroleum jelly. Afterwards, wipe it with a dry, soft, clean tissue.
Metallic parts should be kept clean. Special attention should be paid to maintaining cleanliness of the optics (especially objectives and eyepieces).
Never touch the optic surfaces with your fingers.
In case dust soils the objective lens deep in the casing, carefully wipe the lens with a clean cotton swab slightly moistened with Levenhuk cleaning spray or spirits mixture. If you notice dust inside the objective or a film on the inside of the lenses, the objective should be sent for repair.
Never attempt to disassemble objectives and eyepieces; doing so would void the lifetime warranty.

Denialla St (2017.12.24)

Hello! I would like to clarify a few moments:
1. Will the microscope work completely autonomously? Without connecting it to the mains? As I understood, batteries provide illumination. But what about the display?
2. Can I replace eyepiece and/or objective lens in order to increase magnification? If yes, then what items would you recommend? I saw somewhere in the comments that wf16x is suitable, but 20x already not. Levenhuk 10x/18 is ok or not?
3. Can I use Barlow lens?
4. Will I be able to transfer images directly to the screen or projector or only through a PC?
5. Where can I see images and videos made with this microscope?

Customer service:

1. Levenhuk D70L Microscope can be used without connection to the mains, but only with an eyepiece. LCD display won’t work.
2. The microscope has a standard barrel diameter of 23.2 mm. You can use 16x eyepiece, as well as 10x/18. There are no suitable objective lenses in our product range.
3. No, the design of the microscope doesn’t allow the use of a Barlow lens.
4. Images are displayed on the LCD screen. You can send photos and videos to a PC using cables or memory card.
5. Photos and videos can be viewed on the microscope display, as well as on a PC monitor when transferred.

nobody (2017.04.10)

My LevenhukLite Software cant see Levenhuk D70L. This microscope can be connected to the PC only as a flash drive? can I transfer online from the microscope camera to the computer screen?

Customer service:

That is right, the computer sees the Levenhuk D70L digital microscope as a flash drive, it is impossible to broadcast an image from the microscope camera to the computer screen online.

John (2017.04.10)

Please, tell me the parameters of the AV cable for connecting the microscope to the TV. What the connector this is…such a small plug diameter? It looks like a mini 2.5 jack, but i need to know for sure. Should there be two or one RCA on the TV side or what?

Customer service:

The Levenhuk D70L Digital Microscope cannot be connected via AV cable. The plug you are asking about is the power connector.

Daniel Patton (2017.01.09)

Tell me, at what expense we achieve such a powerful magnification of 1600õ? We want to use the microscope in the paper production to determine the color of the fiber. Do the filters allow to distinguish blue, red, yellow colorization?

Customer service:

1. Levenhuk D70L model provides 400x optical magnification. 1600x is obtained due to digital interpolation ("stretching" of the image). 2. Unfortunately, we did not conduct such studies and have no answer to this question.

Carla Moss (2014.10.11)

Is this model suitable for observing bacteria?

Customer service:

Amateur microscopes do not allow you to observe bacteria, because most bacteria are too small and can be seen only under 1200x magnification and the sample has to be stained. So you will need an advanced instrument and special sample preparation methods. We recommend that you consider this model: Levenhuk D320L Digital Biological Microscope - http://www.levenhuk.com/catalogue/microscopes/levenhuk-d320l-base-3m-digital-monocular-microscope/

You can purchase Levenhuk K50 Experiment Kit separately, user manual is included in the kit.

Melissa (2013.03.22)

I am eager to know how capable is this microscope of showing non-transparent objects (metal, razor blade, stone) at 1600x magnification. I mean is there a way to install powerful upper illumination?
I am also interested about how much power requires a microscope that allows observing frozen water (ice) structure.
Thank you for detailed answers.

Customer service:

The Levenhuk D70L model does have upper illumination out
of the box!

Water crystals are usually observed at 400x
magnification.

Mary Conger (2013.03.16)
