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.

* 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.
Some things you can see under a microscope:
Levenhuk D70L Digital Biological Microscope is also compatible with Levenhuk digital cameras (additional cameras are purchased separately). Levenhuk cameras are installed in the eyepiece tube instead of an eyepiece.

Is there any additional information you might need?
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?
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.

Only one thing… the SD card in the kit is 2Gb, correct the info! That was a great surprise though!:)

And one more question: if I attach an upper lighting to D320L, will I be able to observe opaque objects?
I'd like to be able to see bacteria and mites, and different opaque objects.
Digital Biological Microscope does not provide an
opportunity to attach Levevnhuk 20x eyepiece instead of
the nosepiece.
in bright-field mode only. The option of observing using
dark-field mode is available in other models, for example

You can purchase Levenhuk K50 Experiment Kit separately, user manual is included in the kit.
I am also interested about how much power requires a microscope that allows observing frozen water (ice) structure.
Thank you for detailed answers.

Water crystals are usually observed at 400x
magnification.
1600x magnification: is it just optical or combined with digital?

Levenhuk D70L model doesn't have any built-in memory.
it has a memory card slot, so images can be saved on

The highest optical magnification of the Levenhuk D70L
Digital Biological Microscope is 400x; its digital
