Levenhuk D70L Digital Biological Microscope

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.

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.
