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.
All this provides extremely high image quality and long microscope life without any special maintenance.
Magnification
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.
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!
Illumination
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.)
Power supply
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.

Levenhuk 40L NG Microscope is compatible with Levenhuk C NG digital cameras (purchased separately). Levenhuk C NG cameras are installed in the eyepiece tube instead of an eyepiece.
