Worldclass Optics Made in Germany

Sits like a pen in your hand: A fantastic tool, very sturdy in a metal housing combined with premium optics for a thorough inspection.

Features:
This pocket microscope is available in the following magnifications: (30x 40x or 50x). Please choose yours below. By using the rotating ring, fine focusing is possible. The achromatic precision lens is scratch-resistant and creates a very high sharpness. Dioptre compensation of up to +/- 4 dpt is possible. Spectacle users need not wear their spectacles! The sturdy metal housing completes the pocket microscope.

With the optional stand adapter (optional below), working with the pocket microscope becomes wobble-free! Also, you can install and "upgrade" this pocket microscope by using scales which you can easily install into the stand adapter. You can view the scales here.
Highly recommended due to the high magnification. The 'Illumination Unit' needs the 'Stand Adapter Unit' - together with the pocket microscope they form one complete unit.

A handy Illumination Unit (Picture 2), Duo Scales (No Picture) and a Stand Unit (Picture 3) are available and can be chosen below.

Chromatic aberration is caused by a lens having a different refractive index for different wavelengths of light (lens dispersion), meaning that different colors focus at different distances from the lens. Longitudinal and lateral chromatic aberration of a lens can be seen as "fringes" of color around the image.

Chromatic aberration of a single lens causes different wavelengths of light to have differing focal lengths.

An achromatic doublet has the same focal length for red and blue light.

As can be seen above, chromatic aberration can be minimized by using an Achromatic Lens or Achromat, in which special optical materials with differing dispersion are assembled together to form a compound lens.
