A high-grade focusable measuring magnifier with a Triplet lens-system made from silicate glass. The optics are unbeatable making this a favorite amongst The Loupe Store clients.

The ocular is focusable giving you a high resolution image. Spectacle wearers need not wear their spectacles while using the ocular.

A scale, division 0.1 mm on a length of 20 mm is included and six other scale/reticule types are optionally available (click here for details). To add the extra scales/reticles you can either add them below in options or click here to view the scales/reticles.

Magnification: 7x
Diameter: Ø 23 mm

The Triplet lens-system combines the aplanatic features of a distortion free image with the color correction of an achromatic lens making this magnifier a highly important tool for viewing the true color of the examined object.

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.

The Triplet lens-system combines the aplanatic features of a distortion free image with the color correction of an achromatic lens making this magnifier a highly important tool for viewing the true color of the examined object.
