This is the LED version of the Peak with Triplet System. The magnifiers are the same as the stand-alone Peak Triplets, but with a LED integrated into the handle-piece, which is powers by two 1,5 Volt batteries (not included).
This Peak Magnifier (See Model Number in Specifications above) was made for professional use meeting the best quality inspection requirements throughout specialized industries.
Combined with a glass scale plate, and a focusable lens, this Peak magnifier has the following specifications:
Specifications:
- Peak scale magnifier
- Magnification 30x, 20x or 15x
- Triplet lens system
- Distortion free optics, anti-reflex coating
- Horizontal cross hair with (metric) scale on glass plate 5 mm length with a 0.05 mm division and a ø7 mm field of view
- Weight: 35 grams
- Standard Scale included
- Black (white writing) scale optional
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.
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.
