Watchmaker's loupe with a biconvex white glass lens. UV-absorbing crown glass is used in the manufacture, as is also used for the production of prescription spectacle lenses (refractive index n=1.52). Black anodised aluminium frame with ventilation hole (prevents fogging of the lens). The lens diameter is Ø 23 mm.

The very good workmanship of the watchmaker's loupe, the excellent quality of the silicate glass lens, which is scratch-resistant and solvent-resistant, as well as the high-quality, extremely robust and impact-resistant aluminium design of the frame make this watchmaker's loupe a standard inspection tool that meets all workshop requirements.
