The Loupe System offers three different models, with varying magnification: a 6x Model 01 loupe, 3x Model 02 loupe, and a 10x Model 03 loupe, each fully clad from top to bottom in black silicone rubber.
The Model 01 loupe and the Model 03 loupe provide 6x and 10x magnification respectively through five multi-coated optical glass elements arranged in three groups, while the Model 02 loupe provides 3x magnification through four multi-coated optical glass elements also arranged in three groups. Both were designed according to the same principles as a camera lens. The surfaces of each lens have had several special coatings applied to them, which are designed to maximize contrast, color saturation and color fidelity as well as minimize flare.
The 6x Model 01, for example, is capable of resolving much more detail than the eye can see (well over 30 lp/mm @ MTF 0.8, versus 5-10 lp/mm at best for the human eye), thus providing a very bright, contrasted and crystal-clear viewing field from edge to edge.
The complete absence of chromatic aberration, combined with the very tight control over geometric distortion, provide a breath-taking viewing experience which has never been achieved before in a hand-held loupe.
Each loupe comes provided with two interchangeable silicone rubber top elements. The standard one, which gives a 40mm-wide viewing field for Model 01 and a 60mm-wide field on Model 02, places the eye at the optimal distance to take advantage of the best optical performance which the loupe can offer. The alternative top element places the eye closer to the loupe, thus providing a wider 50mm viewing field for Model 01 and an unrivaled 70mm viewing field on Model 02, at the cost of a small loss in visual acuity (which – though measurable – is not noticeable by the human eye).
