Bausch & Lomb 10X Hasting Triplet Aplanatic Watchmaker's Eye Loupe

For professionals who prefer a watchmaker-style loupe, this Bausch & Lomb eye loupe features a highly corrected Hastings triplet lens at 10X magnification. Unlike standard watchmaker loupes that use a single lens element, this model incorporates a triplet — three lenses bonded together — delivering significantly improved optical performance. The Hastings triplet design corrects for both spherical and chromatic aberrations, resulting in a sharper, truer image across the full field of view.

Features

• Hastings triplet lens construction with three bonded lens elements
• 10X magnification for detailed watchmaking and bench work
• Corrected for spherical aberration, minimizing distortion across the lens field
• Corrected for chromatic aberration, reducing color fringing for truer color rendering
• Watchmaker-style loupe form factor for familiar, comfortable use
