Description
Crystal-Clear Optics
Each interchangeable lens plate is ground and polished from optically pure glass. The result is a distortion-free, bright image that helps goldsmiths and jewellers work for longer with less eye strain.
Click-Fit Convenience
Changing magnifications is effortless: press the two rear tabs, lift out the existing plate and snap the new one into place. No tools, no fuss—just seamless workflow on the bench.
Designed for Precision
OptiVISOR lenses preserve true colour rendition and depth perception, leaving both hands free for soldering, engraving or stone-setting. The robust frame tolerates workshop conditions while the lightweight design keeps comfort high during extended sessions.
A Magnification for Every Task
From broad finishing at 1.75 × to ultra-fine inspection at 3.5 ×, there is a lens in the series to match every stage of the jewellery-making process. Swap plates as your work progresses—coarse filing, claw seating, final inspection—without changing your head-gear.
All five plates share identical optical quality and mounting dimensions; they differ only in magnification and working distance. Lower powers (Nº 3 & 4) give a wider field of view and allow you to keep tools further from the eyes—ideal for soldering or filing. Higher powers (Nº 5, 7 & 10) bring the work very close for meticulous detailing such as micro-setting or inspection of hallmarks, but they naturally shorten the focal distance. Select the lowest power that still reveals the detail you need; this will maximise comfort and depth of field during long sessions at the bench.
