Jeweller's Loupe — 30× Triplet Achromatic, Black Chrome, 21mm Lens

A 30× triplet loupe is the gold standard in gemology, mineralogy, and electronics inspection — three-element optics eliminate the chromatic and spherical aberration that make cheaper loupes useless at high magnification.

The triplet design stacks three cemented optical elements to produce a flat, colour-correct field across the full 21mm aperture — critical when evaluating mineral inclusions, circuit traces at 0.1mm pitch, or the structural quality of gem facets. The fold-out body protects the lens and acts as a focusing jig: open until the specimen appears sharp (typically 8–12mm working distance at 30×). Black chrome finish reduces stray light reflections.

• 30× magnification; 21mm achromatic triplet lens — flat field, colour-correct
• Black chrome aluminum body; fold-out protective housing
• Working distance ~10mm; resolves features as small as 0.05mm
• Includes leather case and neck lanyard
