Spi 14-158-0 Triplet Lens Loupe 10x 0.8281 Inch

Product Description

The SPI 14-158-0 is a folding triplet lens loupe designed for high-clarity close-up inspection work. The triplet lens assembly uses three precision-ground optical elements to minimize chromatic and spherical aberration, producing a flat, distortion-free field at 10x magnification. The lens diameter measures 0.8281 inches (53/64 inch). The folding design protects the lens when not in use and keeps the tool compact for pocket or tool bag carry. Jewelers, machinists, quality control inspectors, and field technicians routinely use this type of loupe for reading fine graduations, inspecting surface finish, and examining small components.

This loupe suits precision inspection tasks in trade and industrial settings where a portable, hand-held magnifier is required. Common applications include reading fine thread profiles, inspecting weld quality, examining electrical component markings, and verifying surface condition on machined or finished parts. The single-lens folding body keeps the optical element protected during transport and ready for fast deployment on the job.

Key Features

• 10x magnification for detailed close-up inspection
• Triplet lens construction using 3 precision-ground elements reduces aberration and distortion
• Lens diameter of 0.8281 inches (53/64 inch) provides a usable field of view for small-part inspection
• Folding design protects the lens and makes the loupe pocket-portable
• Hand-held form factor requires no stand or mounting hardware
• No external light source required, though supplemental lighting improves contrast in low-light conditions

Compatibility

Designed as a general-purpose hand-held inspection loupe compatible with any application requiring 10x magnification and a triplet-quality optical element in a folding body.

Installation Notes

No installation is required for this hand-held loupe. To use, unfold the lens from the protective body and hold the loupe at the correct focal distance from the subject — typically close to the lens focal length — for a sharp image. Keep the optical elements free of fingerprints and debris by storing the loupe in the folded position when not in use. Clean lens surfaces with a soft, lint-free cloth only.
