40x Magnifying Glass Eye Loupe

The Perfect Part 40x Magnifying Glass Eye Loupe is a compact optical magnifier built for jewellery inspection and watch repair. Its zinc-alloy frame and glass optics deliver 30x40 magnification in a black finish. The tool suits hobbyists and professionals who need close-up detail work on small components.

Practical limits of 30x40 magnification

At 30x40 magnification the usable field of view is very narrow and the working distance is extremely short, so the loupe must be held close to the eye and the object. Ambient lighting becomes critical because the small 40 mm lens gathers limited light. Users needing a wider view or hands-free operation will find this form factor restrictive.

40 mm lens diameter decides suitability

The 40 mm (1.57 inch) lens diameter sets the maximum viewing area and light intake for this magnifier. If the task requires inspecting larger surfaces or working at a greater distance, a larger-diameter optic or a different magnification range will be necessary.

Questions about this item

How do I choose between the 30x and 40x magnification options?

This loupe provides a fixed 30x40 magnification range; there are no separate versions or capacities to select.

What does the 40x figure mean when I hold the loupe to a watch movement?

At 40x the optics enlarge the subject forty times, revealing fine gear teeth and hallmarks through the 40 mm lens.

Does the zinc-alloy frame affect the optical standard or limit the usable field?

The frame holds the optics lens securely; the 40 mm diameter sets the viewing area, and the 30 mm body depth keeps the working distance short.
