The H.E. Harris #1020 (SKU: 9ANC1639) is a professional-grade pocket magnifier designed for high-resolution inspection. While standard reading glasses are used for general viewing, the 16x loupe is a technical tool used by philatelists and numismatists to identify microscopic details such as plate flaws, "re-entries" on stamps, or mint mark varieties on coins.
The Model 1020 is favored for its "Wide Field" design, which offers a larger viewing area than typical high-power jeweler’s loupes, reducing eye strain during prolonged use.
Double Lens System: Features an optically ground and polished double-lens configuration. By using two lenses in tandem, the loupe provides a crisp, high-power magnification with significantly less spherical aberration (distortion) at the edges than a single-lens magnifier.
Wide Field View: Equipped with a 20 mm viewing field. In the world of high-power optics, a 20 mm lens is considered "wide," allowing the collector to see an entire mint mark or a small stamp surcharge without moving the loupe.
Chrome-Plated Swing Housing: The lenses are protected by a heavy-duty chrome-plated metal case. This housing serves two purposes: it protects the glass from scratches when closed and acts as a sturdy handle when swung open.
Pocket Portability: Designed for "on-the-go" use at shows or auctions. The loupe folds into a compact metal package that easily fits into a pocket, purse, or travel kit.
The "Retail Pack" designation refers to the consumer-ready blister packaging (often labeled as SKU #0794826261), featuring an easy-to-display card with usage instructions.
Magnification: $16\times$ Power.
Lens Diameter: 20 mm.
Material: Polished optical glass lenses with a chrome-finished metal housing.
Weight: Approximately 0.5 lbs (in retail packaging).
Focal Distance: Being a high-power loupe, the "sweet spot" for focus is very close to the object (typically within 1 inch).

High-power loupes require a specific technique that differs from standard magnifying glasses:
Bring the Loupe to the Eye: Hold the loupe directly against your eye (or eyeglasses).
Bring the Object to the Loupe: Move the stamp or coin toward the loupe until it snaps into sharp focus.
Lighting: Ensure the light source is coming from the side so the metal housing does not cast a shadow over the area you are trying to inspect.
