Abstract
A counterfeit detection device that is useful for optically examining the security features of currency to determine its authenticity. The apparatus places the currency at the object plane of a magnifying lens suitable for enlarging the image of the microprinting as well as examining other fine features of the bill. In one embodiment, the device consists of a rear illuminating light source a bill positioning slot a magnifying lens, and an environmental light shade. Further embodiments include a capability of front illumination to detect the color shifting ink, an ultraviolet light source causal to viewing the phosphorescent glow of the polyester thread with its identifying color. And finally, a version with a swing-away lens to view the watermark unmagnified.
Claims17
A counterfeit detection device for magnifying and observing the detailed security features of a document having at least one security feature wherein;
- said counterfeit detection device is comprised of at least an omni-directional magnification lens having at least a first surface, a second surface, and an object plane located proximate the surface of said document having at least one security feature;
- said first surface of said omni-directional magnification lens is substantially spherical and said second surface of said omni-directional magnification lens is substantially planar;
- said omni-directional magnification lens is mounted to and surrounded by an ambient light blocking shroud;
- said document having at least one security feature located within a document locating feature of said counterfeit detection device proximate said object plane;
- a light source located distal to said document having at least one security feature wherein said light source illuminates from a rearward side of said document having at least one security feature;
- said rearward side illumination being useful for viewing watermarks, microprinting, internal polyester threads with printing and microprinting, internal polyester thread fluorescence, split images and the like;
- and
- said light source being connected to a power source causal to illuminate said light source and said rearward side of said document having at least one security feature.
A counterfeit detection device for magnifying and observing the detailed security features of a document having at least one security feature wherein;
- said counterfeit detection device is comprised of at least an omni-directional magnification lens having at least a first surface, a second surface, and an object plane located proximate the surface of said document having at least one security feature;
- said omni-directional lens being mounted in a lens shroud useful for blocking ambient light;
- said lens shroud further having a document locating feature proximate said object plane;
- said lens shroud additionally having a pivotal feature to allow said omni-directional lens and shroud to be pivoted away from said document having at least one security feature;
- said pivotal feature being useful for viewing features such as watermarks and the like unmagnified within said document having at least one security feature;
- a light source located distal to said document having at least one security feature wherein said light source illuminates from a rearward side of said document having at least one security feature;
- said rearward side illumination being useful for viewing watermarks, microprinting, internal polyester threads with printing and microprinting, internal polyester thread fluorescence and split images;
- and
- said light source is connected to a power source causal to illuminate said light source and said reward side of said document having at least one security feature.
