These are new
items which emits ultraviolet light at a wavelength of 385nm. It is powerful enough to make gems and minerals
fluoresce even in normal room lighting. This field tested UV
mineral-quality flashlight comes with a professional grade filter
to block white (visible) light (also emitted from the LED’s),
which otherwise would make it difficult to see the fluorescent
reactions. Many long wave reacting gems such as rubies and diamonds
show a strong fluorescence even in bright room lighting.
This flashlight
will reveal all special fluorescent markings on recent United
States paper currency $5 or greater. You can check for authentication
marking on credit cards and other forms of ID (our Texas Driver's
Licenses have "Texas" in yellow letters imbedded). Privacy
marking pens such as the Sanford Security Marker (offered separately)
work especially well.
Antique dealers
and artifact collectors can detect repairs (the glue usually shows
brightly in the long wave UV light) or reworked arrow and spear
points out of flint. Recent chipping on Texas chert shows brighter
reaction than weathered and old flaking.
The flashlight ships
ready to use - complete with 3 AAA batteries and a convenient
nylon holder to carry on a belt.
