DUAL UV Ultraviolet Long & Shortwave Lamp with filter for Mineral Detection

Description

U450 Dual Fluorescent Ultraviolet Detector: portable short and long wave light with Optical Filter - for Stamps, Minerals, Currency, Paper Varieties, Detecting Fakes and Sterilizing instruments.
GEMSTONE and MINERAL INSPECTION
UV Light can react with the chemicals of a mineral specimen and cause it to glow, called fluorescence. Color and intensity of the fluorescence can identifty many materials. Some minerals and gemstones will fluoresce brilliantly under shortwave UV light, others under longwave.
Combines two functions in one device - the combination of short and long UV rays (switchable between 254 and 380nm)
This versatile Dual shortwave & longwave UV light
with optical filter supplied
provides assured fluorescence detection of minerals, invisible phosphor and sterilizing instruments.
Detect amber
(glow yellow or blue light for true amber - fake amber won't glow)
Hand held portable model.
Batterie operated: requires 4 AA batteries (not included)
Retail .99
Collectors who wish to find tagging on stamps, as well as collectible paper varieties and errors in tagging, need to acquire and use a UV lamp. Tagging errors, including missing tagging, are known and sought out by collectors!
Stamps, banknotes, credit cards, phone cards, minerals, fossils, etc can be examined for detection of phosphorescence
Good for the stamps of Canada (including the Winnipeg Tagged), USA, Mexico, France, Norway, Hong Kong, China, Russia, Israel and the United Kingdom
UV Lamps are pretty easy to use but it has been pointed out to me recently, that not everyone understands that they must be used in DARKNESS. One customer mentioned to me that that may seem self-evident to me but that it should have been in the instructions. So chastened, I am adding this to my information!
Note: no stamps or minerals come with this product! The pictures show these items only to demonstrate what the lamp can do. You are purchasing only the lamp with filter.

Shortwave 254 nm FUNCTIONS:
Detection of phosphur tagging on stamps.
The Winnipeg tagged stamps (and Sc #1696,1699) of Canada as well as most USA and UK issues will not show up under long wave rays and can only be detected with shortwave units with an optical filter.
Some stamps, for example the British Queen Elizabeth II Machin definitives, have a multitude of collectible luminescent varieties.
with the use of shortwave UV,
paper fluorecence
can be determined as an attribute to distinguish between varieties
Verify the authenticity of various items
such as: stamps, banknotes, phone cards, credit cards, customs and revenue stamps, tickets, etc
Used for prospecting for metalliferous ores
(Note: rocks should be within 12 inches of the lamp to get fluorescent response)
Detect amber
(glow yellow or blue light for true amber - fake amber won't glow)
UV light for microbiological testing, in geology and archeology can show a variety of minerals, determine the authenticity of the fossil heritage
use for sterilizing instruments
Collecting tagged stamps requires knowing a few basic words:
luminescent, fluorescent and phosphorescent
.  "
Luminescent
" refers to a substance that glows when exposed to UV light. If the luminous coating or ink on a stamp continues to glow for a short time when the UV light is switched off, then the coating on the stamp is
phosphorescent
. If the stamp ceases to glow when the UV light is switched off, it is called
fluorescent
.The luminescent coating applied to a stamp is called "
tagging
" or "taggant." Once a stamp has had taggant applied, it is referred to as being "tagged," and so is a stamp printed on paper coated with taggant prior to printing.
Note:
Exercise maximum care when working with a UV lamp. Never look directly into the light coming from a UV lamp. It will not look very bright or ferocious, but looking into it could burn the corneas of your eyes. This is a painful and potentially serious condition that can cause permanent loss of visual acuity. It helps to wear glasses when using a UV lamp. Keep your hands away from the light too, because exposure to UV light can burn. Wear gloves and sunscreen if you will be working with a UV lamp for extended periods.The best way to check luminescence with a UV lamp is to arrange the stamps you wish to check by setting them out in a work area. The work surface itself should not be luminescent because that will overpower the luminescent properties of the tagged stamps.
Darken the room by turning off all the lights. Switch on the UV lamp. Make your observations quickly, and then switch off the UV lamp and turn on the ordinary lights. Working in short, concentrated spurts is better for your eyes and will help keep the UV lamp in good operating order for a longer period.
