Technical Specifications of UV Related and Fluorescent Mineral Technologies

​

Unlike daylight rock collecting, the fluorescent mineral hobby requires some special equipment:  UV lights filtered to block the visible light from the UV bulbs (lamps) but let out the UV, protective front panels for mineral displays to protect viewers from UV, special lamps/bulbs to generate UV, and UV LEDs as a new and efficient way to generate UV.

​

As we discover new specifications and details on these technologies we will add them here.  If you are aware of any technical data which should be included here please let us know.
