Best uv lamp for minerals.

However a few minerals will show up better under lw. While this approach is considerably more expensive than using ordinary blacklight bulbs it provides much purer uv light allowing less visible light to mask the fluorescence.

There is a lamp stand available for this lamp for hands free use.

The uvp mini uv lamp is currently the most affordable portable uv field lamp on amazon. It is a basic no frills field lamp. It s small and lightweight size make it ideal for taking it along with you. Uv sensitive beads react to the intensity of the light and change color they all start out white and darken based on the intensity of the uv.

Note that these lights must have a uv pass visible blocking filter a must for any light used with fluorescent minerals even led lights. Short wave uv lights are the most commonly used by fluorescent mineral collections since about 80 to 90 of all fluorescent minerals will fluoresce brighter under short wave sw than under long wave lw. This is an attempt to visualize the pattern and intensity of the uv light generated by each light. Shortwave uv has been used for over 100 years in the desinfection of baterial and viral organisms.

Midwave mw bulbs have become more popular among fluorescent mineral collectors recently because certain minerals display most prominently at the uvb wavelengths around 311nm. The best most efficient longwave uv source to use for mineral fluorescence is a special white phosphor coated blacklight bulb combined with an external visible light blocking filter. This specific wavelegth of uv radiation is in the uvc range of ultraviolet light. Ultraviolet light is electromagnetic radiation in the part of the spectrum between x rays and visible light approximately 180nm to 400 nm.

This is the uv lamp we used when taking the pictures for the minerals on our fluorescent minerals page. Broadband uvb bulb have been around for a while using a phosphor driven by low pressure mercury emission. Uv lamps used to illuminate large mineral displays or used for outdoor field work have much higher voltages than the small uv lamps used for specimen examination by students. 365nm longwave led flashlights are a must.
