Best Uv Light For Minerals

There s a silver lining here though.

Best uv light for minerals.

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. It offers almost 3 watts of uva output radiant and is unbelievably bright. Uv resources is located in santa clarita ca. Some of the latest high power uv led flashlights will allow your eyes to find this material starting at around 80 100 feet away.

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. If you are not familiar with uv and uv lights you can learn more under the uv topics pages.

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. Its uv systems are combination led and uv task lights which can automatically switch between lights and tilt up to 15 degrees.

Midwave mw bulbs have become more popular among fluorescent mineral collectors recently because certain minerals display most prominently at the uvb wavelengths around 311nm. As a matter of fact that is how we humans are able to see the minerals. The same uv light in particular uv c light which has a wavelength between 200 and 280 nanometers while visible lights smallest wavelength measures 380 nm. But that is not always the case with most other longwave uv reacting minerals.

Specifications used to promote many of the lights on the market are misleading and inaccurate quoting the overall power used to light the bulb not the much lower power of the uv generated by the bulb. Broadband uvb bulb have been around for a while using a phosphor driven by low pressure mercury emission. Why do minerals glow more under short wave ultraviolet light. All minerals have the ability to reflect light.

Since most of the visible light is filtered and only uv light is passing through short wave ultraviolet lights are the best black lights for minerals. However a few minerals will show up better under lw.
