What is short-wave UV?
Sep 16, 2021 · I was just starting out on gemology, do I really need a short wave UV (254nm) alternative to a long wave UV (365nm) Coz a short and long wave UV light cost around $190 and a long wave cost only $30. I’m on a tight budget, do I need to spend another $160 for the long and short wave version?

Have you ever wondered what kind of black light is used to make minerals glow? Do they emit short wave or long wave UV light? If you have a mineral collection and you want to make it glow, you should be aware of which is the best kind of black light for minerals. Here’s a hint. Short wave ultraviolet light is the best black light for minerals.
The Best Portable Short Wave UV Lamps
One of the key tools for any serious mineral hobbyist to have is a portable shortwave UV light to use out in the field. When in comes to finding a good UV field lamp, there are several to choose from. All of which come with there own pros and cons.
1. The UVP 95-0158-04 Mini UV Lamp
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. The downside, however, is that it is only a 4 Watt UV lamp, which means you will need to be close to the minerals with the UV lamp to see them glow. This is not the best UV lamp if you simply want to walk around shining your UV light on the ground. 1. 4 Watt 2. Short wave Ultraviolet Light 3. Sm...
2. UV Shortwave Mineral Lamp – Battery Powered
This shortwave portable UV light is rechargeable with a very long battery life of 7.5 hours, which makes it perfect to take along with you whenrockhounding for minerals at night. 1. UV Mineral Lamp 8W 254 nm UVC Shortwave Battery/DC in with Filter. 8.4 V DC input for charger. 2. Long battery life of 7.5 hours continuous power on a single charge 3. Beautiful and sturdy lightweight storage/carriage case for convenient transport and carrying while traveling 4. Enjoy peace of mind with 30 days re...
When it comes to long wave UV lights, the selection is huge and the cost is minimal. That is the nice part of using long wave lights. The downside, as I mentioned earlier, is that we don’t get the glow from our minerals that we would by using short wave UV lights. With that said, these long wave UV flashlights are a great way for mineral hobbyists ...
Ultraviolet light is a type of electromagnetic radiation, just like radio waves, infrared, X-rays and gamma-rays. UV light is not visible to the human eye. Electromagnetic radiation is transmitted in waves or particles at different wavelengths and frequencies called the electromagnetic spectrum. It’s on this spectrum that we find UV light, X-rays a...
Long wave Ultraviolet Light
Long wave UV lights have filters which screen out a lot of the visible light they produce, but not all. These filters are generally inexpensive to buy for that reason. Because of that, the black lights we use as hobbyists are a great way to produce long wave UV light. In nature, long wave UV light is present in sunlight and is not harmful to humans.
Short Wave Ultraviolet Light
There are two types of short wave UV light; filtered and unfiltered. As you can imagine, unfiltered UV lights allow a large amount of visible light through, rendering it useless for making many minerals glow. Too much visible light passes through and drowns out the “glow”. Filtered short wave UV lights on the other hand, filter out almost all visible light, allowing only shortwave ultraviolet light to pass through. These filters can be somewhat expensive which is why high quality shortwave UV...
All minerals have the ability to reflect light. As a matter of fact, that is how we humans are able to see the minerals. Whats interesting though is that some minerals have the unique ability to glow under black lights, or UV light. This special ability is called fluorescence. When light shines, these special minerals temporarily absorb some of tha...
Unfortunately, the inexpensive UV LED flashlight you bought for $5 probably isn’t going to work very well with many minerals. As I mentioned earlier, the inexpensive LED black light lamps almost always emit long wave UV light. This means that a large amount of visible light is passing through the filter, which over powers, or drowns out the actual ...
Hopefully this article has helped you understand a little bit more exactly how and why minerals glow under certain kinds of black light. Unfortunately, not all black lights are the same, and not all black lights can make minerals glow. But if you’re able to get your hands on one of these lights that were reviewed in this post, then you’ll have the ...
Longwave ultraviolet, near UV, LW UV, or UVA; Midwave ultraviolet, middle-wave, Mediumwave, MW UV, or UVB; Shortwave ultraviolet, SW UV, or UVC; Extreme ultraviolet, far UV, vacuum UV, or VUV; The notations LW, MW, and SW are most often used by minerologists, with the bands generlly centered around the mercury gas emission lines of 365nm, 311nm ...

long-wave UV, medium-wave UV, and short-wave UV. The short-wave UV range, also known as UV-C, is from around 200 to 280nm. Short -wave UV is very dangerous and will cause severe burns. Staring straight into a light source emitting this range will cause blindness. Bacteria and other germs don’t stand a chance—which is why this
Ultraviolet (UV) light is electromagnetic radiation of wavelengths of 10–400 nanometers, shorter than that of visible light, but longer than X-rays. UV radiation is present in sunlight , and constitutes about 10% of the total electromagnetic radiation output from the Sun.
Ultraviolet (UV) "light" is a type of electromagnetic radiation. UV light has a shorter wavelength than visible light. Purple and violet light have shorter wavelengths than other colors of light, and ultraviolet has even shorter waves than violet does; so ultraviolet is sort of "purpler-than-purple" light or "beyond violet" light.
Aug 10, 2016 · Ultraviolet (UV) light has shorter wavelengths than visible light. Although UV waves are invisible to the human eye, some insects, such as bumblebees, can see them. This is similar to how a dog can hear the sound of a whistle just outside the hearing range of humans. ULTRAVIOLET LIGHT FROM OUR SUN.
