Is 365 or 395 nm better?
The main distinction is that the 395 nm LED emits significantly more visible light than the 365 nm LED. The 395 nm LED emits a bright violet light, whereas the 365 nm LED emits a dull, bluish-white light (the result of residual light energy that “tails” off into the visible spectrum).
Is 365 nm UV harmful?
Because UV flashlights emitting at wavelengths 365 nm or higher are emitting in the UV-A range, they can be thought of as being less harmful than the UV-B wavelengths. Generally speaking, the overall amount of UV light emitted from a UV flashlight is also much less than what you would find outdoors on a sunny day.
What is the UV light spectrum?
UV (Ultraviolet) Light refers to the region of the electromagnetic spectrum between visible light and X-rays, with a wavelength falling between 400 and 10 nanometers.
What is the best UV wavelength?
As the chart below shows, most fluorescence is strongest in the 320-380 nm range, with a peak at 365 nm. Therefore, we would typically recommend a wavelength of 365 nm for most blacklight applications where maximum fluorescence is desired.
How many nm is UV light?
UV light covers a wavelength spectrum from 100 to 380 nm and is subdivided into three regions by wavelength: UVA (320 to 400 nm), UVB (280 to 320 nm), and UVC (200 to 280 nm) (1).
What nm is black light?
365 NM
365 NM is the standard UV light source when people refer to black light. When in doubt use one of our 365 nm black light energy for fluorescent items. Some dyes and pigments are able to absorb higher wavelength but generally speaking 365 nm is considered the generic “black light” designation.
What is the difference between 365nm and 395nm?
The main difference is that the 395 nm LED emits much more visible light than the 365 nm LED. The 395 nm LED emits a pronounced violet-colored light, while the 365 nm LED emits a dull, bluish-white light (the result of residual light energy that “tails” off into the visible spectrum).
What color is blood under UV light?
Beneath a black light, blood turns black, unless sprayed with luminol which gives it a blue-glow. Saliva, semen and urine also glow when hit with a black light.
What are the 3 types of UV rays?
What are the different types of UV radiation rays? UV radiation is classified into three primary types: ultraviolet A (UVA), ultraviolet B (UVB), and ultraviolet C (UVC). These groups are based on the measure of their wavelength, which is measured in nanometers (nm= 0.000000001 meters or 1×10-9 meters).
What is the wavelength of UVC?
200 to 280 nm
UV light covers a wavelength spectrum from 100 to 380 nm and is subdivided into three regions by wavelength: UVA (320 to 400 nm), UVB (280 to 320 nm), and UVC (200 to 280 nm) (1).
What is the most powerful UV light?
The ultra bright PowerMAX UV Blacklight Flashlight produces a powerful ultraviolet flood light effect beam that illuminates objects over 30 feet away. Powered by an industry leading 100 LED high intensity, long distance bulbs which produce 395nm wavelength UV light.
What color is 365nm?
bluish-white light
The 395 nm LED emits a pronounced violet-colored light, while the 365 nm LED emits a dull, bluish-white light (the result of residual light energy that “tails” off into the visible spectrum). Both types emit in the UV-A wavelength range and are generally capable of producing “blacklight” or curing effects.
