What is better 365nm or 395nm?
What is better 365nm or 395nm?
The main difference is that the 395 nm LED emits much more visible light than the 365 nm LED. In other words, 395 nm LEDs don’t emit at only 395 nm. The 395 nm LED emits strongest at 395 nm (as defined by the term peak wavelength), but it also emits quite a bit of energy at 400 nm, and even 410 nm.
What does NM stand for in UV light?
Ultraviolet (UV) radiation occupies the portion of electromagnetic spectrum from 100 to 400 nanometers (nm).
Which type of UV radiation is most harmful?
UVC rays
UVB rays, which affect skin’s top layer, cause skin cancer and most sunburns. Although UVA and UVB rays pose the greatest risk for sun damage, people who work with welding torches or mercury lamps may be exposed to UVC rays, the most dangerous type of UV radiation.
Does 254 nm produce ozone?
Ozone is produced from UV light wavelengths between 100 and 240 nm. These lamps will produce UV light with two peaks in the UV light band, one at 254 nm, and another at 185 nm. The 185 nm light is what is referred to as an “ozone producing” lamp, while the 254 nm light is referred to as a “germicidal” lamp.
Can UVC pass through wood?
UV is easily shielded by opaque materials such as metal, wood, and cardboard; polycarbonate material is also a good UV shield.
What is the difference between 365 nm and 395 nm UV lights?
Both 365 nm and 395 nm options are within the UV-A wavelength range. Generally speaking, UV-A lights are useful for creating and observing fluorescence effects, as well as for plastics and paint curing. UV-A wavelengths are safer when compared to stronger UV-B and UV-C rays.
Why is my 365 nm LED light bluish?
When illuminating a 365 nm LED, however, you will likely notice a dull, bluish-white color emitted. This is caused by visible light “leakage” where minuscule but visible amounts of visible wavelength energy (i.e. white light) are also emitted.
What kind of led do we use for UV lights?
We use pure professional LEDs for our UV lights in the 365nm and the other higher ranges. We are the place where you can buy the best and the highest quality UV LEDs and black lights. Our special long wave 365 nm black lights are used for inspections, finding cracks and leaks, UV Curing of adhesives and resin, just about anything.
What is the best UV light for Black Light Inspection?
365 nm UV Black Lights for curing and NDT inspections. 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.
