Nichia NCSU275 UV SMD-LED with PCB (10x10mm), 350mW, 385nm
Nichia is one of the largest LED manufacturers in the world and inventor of the blue (and thus also white) light emitting diode. The innovative Nichia research department is a pioneer when it comes to efficiency and establishes records on a regular basis.
Durability, brightness and homogeneity are among the major strengths of the Nichia brand. Furthermore, the fine selection allows greater added value for professional processing.
The Nichia SMD LEDs in the range UV light can be used for a wide range of applications. The NCSU 275 is available with three different wave lengths. At 405nm wavelength the Nichia LED reaches a power of 370mW.This UV LED is only suitable for use in industrial applications.
Warning: invisible light, the LED constitutes a danger for the eye even at short-term radiation. Please consult our employees for advice on this product before ordering!

Actinic UV danger for eyes and skin
Ultra violet radiation in the wavelength range of 200-400nm may cause inflammation of the cornea as well as a UV erythema (sunburn) of the skin. The biological effectiveness of the UV radiation varies in the stated wavelength range and is described with the spectral response function (weighting scale) SUV.
UV-A danger for the eyes
Ultra violet radiation in the wavelength range of 315-400nm (UV-A) is for the most part absorbed by the eye lens and may cause UV cataracts (clouding of the lens of the eye).

The dominant wavelength
indicates the perceived colour of a source which is not monochromatic but in the CIE colour space. Most actual LEDs are near the pure colour curve but not on it. When connecting and extrapolating the points W (white) and P (sample), the intersection with the colour curve yields the dominant wavelength. The dominant wavelength can further be explained via the spectrum. After assessing the spectrum of the source using the V(λ) curve, the spectral centroid is determined. The dominant wavelength provides the most accurate information about the perceived colour of a source.
