single Chip LED`s without thermal wavelength shift

Replace your Xenon bulp with XenoLED375, Gold LED

or bulp for the NIR range with SWIR 2835 LED, NIR LED IR2000

or a Xenon flash with the UV A-B-C LED 3535, blue UV A-B LED , D270

Many surfaces as for example paper or clothes contain luminescence colors them, animated in the violet and/or close ultraviolet area of the electromagnetic spectrum, in the visible area of the electromagnetic spectrum shine. Light-emitting diodes the white light emit radiate not enough in the violet and/or close ultraviolet area of the spectrum to receive a natural colour impression of these surfaces for the viewer. If several light-emitting diodes are used they in the visible one as well as in the violet and/or close ultraviolet area of the spectrum these surfaces irradiate at the same time changed themselves, however, e.g., by different temperature drifts of the light-emitting diodes, the spectrum of the single light-emitting diodes and with it also the colour impression for the viewer. Also caused, particularly on short distances between the lighting and the surface, the distance between the multi colour light-emitting diodes lead to different colour effects and brilliant effects.

Now by means of XenonLED375  you got the whole visible spectral range from ultraviolet 370nm up to the infrared 1000nm one shines. Ideally suitably for colour measuring instruments and spectroscopic uses or lighting like the daylight are.

If you need not so much power at 430nm but much more about 500nm than take the GoldLED375. Ideally suitably for spectroscopic analytic of clear and turbid substance.

Replace your Xenon flash with the UV A-B LED D270  you got the whole UV-A spectral range and a part form UV B and VIS in the spectral range from 270nm up to 450nm . Ideally suitably for spectroscopic application.

With the blue UV A-B LED C270 and the GoldLED you can cover the spectral range from 270nm up to 1050nm. Ideally suitably for spectroscopic application.

NIR:

The SWIR 2835 LED emits between 460nm to 1850nm. Suitable as a replacement for incandescent lamps for transmission measurements of emulsions or biological tissue. Unlike an incandescent lamp, there is no drift in wavelength intensity (Wien shift). Often samples have different scattering coefficients. If a Wien shift occurs at the same time, both effects are often difficult to distinguish. The SWIR 2835 LED on the other hand is frequency stable and has a longer lifetime than an incandescent lamp.

The NIR LED IR2000 emits between 900nm and 2000nm. Ideal for spectroscopic analysis of aqueous solutions.
