Compared with
conventional UV emitters, excimer emitters offer properties which
improve and expand the use of UV radiation in industry, preparative
chemistry, biology and medicine. The monochromatic spectrum and the
ability to select specific wavelengths allow photo-processes to be
carried out in a much more focused manner. In addition there is no
unwanted heating effect, as excimer UV emitters produce no infrared
radiation in their spectrum.

| Excimer UV Emitters |
Excimer is an
abbreviation of "excited dimer". This is essentially a pair of atoms
with 1 excited gas atom,
which are normally not bonded in the ground
state. (Xe + Xe* = Xe2* (Excimer)).
|
Noble gases and
noble gas/halogen mixtures can form excimers. The Excimer state is very
short lived.
On decomposition of the excimers, UV radiation is emitted
in a very tight, quasi monochromatic spectral range. Depending on the
choice of gas, different narrow band UV spectra are produced,
predominantly in a
single spectral line.
|
Today, there are several different
excimer combinations, which can produce UV radiation in the wavelength
range between 120 nm and 380 nm. The spectrum has no infrared component
and emitters provide the
pure UV spectrum.
|
The gas discharge is
created by a high frequency electromagnetic field. Electrodes are
therefore not
needed in the gas discharge. High power excimer emitters
are operated with water cooling to prevent
heating of the emitter..
|
| It offers two excimer versions: |
 BlueLight Compact Excimer
System |
The BlueLight
Compact Excimer System is an economical and easy-to-use solution for
applications which
require 172 nm UV radiation. BlueLight Compact is a
complete system, consisting of an Excimer lamp,
available in various
lengths and power levels, with matching power supply units.
The system is very compact, flexible in use and ready for immediate
operation. There is no need for
forced cooling. BlueLight Compact is
ideal for various applications in the laboratory and in industry.
|
| High Power Excimer System |
It offers high power
excimer irradiation units complete with power supplies and cooling
units.
Emitters for wavelengths 172 nm, 222 nm, 282 nm and 308 nm are offered
as standard irradiation units with illuminated lengths of 300 mm and 600
mm. High power excimer units are available in the power range of
450 W
to 3 kW.
