| The UV curing industry has
developed a growing demand for light sources with short wave
UV radiation down to 250nm. Important applications are photo
resist coatings in wafer production, DVD assembly, and curing
of UV adhesives with tack free surfaces.
While UV lamps which are specially designed
for UVC are very costly and generate ozone, the SUV-DC-P "Deep
UV" uses an ozone free super pressure mercury lamp.
It has been proved that conventional super pressure mercury
lamps deliver sufficient UVC radiation for most spot curing
applications. However, in order to deliver this UVC radiation
all optical components of the SUV-DC-P underwent an upgrading
to top level UVC grade materials. A critical component
is the Liquid Lightguide. The newly developed Series 250
Liquid Lightguide delivers the UVC radiation at a transmission
level far superior to quartz fiber bundles and virtually
free of degradation. The result is a moderately priced
ozone free UVC spot curing system.
The SUPERLITE SUV-DC-P "Deep UV" has the same outstanding
features and lamp life characteristics as the standard SUV-DC-P
lightsource. However, the optical filter was adapted to the
new spectrum: the filter is open in the UVC, UVB, and UVA
range, blocking off the entire visible radiation except for
a narrow red band which serves as pilot light. This ensures
optimal heat protection for the substrate.
