Vacuum Technology for Special
Projects
 DREVA LAB 450
specific and adaptable
This
plant is designed specifically for the purpose of depositing thin films in
optics, electronics, and mechanical engineering. Its extensive technological
equipment enables multivalent utilisation in ever changing areas of application,
notably in experimental research and small scale production.
DREVA THERM 400
small and
versatile
This plant is designed specifically for the purpose of
glowing, tempering, soldering, and melting in a vacuum environment. Varying heat
application enables temperatures from 400°C to 1400°C.
Experimental research
and small production runs are the main fields of application.
DREVA CLEAN 350 und DREVA CLEAN
450
small and highly efficient
Small plants for
substrate cleaning through use of a plasma source - Degreasing without chemical
solutions - Fast degreasing of hollow spaces and internal areas. Sterilisation
of devices and components - Drying at low temperatures is possible. Relevant
fields of application are research, teaching, and small scale
production.
DREVA DRY 350
fast and
thorough
Small plant for gentle drying of heat sensitive items. Low
temperature generation from plasma source. This plant guarantees fast drying of
hollow spaces and internal areas. Fields of application are research and
teaching, as well as small scale production.
DREVA OPT 400 und DREVA OPT
550
small and effective
These are system versions of
the DREVA ARC 400 plant, specially developed for the optics field. They are
technically designed to be used as laboratory or production plants for the
coating of lenses, prisms through to optical components with spectrally assigned
film systems. Coatings are effected by electron beam evaporation or sputter
sources. Operation control can be either manual or automatic. Experimental
research and small scale production are the relevant fields of
application.
PLASMA 550 und PLASMA 1058
reducing costs and protecting the environment
Simple plants
of variable sizes for the plasma treatment of substrates made of plastic and
other temperature sensitive materials. An air or gas mixture is ionised inside
the vacuum chamber, using a plasma source, thereby releasing radicals and UV
radiation. The plastic surface is made passive, thus enabling the smoothing of
the surface by basic lacquering before coating. Heat intrusion into the
materials is negligible. The plasma works from the bottom to the top, and the
plant design, with its movable lower part and fixed upper part, has taken that
into account. The structure is problem-free and operator
friendly.
ASTA 2400
high
precision and economical
A simple on-floor optics plant for the
special coating of astronomic mirrors with diameters up to 2400 mm. The vacuum
chamber consists of two parts. The horizontal, mobile part of the chamber
contains the substrate carrier mounted on ball bearings. The fixed part of the
chamber contains all the devices that are necessary for the coating process. The
whole unit is mobile. Economies are achieved through the on-the-spot coating
facility for large telescopic mirrors, which frequently require re-coating.
Relevant application areas are astronomic observatories.
