Osram Vitalux 300 Watt

The ULTRA-VITALUX lamp produces a mix of radiation very similar to
that of natural sunlight and can have the same positive effects on the
body as the sun. This blend of radiation is generated by a quartz
discharge tube and a tungsten filament. The bulb is made of special
glass which allows only the part of the output that is contained in natural
sunlight to pass through.

Because of their sun-like radiation properties, ULTRAVITALUX lamps are
used in industrial material testing, particularly for testing materials and
equipment in different environments to DIN 50 010:

• Suitability for use in the tropics
• Artificial ageing
• Weathering
• Changes in material properties, reliability or service life under
  particular climatic conditions, etc.

The total irradiance of the sun on the surface of the Earth at noon on a
sunny June day is around 1 kW/m2 (annual average solar radiation at a
latitude of 50° N is 200 W/m2). An array of 16 lamps per square metre
at a distance of about 50 cm between the bulb crown and the irradiated
object achieves a similar uniform irradiance.

ULTRA-VITALUX lamps are used for curing plastics. Modern plastics are
cured by exposure to UV radiation. Special photo initiators cause
polymerisation in plastics when the plastics are exposed to UV radiation.

The advantages of the process are as follows:

• Only one substance is needed. There is no need for mixing and
  dosing
• Under normal indoor lighting, processing times can be almost any length
• Pot times are no problem
• Rapid curing with UV radiation
• Clean processing in industry, workshops and DIY

ULTRA-VITALUX lamps are suitable for the exposure of photo-resists.
In electronics the pattern of printed circuits is transferred by means of
UV exposure onto a photo-resistive layer. After development, the board
can be etched, leaving only the conductor paths.

The advantages of the process are as follows:

• Simple handling
• High UV content
