ENHANCED METAL ARC LAMPS

EmArc® lighting technology is the culmination of a dedicated effort to bring together the
inherent advantages of a number of gas discharge sources into a single light source.
The technology equates to a critical blending of rare gas and metal additives to derive,
in a single source, many of the key properties and benefits of stand alone Xenon, Metal
Halide and Mercury lamps.
EmArc light sources are a series of highly efficient, Enhanced Metal Arc, DC gas discharge
lamps designed for use in medical, scientific, industrial and entertainment settings.
EmArc lamps are a progressive step ahead in lighting technology possessing features
that offer advantages to an array of users for imaging, fiber optic and other important
optical applications.
EmArc lamps have geometric designs which enable alignment in dichroic visible light or
UV specific coated reflectors facilitating use in numerous applications like lighting for
minimally invasive surgery, curing of light sensitive resins and adhesives and, dental
whitening procedures. EmArc versatility enables its use in a number of entertainment
applications including searchlights, followspots, special effects and automated fixtures.
EmArc lamps are comparable to Metal Halide sources in luminous efficacy but with 2
times to 5 times the life. A correlated color temperature like that of Xenon at 6000K, with
very small arc gap sizes, but with 2 times the luminous efficacy of Xenon lamps.
EmArc technology differentiates itself as a new family of discharge lamps.
High luminance at tip of cathode
with DC arc discharge
APPLICATIONS:
• Medical Fiber Optics for Endoscopy or Headlight Illumination
• Biotechnology / Micro-Array
• Industrial UV Curing
• Machine Vision
• Cosmetic Dentistry
• Projection / Entertainment
• Microscopy
• Entertainment
The construction of EmArc arc tubes, electrodes and precise
filling technique provide the environment for the tightly confined
plasma arc discharge. EmArc light output over time exceeds that of
typical DC Xenon and AC short-arc Metal Halide lamps.
