ULTRA VIOLET

The term “ultra violet” means “beyond violet.” In the visible part of the spectrum, wavelength decreases and the energy of the electromagnetic waves increases, so UV light has a shorter wavelength, and more energy than violet light. Wavelengths are measured in nanometers (nm), or billionths of a meter, and ultra violet wavelengths range between 10nm and 400nm. It can be classified as UV-A, UV-B or UV-C, in order of decreasing wavelength.

LAMPS FOR STERILISATION OF AIR/WATER/SURFACES

The Heraeus GoldSpot amalgam lamps are regarded as the market-leading product – primarily due to their long service life and unique Long life technology.


The extremely long-life high-performance low-pressure lamps achieve up to ten times higher UV power density compared to conventional mercury low-pressure lamps and can be used at higher ambient temperatures (up to 90°C). More-over, amalgam lamps are insensitive to temperature fluctuation.

Heraeus Long life coating

The unique Heraeus coating prevents the transmission loss of the quartz glass which is a major factor in conventional UV lamps. The result is an almost continuous sterilization effect over the entire service life of the lamp. Up to 90 percent of the UV-C output power is achieved even after 16,000 hours of operation. The Long life coating is transparent, including for 185 nm radiation.

Saving potential of amalgam lamps

Amalgam lamps can enable savings with regard to number of lamps, plant components, energy consumption and service intervals – and clearly reduce the operating costs of sterilization plants due to their high output and long life. They save energy, generate very little heat and can be used as a low-cost alternative to medium-pressure lamps. Our flyer provides a comparison of the cost effectiveness of amalgam lamps.

Ozone-generating radiation

Additional VUV radiation is emitted at a wavelength of 185 nm if the light tube is made of ozone-generating synthetic quartz glass. With the optimal combination of quartz material and lamp technology, UV output at 185 nm can even be increased to five times that of a standard low-pressure lamp.

FLOURESCENT TYPE STERILISATION LAMPS

Low Pressure mercury vapour discharge lamps consisting of a tubular glass envelope, emitting short-wave ultra violet
radiation with a radiation peak at 253.7nm for germicidal action.

The glass filters out the 185nm ozone forming line. A protective coating on the inside limits the depreciation of the
useful UV-C radiation output.

TUV lamps are used for killing or inactivating bacteria, viruses and other primitive organisms.
Typical applications include air, water and surface disinfection.

OPTICS & ANALYTICS

Modern analysis instruments need light sources of a quality that optimally supports their performance capability. Deuterium lamps, hollow cathode lamps and other light sources made by Heraeus are not only designed for long life but also for maximum precision and stability.

We cooperate closely with instrument manufacturers to develop radiation sources that precisely meet the requirements of the instruments. Production locations in Germany, the UK and China guarantee close cooperation with our customers.

Industrial non-laser applications include:

  • Rapid thermal processing
  • Water and food sterilization
  • Photographic applications
  • Ink curing/ drying
  • Sun simulation
  • Weathering

ARC & FLASH LAMPS

As the exclusive distributor of Heraeus lamps in the Sub Saharan Region, all ARC and Flash lamps are imported from Heraeus Noblelight Ltd. in Cambridge. They are especially suitable for high-power lasers or lasers with high precision requirements.

  • Automotive Welding & Cutting
  • General Cutting & Welding
  • Drilling
  • Marking/Engraving
  • Resistor Trimming
  • Diamond Processing
  • Medical and Aesthetic applications
  • Sun-simulation

Laser lamps are mercury-free gas discharge lamps used to pump solid-state lasers in many laser applications like welding, cutting and marking. They are especially suitable for high-power lasers or lasers with high precision requirements. Also for non-laser applications like IPL hair removal, ultra violet (UV) curing, sun simulation and rapid thermal processing of silicon wafers, pulsed laser lamps are increasingly used. Their main advantages in these applications are their broad spectral output and their high powers.

CURING LAMPS

UV mercury lamps are the most commonly used type of lamp for industrial UV curing and printing processes.With over 10,000 lamp types in our portfolio we offer high quality replacements for every major machine and system manufacturer. 

We can design and manufacture from just one replacement UV lamp for your system, up to large batch quantities for the most widely used types. Power ratings range from 80 watts per cm up to 400 watts per cm and we can produce lengths between 12mm and 3.9m in a range of spectral outputs.

Metal halide (MH) lamps are often used for reprography applications. They are also suited for UV curing applications that require a specially adjusted light spectrum. The term metal halide lamp is used for UV mercury lamps with added gallium iodide, iron iodide or other substances that alter the lamp’s spectral radiation. Metal halide lamps are suited for many different industrial applications such as the following: pre-press, wood finishing, curing of printed circuit board coatings, special label printing applications, curing of adhesives and resins.

The operating life of a Ultra Violet curing lamp is measured in hours of ultra-violet output, which reduces gradually throughout the life of the lamp. Standard UV curing lamps emit enough UV to cure for an average of 1000 hours. Improved production techniques and higher grade materials have enabled the production of UV lamps with operating life in excess of 1500 hours, when operated in suitable machines under optimum conditions.

200% Tested for absolute reliability! Every UV lamp is tested not once, but twice before it leaves the manufacturer. This means no surprises when you install it; it starts the first time, every time, so you have minimum down-time on your lamp changeovers.
