Dr. Fischer Microscope & Analyser Lamps
Many experimental and analytical techniques in medicine and research depend on good, colourneutral and reliable light. In addition, the light source must only emit a minimum of heat but still provide sufficient light
Whether it is a blood analyzing device or an endoscope, the quality of the knowledge and results also depends causally on the quality of the Dr.Fischer lamps. We are well aware that we have a serious responsibility here.

Dr. Fischer Dental Lamps
Dental lights with special lamps are required while seeking evidence or making a diagnosis and treatment at dental practices.
Reliable lamps are also the basis of safe and skillfully-crated work in dental laboratories. Bright, glare-free light is a necessity when models are being created.

Dr. Fischer UV Lamps
In 2011, Dr. Fischer took over the medium pressure UV Lamps production equipment from Philips and started the production center at France. The integration of Philips’ entire production activities in UV and of all its employees means that Dr. Fischer Group in Pont à Mousson now has comprehensive competences for special UV solutions – from research over development, quality and production to marketing and sales.
UV Lamps are used for:
Copying with UV sensitive materials | Curing lacquers/paint/ink |
Curing glue/resin | Diazo copying |
Polymerization of polyester | Printed circuit boards exposure |
Platemaking (offset printing) | Copy board lighting |
Copying | Material durability testing |
Innovative UV applications will become increasingly important in many industrial processes: polymer curing, photosensitive materials exposure and many others.
Dr. Fischer HPM Lamps
HPM Diazo lamps emit in the Diazo range (230 – 450 nm) and are optimized for UVA radiation. Being similar to HPA lamps, HPM lamps are designed to meet the special spectral demands of reprography, photochemical applications and the use of Diazo colors. The lamp spectrum has been modified by adding additives and adjusting the mercury content to generate exactly those spectral lines needed to cure Diazo colors. They are therefore ideal for high-quality, large-format printing and plotting applications in the architectural and engineering industries.
In addition, HPM Diazo lamps provide a high radiant efficiency and high arc stability for cost-efficient and reliable usage. They provide the ideal light source for contact copying of images from transparent film to UV-sensitive carriers such as fi lm, offset plates, printed circuit boards and microfilms. They are also ideal for photochemical process applications such as the UV-curing of glues, resins and pigmented lacquers.
Sl. | Model | Volts | Wattage |
1 | HPM 12 | 120 V | 460 W |
2 | HPM 13 | 125 V | 1000 W |
3 | HPM 15 | 245 V | 1950 W |
4 | HPM 17 | 243 V | 2000 W |
Dr. Fischer XOP Xenon Lamps
XOP Xenon lamps are linear lamps equipped with a special cable connection that prevents arcing. Straight XOP lamps have a diameter of 12 mm and an overall length of 241-698 mm, depending on wattage. The spectrum of their radiation output is, like that of all xenon lamps, nearcontinuous, ranging from about 200 to 1000 nm. Due to this it simulates sunlight very closely. The color temperature is 5600 K. XOP Xenon lamps are used either in continuous or pulsed mode (stroboscopy).
Depending on the application XOP lamps might need forced-air cooling. The lamps do not generate any ozone. Since they emit UV light, they must be screened to protect the eyes and skin. Care must be taken to avoid overexposure of eyes and skin. In view of the high starting voltage, the lamp holder and cabling must be insulated from the luminaries. The burning position is universal.
Sl. | Model | Volts | Wattage |
1 | XOP 7 – OF 1CT/4 |
207 V | 650 W |
2 | XOP 15 – OF 1CT/6 |

Dr. Fischer HPA Lamps
Ved Group has for the last 20 years been the leader in the distribution of Philips Solarium lamps. In 2009 iSOLde Licht GmbH took over the manufacturing of the Philips tanning range of lamps and continues the long success story of the Philips brand into the future.

Dr. Fischer Infrared Halogen Lamps for Infrared Cabins & Saunas
Dr. Fischer Vitae infrared halogen lamps are designed for body relaxation applications such as infrared cabins. These lamps are designed for creating well-being experiences such as laying into infrared cabins or saunas. These highly technological lamps give health and beauty centers the opportunity to offer an innovative, rapid and convenient service. Dr. Fischer Vitae infrared halogen lamps have numerous benefits for body heating like a warm feeling with an efficient, direct and gentle heat. The lamp emissions reach the subcutaneous layer of the skin (see graph: Depth of penetration into the skin), where heat is dissipated more efficiently. This gives a more diffuse and pleasant warming effect. Dr. Fischer lamps provide direct body heating, matching the characteristics of the skin.
