Light sources

A light source is a separate cold light projector that generates light using powerful lamps; the light then exits at the sheath and illuminates the cavity to be inspected. Lamps include LED, halogen, XENON, Solarc®, and incandescent lamps.

In 1960, Dr. Karl Storz invented the cold light source. Since that time, light has been generated outside of the endoscope and transmitted to the tip through high quality fiber-optic light guides to minimize the heat generated at the endoscope.

The suitability of a light source depends on the type of endoscope used. Therefore, we offer various light sources at different power levels as well as portable, battery-operated cold light projectors. A range of power levels are available, from 5W LED to 300W Xenon high performance light sources. Bright light is a key determinant of image quality. Our powerful, high quality light sources are therefore a decisive factor in generating informative endoscopic images.

Battery-powered LED light source

The battery-powered LED light source is available in a disposable battery version as well as a rechargeable battery version. It features the extraordinarily high light intensity of 100,000 Lux and produces absolutely white light. Other major advantages are the long operating life of LEDs (up to 50,000 hours) and a run time of more than 120 minutes. The battery-operated LED light source is compatible with almost all KARL STORZ endoscopes and connects directly to the light connector. Therefore, no light cable is required.

Adjustable battery-operated LED light source

The universal design of the newly developed, battery-operated, adjustable LED light source allows it to be connected to all established KARL STORZ borescopes, flexoscopes, and autoscopes (with diameters of up to 4.2 mm). To ensure optimal user comfort, the new LED light source can be adapted to meet individual needs and is therefore suitable for both right-handed and left-handed users.

The very powerful 3 Watt light source is available with infinitely veriable light intensity. With its 5700 Kelvin color temperature (daylight), the light source supports true-color display of objects. Maximum light intensity also allows the illumination of larger objects. At maximum light intensity, the new light source has an average operation time of approx. 60 minutes.
