It works in an infrared light region (instead of Nd:YAG laser). It's one of the most advanced photo-coagulator for every clinical specialty. It enables you to adjust a precise depth of coagulations. The process is painless, bloodless, without any smell and smoke. Principle of operation: The infrared contact coagulator consists of an infrared radiation source, a rigid lightguide curved at the end at which the light emerges, and a tissue contact surface or tip made from a TeflonŽ polymer that is transparent to infrared and does not adhere to the tissue. A low-voltage tungsten-halogen lamp produces the beam that is focused into the lightguide. Through this applicator the radiation is delivered to the tissue where it is converted into thermal energy causing the process of coagulation. The red light and infrared leakage radiation is allowed to escape outside through the red lamp housing, thus preventing the coagulator from overheating and making it unnecessary to provide an expensive cooling system. The optimal amount of energy to be transferred into the tissue can be pre-set exactly by means of a timer and reproduced at all times. The ergonomically designed applicator, fitted with a hand-operated switch and supplied with low voltage be means of a flexible lead, enables the doctor to work in a simple and convenient manner. The operation of the device is very simple - it is enough to press the switch on the hand applicator after pre-setting the time of irradiation. The typical pulse length of single flashes vary from 0.5 up to 3 seconds resulting in light penetration up to 3mm into the soft tissue.
