The 980 nm laser is a laser machine used to treat vascular problems, such as varicose veins or dilated blood vessels. It emits a beam of light with a wavelength of 980 nm, which is ideal for absorption by vascular cells containing porphyrin, a substance present in blood vessels. When the laser beam reaches these cells, it is absorbed and converted into heat, which causes the targeted vascular cells to coagulate and be destroyed. Over time, these cells are naturally eliminated by the body, which leads to improvement in vascular problems. The 980 nm laser is used to target and selectively treat vascular cells with its specific absorption, helping to reduce problems with dilated blood vessels or varicose veins.
