Photomedicine uses special optical radiation sources for therapeutic, diagnostic, endoscopic, illumination and dental curing purposes. Gigahertz Optik GmbH produces a wide range of measuring instruments like photomedicine meters that measure the intensity and efficacy of these sources. There follows some example applications using Gigahertz Optik GmbH products.

Pulsed Excimer-Laser Phototherapy Dosimetry
Phototherapy with narrowband UVB (NB-UVB) radiation is the preferred treatment method for many skin conditions, such as psoriasis, vitiligo, and atopic dermatitis. Low-pressure fluorescent lamps with emission at 311nm are commonly used. However, excimer lamps and lasers offer a high intensity alternative with emission at 308nm. In particular, pulsed excimer lasers enable targeted therapy with higher doses of UVB light resulting in fewer treatment sessions. The ability to target specific areas enables high doses of therapeutically effective monochromatic UVB light while leaving healthy skin unexposed and protected, thereby lowering the risk of premature skin aging and carcinogenesis.
Integrating Sphere for Total Flux of Radial Emitting Fibres used for Photodynamic Therapy
Photodynamic therapy (PDT) can be used to treat certain types of cancer as well as some skin and eye conditions. In PDT abnormal cells are destroyed by the use of light-sensitive medication, known as photosensitizers, in conjunction with a suitable light source. Typically, the activation spectrum of the photosensitizer falls within the 630nm to 850nm wavelength range. Individually, the photosensitizer medication and light source are harmless, but when the medication is exposed to the light in the presence of tissue oxygen, it activates and causes a reaction that damages the nearby cells.
