Laser Safety Filters

In ophthalmology instruments, laser safety filters block the therapy laser with high optical density, while showing a high transmittance for the image of the patient's eye background. A sophisticated filter design with narrow blockband and balanced transmission level over the full visible range optimizes color rendering. The beamsplitter controls transmittance and reflectance for both therapy and target laser. The hard-coated filters are longterm stable and available in flexible dimensions.
