KUALA LUMPUR, May 20 -- Optics Balzers AG has further developed optical dielectric filters in the UV spectrum as short-wave light, ranging from 100 to 400nm in the UV spectrum, with the ability to fight pathogens.
In medical fields, this property is commonly used to combat germs, bacteria and viruses. In fact, studies have shown that when irradiated with short-wave UV-C light, more than 95 per cent of viruses become ineffective.
Short-wave light is also used in virological diagnostics. Antibodies are marked with a fluorochrome, and when stimulated by a defined UV radiation, can then be visualised. Specially matched optical filters are used to separate excitation and emission wavelengths.
The SP270 short pass filter from Optics Balzers shows the characteristic spectral course of a corresponding filter for the excitation of fluorophoric substances. The highest possible transmission rate is guaranteed, with a pass range of around 270nm.
The company’s optical filters, which enable the excitation and detection of signals in the UV range, can be adapted to specific substances. Based on the appropriate filters, a wide range of relevant information from the UV spectrum can be obtained for further medical diagnosis.
