Biomedical filter

In order to ensure the accuracy of diagnosis and analysis, biomedical filters need high bandwidth and wavelength stopping depth. It is the core component of medical devices, and only part of the light passing through the special wave band is allowed. The coating of biomedical filter is ion assisted coating. The unique coating treatment makes the filter wavelength accurate and durable. It can ensure that the filter has high transmittance and cut-off depth, and the bandwidth tolerance is controlled within plus or minus two nanometers

because the wavelengths of light passing through all points on the same filter are consistent, and they are accurately positioned by the optocoupler. After the light intensity converges, it will not be affected by the component error of the equipment itself. The generated energy is high and the voltage range is relatively strong. When the mainstream light intensity, the influence of other stray light is very weak, can be ignored, the error is very small, and the light is stable, so the detection is relatively stable. The range of biomedical filters ranges from simple colored glass to highly designed interference filters, which selectively allow the passage of certain specific wavelengths of light while blocking unwanted wavelengths。
