The 35-889 is a 50 mm diameter Bandpass Filter, designed and manufactured by Edmund Optics, a leading global supplier of optical components. This filter is specifically engineered for applications requiring a narrow passband, with a central wavelength (CWL) of 285nm. The filter features a hard coating on both the front and back surfaces, ensuring durability and resistance to environmental factors.
The 35-889 filter is designed with a base shape of a Circular Thin Lens, making it suitable for a wide range of optical systems. The filter's geometry includes a diameter of 50mm and a thickness of 3.5mm, providing excellent optical performance and minimal distortion. The physical data of the filter specifies a cut-on wavelength of 280nm and a cut-off wavelength of 290nm, ensuring precise filtering of the desired light spectrum.
The coating on the filter is Edmund Optics' proprietary EDM 35-875, which is a broadband anti-reflection coating. This coating is designed to reduce surface reflections and increase transmission, enhancing the overall performance of the filter. The 35-889 filter is currently in stock and available for immediate shipping, as indicated by its weblink status.
