The 86-991 is a 50 mm diameter Bandpass Filter, specifically designed for fluorescence applications, with a center wavelength of 448nm. This filter is sourced from the reputable optical vendor, Edmund Optics. It is characterized by its 20nm bandwidth and high optical density (OD) of 6, ensuring effective light filtration and minimal transmission outside the specified bandwidth.
The filter is constructed with a circular geometry, having a diameter of 50mm and a thickness of 2mm, making it compatible with a wide range of optical systems. The cut-on wavelength is 438nm, and the cut-off wavelength is 458nm, further emphasizing its narrow bandwidth and high selectivity.
The 86-991 filter features hard coating on both the front and back surfaces, denoted as 'edm 86-975'. This coating enhances the filter's durability and resistance to scratches and environmental factors, ensuring longevity and consistent performance.
The filter's shape is defined as a Thin Lens, indicating its suitability for use in complex optical systems where minimal optical path deviation is required. This filter is currently in stock and available for immediate purchase, as indicated by its weblink status.
