86-989 50 mm Dia. Hard Coated Fluorescence Bandpass Filter; t=2 mm 357nm
The 86-989 is a Bandpass Filter, specifically designed for Fluorescence applications, available from Edmund Optics. This filter, with a diameter of 50 mm and a thickness of 2 mm, is a circular component made from UVFS material, identified as MAL-1965.
The filter's primary function is to allow light within a specific wavelength range to pass through while blocking other wavelengths. The 86-989 is designed to pass light at a central wavelength (CWL) of 357nm, with a bandwidth of 44nm. This makes it ideal for applications that require the selective transmission of light in this wavelength range.
The filter's cut-on wavelength is 333nm, and the cut-off wavelength is 381nm. This means that it begins to transmit light at 333nm and stops transmitting at 381nm, effectively filtering out any wavelengths outside this range.
The 86-989 is coated on both the front and back surfaces with EDM 86-973, a hard coating that enhances the filter's durability and performance. The filter's shape is that of a Thin Lens, which can be beneficial in certain optical systems.
