86-988 25 mm Dia. Hard Coated Fluorescence Bandpass Filter; t=2 mm 676nm
The 86-988 is a Bandpass Filter, specifically designed for Fluorescence applications, available from Edmund Optics. This filter, with a 25 mm diameter and a thickness of 2 mm, is a circular component made of UVFS Mal-1965 material.
The filter's primary function is to allow light within a specific wavelength range to pass through while blocking other wavelengths. The 86-988 is designed to pass light in the 676 nm range, with a bandwidth of 29 nm. This is facilitated by the cut-on wavelength at 658 nm and the cut-off wavelength at 694 nm.
The filter's front and back surfaces are coated with EDm 86-980, a hard coating that enhances the filter's durability and performance. The filter's shape is that of a Thin Lens, which suggests it may have some light bending properties.
According to the vendor's information, this filter is in stock and available for immediate purchase. The item's catalog number is 86-988, and it can be found on the Edmund Optics website at https://www.edmundoptics.com/p/676nm-cwl-25mm-dia-29nm-bandwidth-od-6-fluorescence-filter/29400/.
