87-798 25 mm Dia. Hard Coated OD 4.0 25nm Bandpass Filter; t=3.5 mm 975nm

The 87-798 is a Bandpass Filter, specifically designed for applications requiring precise wavelength selection. This filter, sourced from Edmund Optics, features a circular shape with a diameter of 25 mm and a thickness of 3.5 mm. The filter's primary function is to transmit light within a specific range of wavelengths while blocking other wavelengths.

The 87-798 filter is designed to transmit light at a center wavelength (CWL) of 975 nm, with a cut-on wavelength of 962.5 nm and a cut-off wavelength of 987.5 nm. This specificity in wavelength transmission makes it ideal for applications that require narrow-band light, such as fluorescence microscopy, spectroscopy, and other laser-based systems.

The filter is made from UVFS Mal-1965 material, a common choice for optical filters due to its excellent transmission characteristics and durability. The front and back of the filter are coated with EDM 87-786, a hard coating that enhances the filter's resistance to scratches and other forms of damage, ensuring longevity and reliability in operation.

The 87-798 filter is currently in stock and available for immediate use. For more information, including pricing and detailed specifications, please refer to the provided weblink.
