87-827 25 mm Dia. Hard Coated OD 4.0 25nm Bandpass Filter; t=3.5 mm 1200nm

The 87-827 is a Bandpass Filter, specifically designed for applications requiring a narrow passband. 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 87-827 filter has a cut-on wavelength of 1187.5 nm and a cut-off wavelength of 1212.5 nm, with a central wavelength (CWL) of 1200 nm. This precise wavelength range makes it ideal for applications that demand high spectral specificity. The filter is made from UVFS Mal-1965 material, ensuring durability and reliability.

The filter's coating is another notable feature. Both the front and back surfaces are coated with EDM 87-815, a hard coating that enhances the filter's longevity and resistance to wear and tear. This coating also aids in maintaining the filter's specified wavelength transmission characteristics over time.
