87-841 50 mm Dia. Hard Coated OD 4.0 25nm Bandpass Filter; t=3.5 mm 1300nm
The 87-841 is a Bandpass Filter, specifically designed for use in optical systems requiring a narrow passband. Sourced from Edmund Optics, this filter features a circular shape with a 50 mm diameter and a thickness of 3.5 mm. The filter's primary function is to allow light transmission within a specific range of wavelengths while blocking light outside this range.
The 87-841 filter is designed for a central wavelength (CWL) of 1300nm, with a cut-on wavelength of 1287.5nm and a cut-off wavelength of 1312.5nm. This precise wavelength range is achieved through the use of hard coating on both the front and back surfaces, which is identified as EDM 87-817. This coating enhances the filter's durability and performance, making it suitable for various applications.
The filter's geometry, including its diameter and thickness, is designed to ensure efficient integration into optical systems. The 50 mm diameter provides a generous aperture, allowing for high light throughput. The 3.5 mm thickness, on the other hand, contributes to the filter's overall robustness.
