87-807 50 mm Dia. Hard Coated OD 4.0 25nm Bandpass Filter; t=3.5 mm 825nm
The 87-807 is a Bandpass Filter, specifically designed with a center wavelength of 825nm, sourced from the reputable vendor, Edmund Optics. This filter is characterized by a circular shape, with a diameter of 50mm and a thickness of 3.5mm, making it suitable for a wide range of optical applications.
The filter is constructed from UVFS Mal-1965 material, a choice that enhances its performance and durability. It features hard coating on both the front and back, specifically EDM 87-783, which further improves its resistance to wear and tear, ensuring longevity and reliability in operation.
The 87-807 filter is designed with precise cut-on and cut-off wavelengths, specifically 812.5nm and 837.5nm respectively. This ensures that only the desired wavelengths are passed, while unwanted wavelengths are effectively blocked. The cut-on and cut-off wavelengths, along with the center wavelength, are carefully controlled during the manufacturing process, ensuring high precision and accuracy in the filter's performance.
The filter is designed in the shape of a thin lens, which not only enhances its optical performance but also makes it compatible with a wide range of optical systems. The 87-807 filter is currently in stock and available for immediate use, as indicated by its valid weblink status.
