87-820 12.5 mm Dia. Hard Coated OD 4.0 25nm Bandpass Filter; t=3.5 mm 1450nm
The 87-820 is a Bandpass Filter with a diameter of 12.5 mm and a thickness of 3.5 mm, sourced from the reputable vendor Edmund Optics. This filter is specifically designed for a central wavelength of 1450nm, with a cut-on wavelength of 1437.5nm and a cut-off wavelength of 1462.5nm.
The Bandpass Filter is a type of optical filter that allows only a specific range of wavelengths to pass through while blocking others. This particular model has a 25nm bandpass, ensuring a narrow and precise range of transmitted wavelengths around the central wavelength of 1450nm.
The filter is hard coated on both the front and back sides with the EDMP 87-820 coating. This coating enhances the filter's durability and performance, making it suitable for various applications.
The filter's geometry is defined by its thin lens shape, and it is available in the UVFS MAL-1965 material. The filter's physical data, including its cut-on, cut-off, and central wavelength, are meticulously calibrated to ensure accurate and reliable performance.
