87-864 25 mm Dia. Hard Coated OD 4.0 50nm Bandpass Filter; t=3.5 mm 1225nm
The 87-864 is a Bandpass Filter, specifically designed with a circular base shape and a diameter of 25 mm. This filter is sourced from Edmund Optics, a reputable vendor known for their high-quality optical components. The filter features a hard coating on both the front and back surfaces, ensuring durability and longevity.
The filter's primary function is to allow light within a specific wavelength range to pass through while blocking out other wavelengths. In this case, the cut-on wavelength is 1200 nm, and the cut-off wavelength is 1250 nm, with the central wavelength (CWL) at 1225 nm. This makes it ideal for applications that require precise wavelength selection within this range.
The filter has a thickness of 3.5 mm and is shaped as a thin lens. The material ID for this filter is UVFS MAL-1965. The filter's geometry and physical data suggest that it is designed for high-precision applications that require tight wavelength control and excellent optical quality.
