87-881 50 mm Dia. Hard Coated OD 4.0 50nm Bandpass Filter; t=3.5 mm 1425nm
The 87-881 is a 50 mm diameter Bandpass Filter, designed and manufactured by Edmund Optics. This filter features a hard coating on both the front and back surfaces, ensuring durability and longevity. The filter's base shape is circular, and it is made from UVFS Mal-1965 material, a common choice for optical applications due to its excellent transmission properties.
The filter's primary function is to allow light within a specific wavelength range to pass through while blocking other wavelengths. In this case, the 87-881 is designed to pass light with a central wavelength (CWL) of 1425nm. The cut-on wavelength is 1400nm, and the cut-off wavelength is 1450nm, providing a relatively narrow bandwidth of 50nm. This makes it ideal for applications where a specific wavelength needs to be isolated or emphasized.
The filter has a thickness of 3.5mm, which is typical for this type of component. It is shaped as a thin lens, which can be beneficial in certain optical system designs. The 87-881 is currently in stock and available for immediate purchase, as indicated by its weblink status.
