87-813 12.5 mm Dia. Hard Coated OD 4.0 25nm Bandpass Filter; t=3.5 mm 1100nm
The 87-813 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 (CWL) of 1100nm, making it ideal for applications that require precise wavelength selection within this range.
The filter is hard coated on both the front and back surfaces with the EDM 87-813 coating, enhancing its durability and performance. The cut-on wavelength is 1087.5nm, and the cut-off wavelength is 1112.5nm, providing a narrow bandwidth of 25nm. This characteristic is crucial in applications where stray light needs to be minimized, such as in spectroscopy or laser systems.
The filter is shaped as a thin lens, which can be beneficial in optical systems where compactness and minimal weight are desirable.
