87-811 12.5 mm Dia. Hard Coated OD 4.0 25nm Bandpass Filter; t=3.5 mm 1000nm

The 87-811 is a Bandpass Filter with a diameter of 12.5 mm, sourced from the reputable optical components vendor, Edmund Optics. This filter is specifically designed for use with a central wavelength of 1000nm, making it suitable for a wide range of applications that require precise wavelength control.

The filter is constructed with a hard coating on both the front and back surfaces, denoted as 'edm 87-811'. This coating enhances the durability and longevity of the filter, making it resistant to wear and tear, and ensuring optimal performance over time.

The 87-811 filter has a thickness of 3.5 mm, which is a standard size for many optical applications. The cut-on wavelength is 987.5nm, and the cut-off wavelength is 1012.5nm, providing a narrow bandwidth of 25nm. This characteristic is particularly useful in applications where a high degree of wavelength selectivity is required.

The filter is designed in a circular shape, which is a common form factor for many optical components due to its ease of integration into various systems. It also features a Thin Lens shape, which can be beneficial in applications where minimal optical path length distortion is desired.
