86-674 50 mm Dia. Hard Coated OD 4.0 25nm Bandpass Filter; t=3.5 mm 900nm

The 86-674 is a Bandpass Filter with a diameter of 50 mm, sourced from the reputable optical components vendor, Edmund Optics. This filter is specifically designed for use with a central wavelength of 900nm, making it suitable for applications that require precise filtering within this range.

The filter is constructed with a thickness of 3.5 mm, providing durability and stability during operation. It features a hard coating on both the front and back surfaces, denoted as 'edm 86-650', which enhances its resistance to wear and tear, thereby extending its lifespan.

The Bandpass Filter is designed with a Cut-on wavelength of 887.5nm and a Cut-off wavelength of 912.5nm. This specificity ensures that only light within the desired wavelength range is passed, while effectively blocking out unwanted wavelengths. The Cut-on and Cut-off wavelengths are crucial parameters in determining the filter's performance and are carefully controlled during the manufacturing process.

The filter's geometry is defined by its circular shape and a diameter of 50 mm, making it compatible with a wide range of optical systems. The Base Shape is 'Circular', and the Material ID is 'uvfs mal- 1965', providing additional information for material identification and selection.
