86-675 50 mm Dia. Hard Coated OD 4.0 25nm Bandpass Filter; t=3.5 mm 950nm

The 86-675 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 950 nm, making it ideal for applications that require precise wavelength selection within this range.

The filter is constructed with a hard coating on both the front and back surfaces, denoted as 'edm 86-651'. This coating enhances the filter's durability, making it resistant to scratches and other forms of wear and tear. The filter's thickness is 3.5 mm, providing sufficient structural integrity for most optical applications.

The 86-675 features a Cut-On wavelength of 937.5 nm and a Cut-Off wavelength of 962.5 nm. This 25 nm bandpass ensures a high level of wavelength selectivity, reducing unwanted out-of-band transmission. The filter's geometry is defined by its circular shape and 50 mm diameter, making it compatible with a wide range of optical systems.

The filter's physical data, including the Cut-On, Cut-Off, and Central Wavelength, are all precisely controlled during the manufacturing process. This ensures consistent performance across all units, a critical factor for applications that require high levels of wavelength accuracy and stability.
