86-946 12.5 mm Dia. Hard Coated OD 4.0 50nm Bandpass Filter; t=3.5 mm 875nm

The 86-946 is a Bandpass Filter with a diameter of 12.5 mm and a thickness of 3.5 mm, designed for use in optical systems where precise wavelength selection is required. This filter, sourced from Edmund Optics, features a center wavelength of 875nm, making it ideal for applications that necessitate the isolation of specific wavelengths around this region.

The filter is hard coated with a durable coating on both the front and back surfaces, denoted as 'edm 86-946'. This coating enhances the filter's durability and resistance to environmental factors, ensuring reliable performance even under demanding conditions. The cut-on wavelength is 850nm, and the cut-off wavelength is 900nm, providing a narrow bandwidth that aids in the rejection of unwanted wavelengths.

The 86-946 is designed in a Thin Lens shape, which is beneficial for applications where space is a constraint. It is made from UVFS Mal-1965 material, a common choice for optical filters due to its excellent optical properties. The filter's geometry, combined with its material and coating, makes it a versatile component for various optical systems.
