88-573 50 mm Dia. Hard Coated OD 4.0 10nm Bandpass Filter; t=3.5 mm 440nm

The 88-573 is a Bandpass Filter, specifically designed for use in optical systems requiring a narrow bandwidth transmission. This filter, offered by Edmund Optics, features a circular shape with a diameter of 50 mm and a thickness of 3.5 mm. The filter's primary function is to allow light within a specific wavelength range to pass through while blocking other wavelengths.

The 88-573 Bandpass Filter has a central wavelength (CWL) of 440nm, which is the wavelength where the filter's transmission is at its maximum. The filter's cut-on wavelength is 435nm, and the cut-off wavelength is 445nm. This means that the filter begins to transmit light at 435nm and stops transmitting at 445nm, effectively creating a 10nm bandwidth.

The filter is made from UVFS Mal-1965 material, a common choice for optical filters due to its excellent optical properties. The front and back surfaces of the filter are coated with EDM 88-567, a hard coating that provides enhanced durability and resistance to scratches and other forms of damage.

This filter is designed to be used in thin lens configurations, making it suitable for a wide range of optical applications. The filter's weblink status is valid and in stock, indicating that it is readily available for purchase and use in your optical systems.
