84-756 50 mm Dia. Hard Coated High Performance OD 4.0 Longpass Filter; t=5 mm 500nm

The 84-756 is a high-performance longpass filter, measuring 50 mm in diameter and 5 mm in thickness, sourced from Edmund Optics. This filter is designed to transmit light at wavelengths above 500 nm, making it ideal for applications that require the removal of shorter wavelengths.

The filter boasts a circular shape and is constructed from UVFS Mal-1965 material, a common choice for optical components due to its excellent transmission properties and durability. The 84-756 filter features a thin lens shape, which is beneficial in applications where space is a constraint.

The front and back surfaces of the filter are coated with EDM 62-976, a hard coating that enhances the filter's resistance to scratches and other forms of damage, ensuring longevity and reliability in operation. This coating also contributes to the filter's overall optical performance, reducing unwanted reflections and increasing transmission.

The filter's physical data includes a cut-on wavelength of 500 nm, indicating the point at which the filter begins to transmit light. The cut-off wavelength is 0 nm, meaning the filter transmits all wavelengths longer than its cut-on value.

The 84-756 filter is currently in stock and available for purchase through the Edmund Optics website. With its high-performance characteristics and robust construction, this filter is an excellent choice for a wide range of optical applications.
