84-728 50 mm Dia. Hard Coated High Performance OD 4.0 Shortpass Filter; t=5 mm 750nm

The 84-728 is a high-performance Shortpass Filter, sourced from the reputable vendor Edmund Optics. This filter boasts a 50 mm diameter and a thickness of 5 mm, making it a robust and reliable component for various optical applications. The Shortpass Filter type implies that it allows wavelengths shorter than a specified value to pass through while blocking longer wavelengths.

In this case, the cut-on wavelength is 0 nm, and the cut-off wavelength is 750 nm, meaning it permits wavelengths shorter than 750 nm to pass while effectively blocking those longer. This characteristic makes it particularly useful in applications where the differentiation of shorter wavelengths is crucial.

The filter is made from UVFS Mal-1965 material, a detail that may be significant for users who require specific material properties in their optical components. The front and back of the filter are coated with EDM 64-324, a coating that likely contributes to the filter's high performance.

The filter's geometry, with its circular shape and thin lens design, adds to its versatility and ease of integration into various optical systems. The catalog number, 84-728, and the vendor information provided can aid users in sourcing this component or finding similar ones in the extensive Edmund Optics catalog.
