84-703 25 mm Dia. Hard Coated High Performance OD 4.0 Shortpass Filter; t=3 mm 425nm
The 84-703 is a high-performance Shortpass Filter, sourced from the renowned optical components vendor, Edmund Optics. This filter boasts a 25 mm diameter and a thickness of 3 mm, making it a versatile choice for various 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 84-703 has a cut-off wavelength of 425nm, meaning it passes wavelengths shorter than 425nm and blocks those longer than this value. This feature makes it particularly useful in applications where the differentiation between shorter and longer wavelengths is crucial.
The filter is made from UVFS Mal-1965 material, a choice that enhances its performance and durability. The front and back of the filter are coated with EDM 84-690, a coating that further improves its functionality and lifespan.
The 84-703 filter is available in a Thin Lens shape, which is beneficial in applications where space is a constraint. The filter's catalog number is 84-703, and it can be found on the Edmund Optics website, where it is currently in stock.
