84-698 12.5 mm Dia. Hard Coated High Performance OD 4.0 Shortpass Filter; t=1.5 mm 625nm
The 84-698 is a high-performance shortpass filter, designed and manufactured by Edmund Optics, a leading global provider of optical components. This filter, with a diameter of 12.5 mm, is specifically engineered for use in applications where the control of wavelengths is crucial.
The filter is characterized by its shortpass properties, with a cut-on wavelength of 0 nm and a cut-off wavelength of 625 nm. This means it allows wavelengths shorter than 625 nm to pass through while blocking longer wavelengths, making it ideal for applications where the removal of infrared light is necessary.
The filter is made from UVFS Mal-1965, a material known for its optical properties and durability. It has a thickness of 1.5 mm, providing robustness and stability in its operation. The filter is coated on both sides with EDM 84-698, a hard coating that enhances its durability and resistance to wear and tear, ensuring a long lifespan.
The filter's geometry is in the form of a thin lens, which is beneficial in applications where space is a constraint. The filter is currently in stock and available for immediate shipping, as indicated by its weblink status.
