84-726 50 mm Dia. Hard Coated High Performance OD 4.0 Shortpass Filter; t=5 mm 675nm

The 84-726 is a high-performance shortpass filter, designed and manufactured by Edmund Optics, a leading global supplier of optical components. This filter, with a catalog number 84-726, is specifically engineered for use in applications where the transmission of light below a specified wavelength is required. The filter boasts a 50 mm diameter and a thickness of 5 mm, making it suitable for a wide range of optical systems.

The 84-726 filter is a shortpass filter, a type of optical filter that transmits short wavelengths and reflects or absorbs longer wavelengths. In this case, the cut-on wavelength is 0 nm, and the cut-off wavelength is 675 nm. This means that the filter will allow light with wavelengths up to 675 nm to pass through while blocking or attenuating light with wavelengths greater than 675 nm. The cut-off wavelength is a critical parameter in the selection of a shortpass filter, as it determines the wavelength at which the filter starts to block light.

The filter is made from UVFS Mal-1965, a material known for its excellent optical properties. The front and back surfaces of the filter are coated with EDM 84-700, a hard coating that enhances the filter's durability and resistance to environmental factors such as humidity, temperature changes, and mechanical stress.

The 84-726 filter has a thin lens shape, which contributes to its compact design and ease of integration into optical systems. The filter is currently in stock and available for immediate shipping, as indicated by its weblink status.
