47-620 25 mm Dia. Traditional Coated OD 2.0 Longpass Filter; t=3mm 700nm

The 47-620 is a Longpass Filter, measuring 25 mm in diameter and 3 mm in thickness, sourced from the reputable vendor, Edmund Optics. This filter is designed to transmit light with wavelengths above 700 nm, while blocking light with shorter wavelengths, making it ideal for applications that require the isolation of specific wavelength ranges.

The filter is constructed from UVFS Mal-1965 material, and features a Thin Lens shape. The front and back surfaces of the filter are coated with EDM 49-030, a coating type known for its durability and performance. This coating enhances the filter's functionality, providing a high level of transmission and blocking capabilities.

The filter's physical data includes a cut-on wavelength of 700 nm, indicating the wavelength at which the filter begins to transmit light. The cut-off wavelength is 0 nm, meaning the filter blocks all wavelengths shorter than 700 nm. This makes the 47-620 particularly suitable for applications that require the blocking of shorter wavelengths, such as infrared spectroscopy or astronomy.

The filter is currently in stock and available for purchase through the Edmund Optics website, as indicated by its weblink status. For more detailed information or to make a purchase, users can follow the provided weblink.
