47-509 25 mm Dia. Hard Coated Laser Line Longpass Filter 980nm
The 47-509 is a Longpass Filter from Edmund Optics, designed with a circular base shape and a diameter of 25 mm. This filter boasts a thickness of 3.5 mm and is constructed from UVFS material with the Mal-1965 material ID. The filter's primary function is to allow light transmission above a specified wavelength while blocking lower wavelengths.
The 47-509 filter is hard coated on both the front and back surfaces with the EDM 47-509 coating. This coating enhances the filter's durability and performance. The filter's cut-on wavelength is 980 nm, indicating that it begins to transmit light at this wavelength and above. The cut-off wavelength is 0 nm, meaning it blocks all wavelengths below 980 nm.
This filter is designed for use with laser line applications and is currently in stock, as indicated by its weblink status.
