64-684 25 mm Dia. Traditional Coated OD 2.0 Longpass Filter; t=3mm 875nm
The 64-684 is a Longpass Filter, part of the extensive catalog of optical elements provided by Edmund Optics. This filter has a circular base shape and is made of UVFS Mal-1965 material. It boasts a diameter of 25 mm and a thickness of 3 mm, making it a suitable choice for various applications.
The filter's primary function is to allow light of longer wavelengths to pass through while blocking shorter wavelengths. The cut-on wavelength is 875 nm, indicating that it begins to transmit light at this point on the spectrum. The cut-off wavelength is 0 nm, meaning it blocks all wavelengths shorter than 875 nm.
The 64-684 filter features a Thin Lens shape and is coated with EDM 64-677 on both the front and back. This coating enhances the filter's performance and durability. The filter's current status is in stock, and it is available for purchase through the provided weblink.
