64-630 25 mm Dia. Traditional Coated OD 2.0 Longpass Filter; t=3mm 725nm

The 64-630 is a Longpass Filter, part of the extensive catalog of optical elements offered by Edmund Optics. This filter, with a 25 mm diameter and a thickness of 3 mm, is designed for use in applications where specific wavelengths need to be isolated or blocked.

The Longpass Filter features a cut-on wavelength of 725 nm, meaning it begins to transmit wavelengths at this point and continues to do so for longer wavelengths. The cut-off wavelength, on the other hand, is 0 nm, indicating that it does not block shorter wavelengths. This filter is made of UVFS Mal-1965 material and has a circular shape, making it suitable for a wide range of optical applications.

The 64-630 filter is coated on both the front and back with EDM 64-622, a type of coating that enhances its performance and durability. The filter's shape is described as Thin Lens, further expanding its potential uses in various optical systems.
