64-618 12.5 mm Dia. Traditional Coated OD 2.0 Longpass Filter; t=1.5mm 525nm
The 64-618 is a Longpass Filter, a type of optical filter that transmits wavelengths longer than a specified value, while blocking shorter wavelengths. This particular model has a diameter of 12.5 mm and a thickness of 1.5 mm, making it suitable for a wide range of optical applications.
The filter is manufactured by Edmund Optics, a leading supplier of optical components, and is identified by the catalog number 64-618. It is made from UVFS Mal-1965, a material specifically designed for optical applications. The filter's cut-on wavelength is 525 nm, meaning it begins to transmit wavelengths at this point and beyond. The cut-off wavelength is 0 nm, indicating that it blocks all wavelengths shorter than the cut-on value.
The 64-618 features a coating on both the front and back surfaces, identified as EDM 64-618. This coating is designed to enhance the filter's performance and durability. The filter's shape is described as a Thin Lens, further expanding its potential applications in optical systems.
