64-634 50 mm Dia. Traditional Coated OD 2.0 Longpass Filter; t=5mm 525nm
The 64-634 is a 50 mm diameter Longpass Filter, manufactured by Edmund Optics, with a thickness of 5mm. This filter is designed to transmit light with wavelengths above 588 nm, while blocking shorter wavelengths. The cut-on wavelength is 525 nm, indicating that it starts to transmit at this wavelength.
This filter is made from UVFS Mal-1965 material, a common choice for optical applications due to its durability and optical properties. The filter features a Thin Lens shape, which is beneficial for applications where space is a constraint.
The front and back surfaces of the filter are coated with EDM 64-618, a proprietary coating developed by Edmund Optics. This coating enhances the filter's performance by reducing surface reflections and improving transmission.
The filter is available for purchase through the Edmund Optics website, and as of the time of data collection, it is in stock. For more detailed information, including technical specifications and purchasing options, please refer to the provided weblink.
