64-697 50 mm Dia. Traditional Coated OD 2.0 Longpass Filter; t=5mm 400nm

The 64-697 is a Longpass Filter, sourced from Edmund Optics, with a diameter of 50 mm and a thickness of 5 mm. This filter is designed for use in optical systems that require the transmission of longer wavelengths while blocking shorter wavelengths. The cut-on wavelength for this filter is 400 nm, meaning it begins to transmit light at this wavelength and beyond.

The filter is made from UVFS Mal-1965 material, a common choice for optical filters due to its excellent optical properties. It features a Thin Lens shape, which is beneficial in applications where space is limited or a flat surface is required. The filter is coated on both the front and back surfaces with EDM 49-024, a coating that enhances its performance and durability.

This filter is currently in stock and available for purchase through the Edmund Optics website. It is part of a comprehensive catalog of optical elements offered by 3DOptix, designed to meet the diverse needs of our users. Whether you're building a new optical system or upgrading an existing one, the 64-697 Longpass Filter could be a valuable addition to your setup.
