64-698 50 mm Dia. Traditional Coated OD 2.0 Longpass Filter; t=5mm 450nm
The 64-698 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 where the primary requirement is to block shorter wavelengths and transmit longer wavelengths. The cut-on wavelength for this filter is 450 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 transmission characteristics and durability. The filter is coated on both sides with EDM 49-025 coating, which enhances its performance by reducing surface reflections and improving transmission.
This filter is designed for use in Thin Lens optical systems, making it suitable for a wide range of applications. The filter is currently in stock and available for immediate purchase, as indicated by its weblink status.
