49-025 12.5 mm Dia. Traditional Coated OD 2.0 Longpass Filter; t=1.5mm 450nm
The 49-025 is a Longpass Filter, a type of optical element designed to transmit light with wavelengths longer than a specified value while blocking shorter wavelengths. In this case, the cut-on wavelength is 450nm, meaning it allows transmission of light with wavelengths longer than 450nm.
This filter, sourced from Edmund Optics, has a diameter of 12.5mm and a thickness of 1.5mm, making it suitable for various optical applications. The base shape is circular, and it features a Thin Lens shape, which is beneficial in maintaining the optical path length and reducing aberrations.
The filter is made from UVFS Mal-1965 material, a common choice for optical filters due to its excellent optical properties. It is coated on both the front and back surfaces with EDM 49-025, a proprietary coating that enhances its performance and durability.
The catalog number for this item is 49-025, and it is currently in stock, according to the vendor's website. For more information or to make a purchase, users can visit the provided weblink.
