49-024 12.5 mm Dia. Traditional Coated OD 2.0 Longpass Filter; t=1.5mm 400nm
The 49-024 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 49-024. It is available for purchase directly from the vendor's website, where it is currently listed as in stock.
The 49-024 features a cut-on wavelength of 400 nm, meaning it begins to transmit light at this point in the spectrum. It does not have a specified cut-off wavelength, indicating that it continues to transmit all longer wavelengths.
The filter's front and back surfaces are coated with the EDM 49-024 coating, which is designed to enhance its optical performance. The filter's shape is described as a Thin Lens, suggesting that it has been designed to focus or collimate light.
