33-971 12.5 mm Dia. Traditional Coated Infrared (IR) Longpass Filter; t=1mm 4500nm
The 33-971 is a Longpass Filter with a 12.5 mm diameter and a thickness of 1mm, sourced from the renowned optical components vendor, Edmund Optics. This filter is designed to transmit infrared (IR) radiation with wavelengths longer than 588nm, while blocking shorter wavelengths.
The filter is made from Germanium Burnett, a material known for its excellent optical properties in the infrared spectrum. It features a cut-on wavelength of 4500nm, meaning it begins to transmit light at this wavelength and beyond. The cut-off wavelength is 0nm, indicating that it blocks all wavelengths shorter than 588nm.
The 33-971 filter is coated on both the front and back surfaces with the EDM 33-971 coating. This coating enhances the filter's performance and durability, ensuring reliable and consistent operation. The filter's shape is that of a Thin Lens, which is often used in optical systems to focus or disperse light.
This filter is currently in stock and can be purchased directly from the Edmund Optics website using the provided weblink. With its high-quality construction, precise specifications, and reliable performance, the 33-971 is an excellent choice for a wide range of optical applications.
