33-969 12.5 mm Dia. Traditional Coated Infrared (IR) Longpass Filter; t=1mm 2400nm

The 33-969 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 mm, making it suitable for various optical applications.

The filter is made from Germanium Burnett, a material known for its excellent optical properties, particularly in the infrared (IR) spectrum. It is designed to cut on at 2400 nm, meaning it begins to transmit light at this wavelength, and has no specified cut-off wavelength, indicating it transmits all longer wavelengths.

The 33-969 is coated on both the front and back surfaces with the EDM 33-969 coating. This coating enhances the filter's performance and durability, ensuring reliable operation in its intended application.

The filter's shape is defined as a Thin Lens, suggesting it may have lens-like properties or be used in conjunction with lenses in an optical system. The vendor for this item is Edmund Optics, a reputable supplier of optical components.
