33-972 12.5 mm Dia. Traditional Coated Infrared (IR) Longpass Filter; t=1mm 7300nm

The 33-972 is a Longpass Filter, a type of optical filter that transmits wavelengths longer than a specified value, while blocking shorter wavelengths. This particular model, sourced from Edmund Optics, has a diameter of 12.5 mm and a thickness of 1 mm, making it suitable for a wide range of optical applications.

The filter is made from Germanium Burnett, a material known for its excellent infrared transmission properties. It is designed to cut on at 7300 nm, meaning it begins to transmit light at this wavelength, and has a cut off of 0 nm, indicating it blocks all wavelengths shorter than this. This makes it ideal for applications that require the detection or manipulation of infrared light.

The 33-972 features a Thin Lens shape, which is designed to minimize optical aberrations and distortions. It is coated on both the front and back with the EDm 33-972 coating, which enhances its performance and durability.
