84-670 12.5 mm Dia. Traditional Coated OD 2.0 Longpass Filter; t=1.5mm 1500nm

The 84-670 is a Longpass Filter, a type of optical filter that passes longer wavelengths of light and blocks shorter wavelengths, from the renowned optical components vendor, Edmund Optics. This particular model boasts a 12.5 mm diameter and a thickness of 1.5mm, making it suitable for a wide range of optical applications.

The filter is designed to cut on at 1500nm, meaning it starts to transmit light at this wavelength, and has a cut off of 0, indicating it blocks all wavelengths shorter than its cut on point. This makes it an ideal choice for applications where the detection of longer wavelengths is crucial.

The 84-670 features a circular shape, a common form factor for optical components due to its ease of integration into various systems. It is made from UVFS Mal-1965, a material known for its optical properties, further enhancing the filter's performance.

The filter's front and back are coated with EDm 84-670, a proprietary coating from Edmund Optics that enhances the filter's performance and durability. The filter's shape is described as Thin Lens, suggesting it may have lens-like properties or be used in conjunction with lenses in an optical system.
