84-667 12.5 mm Dia. Traditional Coated OD 2.0 Longpass Filter; t=1.5mm 1350nm

The 84-667 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 1350nm, meaning it starts to transmit light at this wavelength, and has no specified cut off wavelength, indicating it continues to transmit longer wavelengths. This makes it ideal for applications where the detection of longer wavelengths is crucial.

The 84-667 features a traditional coating on both the front and back surfaces, denoted as 'edm 84-667'. This coating enhances the filter's performance and durability, ensuring reliable and consistent optical performance.

The filter's geometry is shaped as a Thin Lens, a type of lens with a short focal length and a small diameter relative to its focal length. This shape allows for more compact and efficient optical systems.
