84-671 12.5 mm Dia. Traditional Coated OD 2.0 Longpass Filter; t=1.5mm 1550nm

The 84-671 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 1550nm, meaning it begins to transmit light at this wavelength, while blocking all wavelengths shorter than this. This characteristic makes it ideal for applications where the detection of longer wavelengths is crucial, such as infrared (IR) spectroscopy, night vision, and heat-seeking devices.

The 84-671 model features a Thin Lens shape, which is a lens with a very short focal length compared to its diameter. This shape allows for a compact and efficient design, making it a popular choice for many optical systems.

The filter is coated on both the front and back with the EDM 84-671 coating, enhancing its performance and durability. This coating ensures the filter maintains its specified characteristics even under harsh conditions, making it a reliable choice for demanding applications.
