49-037 12.5 mm Dia. Traditional Coated OD 2.0 Longpass Filter; t=1.5mm 1050nm

The 49-037 is a Longpass Filter, a type of optical filter that passes longer wavelengths of light and blocks shorter wavelengths, from the renowned 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 1050nm, 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 specific characteristic makes it an ideal choice for applications where the detection of longer wavelengths is crucial.

The 49-037 features a circular shape and is made of UVFS Mal-1965 material, a common choice for optical filters due to its excellent optical properties. The filter is coated on both the front and back with Edmund Optics' proprietary coatings, denoted as EDM 49-037, further enhancing its performance and durability.

The filter's thin lens shape allows for easy integration into various optical systems. It is currently in stock and available for purchase through the Edmund Optics website, as indicated by its weblink status. For more detailed information, users are encouraged to visit the provided weblink.
