84-669 12.5 mm Dia. Traditional Coated OD 2.0 Longpass Filter; t=1.5mm 1450nm

The 84-669 is a Longpass Filter, part of the extensive catalog of optical elements offered by Edmund Optics. This particular filter boasts a 12.5 mm diameter and a thickness of 1.5mm, making it suitable for a wide range of optical applications.

The Longpass Filter is designed to transmit wavelengths above a specified cut-on value while blocking wavelengths below this point. In the case of the 84-669, the cut-on wavelength is 1450nm, making it ideal for applications where longer wavelengths need to be isolated or emphasized.

The filter is made from UVFS Mal-1965, a material known for its optical properties. The front and back of the filter are coated with EDm 84-669, a coating that enhances the filter's performance and durability.

The filter's geometry is defined by its circular shape and thin lens design, which contributes to its versatility and ease of integration into various optical systems. The 84-669 is currently in stock and available for purchase through the Edmund Optics website, as indicated by its valid weblink status.
