48-561 25 mm Dia. Traditional Coated OD 2.0 Longpass Filter; t=3mm 900nm
The 48-561 is a Longpass Filter, part of the extensive catalog of optical elements provided by Edmund Optics. This particular filter boasts a 25 mm diameter and a thickness of 3mm, making it suitable for a wide range of applications. The filter's primary function is to transmit wavelengths above a specified value while blocking those below it. In this case, the cut-on wavelength is 900nm, meaning it allows the transmission of wavelengths greater than or equal to 900nm.
The filter is made from UVFS Mal-1965, a material specifically chosen for its optical properties. It features a Thin Lens shape, which is designed to minimize optical aberrations and distortions. The front and back of the filter are coated with EDm 49-034, a coating that enhances the filter's performance and durability.
The 48-561 is currently in stock and available for purchase through the Edmund Optics website. For more detailed information, including technical specifications and performance data, please refer to the provided weblink.
