A 1064nm bandpass filter is a type of optical filter that selectively allows light with a specific wavelength of 1064nm to pass through while blocking other wavelengths of light. This filter is commonly used in applications that require laser light filtering and isolation, as the 1064nm wavelength is frequently used in laser applications, including laser cutting, welding, marking, and engraving.
