The 39-337 is a Bandpass Filter with a 12.5 mm diameter and a thickness of 3.5 mm, specifically designed for a central wavelength of 1064 nm. This filter is sourced from Edmund Optics, a renowned vendor in the optical industry. The filter is hard coated on both the front and back surfaces, ensuring durability and longevity.
The Bandpass Filter is a type of optical filter that allows light to pass within a certain range of wavelengths, while blocking other wavelengths. In this case, the 39-337 filter is designed to allow light with a wavelength of 1064 nm to pass through, while blocking light of other wavelengths. The filter's cut-on wavelength is 1061.5 nm, and the cut-off wavelength is 1066.5 nm, indicating a narrow bandwidth of 5 nm.
The filter is shaped as a Thin Lens, which is a lens with a very small focal length compared to its diameter. This shape allows the filter to be used in various optical systems without significantly altering the path of light.
