Standard Longpass Filter/Optical Longpass Filter/Longpass Optical Fiters

Product Description

General Introduction: The Raytek long pass edge filter is made of hard dielectric filter coating, which can produce a very steep transition between the pass band and the stop band, and the performance is far better than that of the absorption colored glass filter.
Long pass filters are used to pass through light longer than the cut-off wavelength and shield light shorter than the cut-off wavelength by absorbing or reflecting. Long pass filter has many applications. It can be combined with short-pass filter to realize the function of adjustable band-pass filter
