A band pass filter is a device that passes frequencies within a certain range and rejects (attenuates) frequencies outside that range. Optical band pass filters are used to selectively transmit a portion of the spectrum while rejecting all other wavelengths. Optical band pass filters are ideal for a variety of applications, such as fluorescence microscopy, spectroscopy, clinical chemistry, wireless transmitters, receivers or imaging. These filters are typically used in the life science, industrial, or R&D industries.
XF Photonics offers a wide variety of optical band pass filters.
XF Photonics Co.,Ltd can supply all kinds of bandpass filter, which are made by BK7 Glass, Fused silica or sapphire, Si, Ge, ZnS, ZnSe crystal. The available center wavelengths are 400,420,425,430, 470, 530, 532,550,570,610,635,650, 670,780,808,950,970,1340nm etc.
