A band pass filter is a device that passes frequencies within a certain range and rejects (attenuates) frequencies outside that range, and it’s used to selectively transmit a portion of the spectrum while rejecting all other wavelengths.

1、What are bandpass filters?
A bandpass filter is a device that passes frequencies within a certain range and rejects (attenuates) frequencies outside that range, and it’s used to selectively transmit a portion of the spectrum while rejecting all other wavelengths.
2、In what fields can Bandpass Filters be widely used?
Optical band pass filters are typically used in for the life science, industrial, or R&D industries, and also are ideal for a variety of applications, such as fluorescence microscopy, spectroscopy, clinical chemistry, wireless transmitters, receivers or imaging.
3、What UNI Optics can supply for you?
UNI OPTICS can supply all kinds of bandpass filters, which are made by BK7 Glass, Fused silica, B270, Color Glass, etc. The custom specifications are available upon request.

Longpass Filters for Vision inspection Apllication
Longpass filters are ideal for a variety of applications, such as gas monitoring, temperature, sensing, thermal imaging and motion sensing, etc. Longpass filters block shorter wavelengths and transmit longer wavelengths. Blocking can be from reflectance, absorption or a combination. Transmission in the pass band can be enhanced with an antireflection coating on the second surface.
Optical glass neutral density filters
A Neutral Density filter allows a photographer to control the exposure in an image very easily. The filter stops light reaching the camera sensor, therefore allowing us to leave the camera with a higher aperture for a longer amount of time.
