Narrowband Filter
Narrowband filters are a subset of bandpass filters with the same basic definition: transmitting optical signals within a specified band while blocking wavelengths on both sides. Their passband is relatively narrow, generally less than 5% of the center wavelength. Their main function is to transmit selected wavelengths and reflect or attenuate others. The half-width is generally controlled to 20 nm or less. Wavelength ranges include ultraviolet, visible, near-infrared, near-infrared again in the source, and far-infrared. The company's narrowband filters use multilayer hard coatings formed by high-vacuum evaporation of nanomaterials with ion-assisted deposition, giving dense coatings and high imaging clarity.

Machine-vision bandpass filter
Optical Filters
Uni-lens
Coating: Antireflection coating Surface Quality: 40/20 Guaranteed peak transmission: >90%
A bandpass filter passes frequencies within a specified range and rejects or attenuates frequencies outside it, selectively transmitting part of the spectrum while rejecting all other wavelengths.

Longpass filter
Optical Filters
Uni-lens
Filter Type [LP Series]: Optical interference or colored-glass filter
Long-pass filters serve gas monitoring, temperature sensing, other sensing, thermal imaging, and motion detection. They block shorter wavelengths and transmit longer wavelengths. Blocking can result from reflection, absorption, or both. An antireflection coating on the second surface can improve passband transmission.
