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.
