Multiband pass filters are designed to transmit multiple specific wavelength bands or spectral regions simultaneously while blocking unwanted wavelengths. They find important applications in biomedical imaging
Band pass filter extracts specified wavelength from any wavelength range.
By designating pass (or transmission) band width and wavelength range to be blocked (or rejected), various spectral characteristics can be obtained.
An edge filter, also known as a cut-on/cut-off filter or long pass short pass filter, is designed to transmit or block light within a specific wavelength range.
What are Channel Skip Filters
In optical communications, there is a demand for high-capacity transmission systems. This has led to the creation of sophisticated technologies, like Wavelength Division Multiplexing (WDM).
Longchuang Optronics Company was in exhibiting the CIOE 2023,
Took place at Shenzhen World Exhibition & Convention, China from September 6-8, 2023 and achieved complete success.
Field of view, or FOV, is the angular range over which a collimated or uncollimated beam is incident on the filter’s first surface, measured relative to the surface normal at the surface that the beam is incident upon.
