Know-how about Optical Notch Filters
Why Noni Notch Filters?
Based on the interference effect of light waves, through precise coating design and optical calculations, notch filters can achieve selective blocking of specific wavelengths or narrow bands while maintaining transmission of other wavelengths. This makes notch filters an important tool for precise spectral selection and signal denoising in optical systems, and plays an important role in laser spectroscopy, microscope imaging, and other life science research.
How Can Notch Filters Work with Other Optical Filters
To achieve a broader range of filtering effects and cater to specific wavelengths and optical characteristics in various applications, the use of notch filters in conjunction with other filters proves highly effective. By combining these filters, you can create more diverse and complex filtering solutions that precisely address the unique requirements of your optical systems.
If you need any help, our expertise in filter design and manufacturing ensures seamless compatibility and exceptional results in practical applications. Here are a few common combinations that a notch filter might be paired with and their effects:
Longpass Filter + Notch Filter: A long pass filter allows transmission of all wavelengths longer than a certain cutoff wavelength, while a notch filter selectively rejects specific wavelengths. Such combinations can be used to create bandpass filters that transmit light in a specific range of wavelengths while blocking other wavelengths.
Short Pass Filter + Notch Filter: A short pass filter allows transmission of all wavelengths shorter than a certain cutoff wavelength, while a notch filter selectively rejects specific wavelengths. Such combinations can be used to create bandpass filters that transmit light in a specific range of wavelengths while blocking other wavelengths.
Linear Polarizing Filter + Notch Filter: A linear polarizing filter selectively passes light polarized in one direction, while a notch filter selectively rejects specific wavelengths. Such a combination enables the selective transmission of optical signals with specific wavelengths and polarization states.
Polarizing Beam Splitter + Notch Filter: A polarizing beam splitter splits incoming polarized light into two different polarization states, while a notch filter selectively rejects specific wavelengths. Such combinations can be used to selectively transmit optical signals of specific wavelengths and polarization states.
Neutral Density Filter + Notch Filter: Neutral density filters reduce the light intensity at all wavelengths evenly, while notch filters selectively reject specific wavelengths. Such a combination can be used to achieve a uniform reduction in light intensity over a specific wavelength range.
Multiple notch filters + Notch Filter: Multiple notch filters can be used together to selectively block optical signals of multiple different wavelength ranges to achieve more complex optical filtering effects
Notch Filter Applications
Optical notch filters find applications in various fields, including spectroscopy, fluorescence microscopy, telecommunications, laser systems, and biomedical imaging, where precise control of specific wavelengths is essential for accurate measurements and signal isolation.
Spectral Analysis: Notch filters can selectively filter out a portion of the spectrum within a spectral range, which is important for accurate analysis and identification of specific components in a sample.
Laser Fluorescence Microscopy: Notch filters can selectively block or transmit specific fluorescent signals, allowing the microscope to more precisely capture structures or molecular markers of interest when imaging cells and tissues.
Optical communication: The unique feature of the notch filter in optical communication systems is that it can selectively transmit or block optical signals of specific wavelengths, which is essential for realizing multi-wavelength communication or wavelength division multiplexing technology.
Solar applications: In solar cells and solar collectors, notch filters can selectively transmit specific wavelengths of sunlight to improve energy conversion efficiency.
FAQ, Frequently Asked Questions
Some important information you might want to know.
Do you offer standard optic components (Shelf Products) ?No, we don’t sell shelf products. We offer customization service according to your requirements for specific projects or brands equivalent.
What substrates do you use for custom optical components?Our most frequently used substrates are Zinc Selenide (ZnSe), Zinc Sulfide (ZnS), Silicon, Germanium (Ge), Copper, Aluminum, Mo, PMMA, Chalcogenide Glasses, etc.
Can you help to customize according to samples we offered?We highly recommend producing according to specific drawings. Since there are lots of indexes which can not be obtained by measuring samples, such as requirements of material.
What's your MOQ for customized projects?We set very low MOQ for customization projects. But of course, price will be quoted according to the quantity to cover our production cost.
How to protect my personal information and our technical information?Don’t worry, we will sign the NDA with all our customers if needed.
What shipping methods are available?We commonly use UPS, FedEx, DHL, TNT, SF, EMS etc. We also accept your own appointed forwarder.
What's the lead time for sampling, for mass production?For customization projects, sampling lead time will be 1 to 2 weeks. For mass production, 1 to 2 months for orders with quantity 1000 to 2000 pieces.
Can you offer all the Certificates required by our customs and our company?Every product that leaves the factory has been carefully tested. We would like to offer you all the certificates required by your side. Such as:
All products delivered by us will be carefully cleaned and packaged.
Raw material certificate and technical drawing
RoHS Report of substrate
Inspection report (data) of 3D optical profiler, surface flatness etc.
