Know-how about Shortpass Filters
Why Noni Shortpass Filters?
The purpose of a short-pass filter is to selectively pass wavelengths shorter than the filter cutoff wavelength while blocking regions of shorter wavelengths (higher energy) than the blocking band.Short-pass filters are widely used in life sciences and can provide highly selective and precise wavelength transmission, providing important optical support for fluorescence microscopy and other biological imaging and analysis techniques. We offer both Shortpass filters designed for a 0° angle of incidence,and shortpass dichroic filters for a 45° angle of incidence.
What is the Difference between Longpass and Shortpass Filters?
Shortpass filters and longpass filters are two different types of optical filters, which have the following differences:
Shortpass filters transmit short-wavelength light and block long-wavelength light; long-pass filters transmit long-wavelength light and block short-wavelength light. Their cut-off wavelengths are opposite, the short-pass filter has a longer cut-off wavelength, and the long-pass filter has a shorter cut-off wavelength.
The short-pass filter and the long-pass filter complement each other in the selection of the spectral range, and they can be combined to form a band-pass filter, which can transmit optical signals in a specific wavelength range and block other wavelengths.
These two filters are widely used in the field of optics to realize the selective transmission, separation, and enhancement of optical signals to meet the needs of different applications.
How Can Shortpass Filters Work with Other Optical Filters
Short pass filters can be combined with other filters to achieve different effects and meet specific optical needs. Here are a few common filters that short pass filters may be paired with and their effects:
Longpass Filters + Shortpass Filters: When these two filters are connected in series, their stop bands and pass bands overlap to form a specific wavelength range, which is a bandpass filter. A bandpass filter is an optical filter that selectively transmits a specific range of wavelengths while blocking other wavelengths. By adjusting the parameters and characteristics of the shortpass filter and longpass filter, different band-pass filters can be customized to meet the needs of specific wavelength ranges in different applications.
Linear Polarizing Filters + Shortpass Filters: Linear polarizing filters can pass light polarized in one direction, while shortpass filters selectively reject specific wavelengths. Such a combination enables selective transmission of optical signals with specific wavelengths and polarization states.
Notch Filters + Shortpass Filters: Notch filters selectively reject a portion of the spectrum while transmitting all other wavelengths. Short pass filters can be used in conjunction with notch filters to achieve more complex filtering effects, selectively blocking some wavelengths while transmitting optical signals in other wavelength ranges.
Neutral Density Filters + Shortpass Filters: Neutral density filters reduce light intensity at all wavelengths evenly, while short pass filters selectively reject specific wavelengths. Such a combination can be used to achieve a uniform reduction in light intensity over a specific wavelength range.
Shortpass Filters Applications
Short pass filters have a wide variety of applications in optical applications. Its main function is to selectively transmit light shorter than a certain cut-off wavelength, while blocking longer wavelength light. Here are some common applications for short pass filters:
Spectral analysis: Short-pass filters are widely used in spectroscopy to selectively transmit light in a specific wavelength range to achieve spectral analysis and detection.
Star observation: In the field of astronomy, short-pass filters can be used to selectively transmit light of specific wavelengths from celestial objects to observe and study specific galaxies, star clusters or stars.
Biomedical imaging: In the field of medical imaging, short-pass filters are often used to selectively transmit light of specific wavelengths to achieve different types of biomedical imaging, such as endoscopy and skin imaging.
UV Disinfection: Short pass filters are used in UV disinfection equipment to selectively transmit UV radiation for disinfection and sterilization.
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.
