ULTRA Series Notch Filters (by Alluxa)
The deep blocking, tight wavelength control, steep edges, and wide-range transmission of ULTRA Series thin-film notch filters all allow for precision blocking of lasers or other light sources, without sacrificing the quality of target signals.
Each hard-coated ULTRA Series optical notch filter is designed and rigorously tested to exceed the the most advanced system requirements. They are all ideal for use in applications such as fluorescence microscopy, endoscopy, and DNA sequencing.
ULTRA Series notch filters can also be custom designed with extremely steep edges for use in Raman spectroscopy applications. In some Raman applications, notch filters are used to block the excitation laser wavelength while simultaneously transmitting both Stokes and anti-Stokes signals to the detector. If the notch edges are not steep enough, then the signals close to the laser wavelength will be lost.
Depending on the wavelength ranges and requirements of your system, ULTRA Series notch filters can be custom designed to meet one or more of the following challenging specifications:
- Up to OD8 precision blocking by design
- Up to 99% transmission
- Notch CWL at any wavelength from the UV to the mid IR (~250 nm to 6.2 µm)
- Tolerances as tight as 0.25% of notch CWL
- TWE as low as 0.01 wave RMS / inch measured at 632.8 nm
Multi-notch filter with steep edges, deep blocking, and wide range transmission that is close to 100%.
ULTRA Series multi-notch filters can be designed with greater than OD8 blocking between bands, steep edges, and up to 98% transmission. They are perfect for applications that require simultaneous blocking of multiple laser lines.
Quality and consistency from an innovative thin-film coating process
Alluxa thin-film optical interference filters and dielectric mirrors are all hard-coated using our SIRRUS™ plasma deposition process on equipment that was designed and built by our team. This allows us to reliably and repeatedly produce the same high-performance thin-film notch filters over several different coating runs, which translates to consistent performance across all of your systems.
