Summary Box:
Ultra and standard series dual-band bandpass filters from Alluxa with superior performance and durability. Available over a broad range of wavelengths and specifications - 25mm diameter.Description:
Alluxa bandpass filters deliver superior performance and durability over traditional laminated filters. All Alluxa optical filters are hard-coated using our innovative SIRRUS™ plasma deposition process. ULTRA Series filters provide better overall performance than our standard fluorescence filters by using a combination of tight wavelength control, ultra-steep edges, deeper blocking, and the industry's highest transmission levels. Through a combination of precision wavelength control, ultra-steep edges, deep blocking, and the industry's highest transmission levels, Alluxa’s ULTRA Series of hard-coated, thin-film optical bandpass filters will optimize the performance of a variety of instruments. ULTRA Series bandpass filters are ideal for use in applications such as fluorescence microscopy, flow cytometry, Raman spectroscopy, LIDAR, and spectral imaging. Single-band, multiband, wideband, ultra-narrow, and narrowband filters are available.
Depending on the wavelength ranges and requirements of your system, ULTRA Series bandpass filters can be custom designed to meet one or more of the following challenging specifications:
• Up to 99% transmission for passbands in the visible range
• Up to OD10 wide range out of band blocking by design
• Edge transitions as steep as 0.5% of CWL from 50% T to OD6
• CWL at any wavelength from the UV to the mid IR (~250 nm to 6.2 µm)
• Tolerances as tight as ± 0.25% of CWL
• TWE as low as 0.01 wave RMS / inch measured at 632.8 nm
The products listed below are all of 25mm diameter part size. If the products below are not suitable for your application, please contact us to discuss a custom solution.
