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.
SUPPLIER: ALLUXA, INC.
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 13 µm)
◆ Tolerances as tight as ± 0.25% of CWL
◆ TWE as low as 0.01 wave RMS / inch measured at 632.8 nm
ULTRA Series multiband filters can be designed with over 10 transmission bands, greater than OD8 blocking between bands, steep edges, and up to 98% transmission. They are perfect for use as excitation or emission filters in fluorescence techniques that require the simultaneous detection of multiple fluorophores in a single sample.
