Summary Box:
ULTRA Series multi-edge longpass dichroic filters with cut-on wavelengths available from 402m to 763nm.Description:
ULTRA Series polychroic filters have a comb-like design with multiple transmission bands separated by multiple reflection bands. In fluorescence applications, this allows the emission light from several different fluorophores to be simultaneously directed to the detector, while the excitation light is directed to the sample.
Depending on the wavelength ranges and requirements of your system, ULTRA Series dichroic or polychroic filters can be custom designed to meet one or more of the following challenging specifications:
- Up to 99% transmission
- Up to 99.5% reflection
- Edge wavelengths from the UV to the mid IR (~250 nm to 6.2 µm)
- Tolerances as tight as ± 0.5% of edge wavelength
- Edge transitions as steep as 1% of edge wavelength from 10% T to 90% T
- TWE as low as 0.01 wave RMS / inch measured at 632.8 nm
