3rd Millennium Filters
Millennium Filters fill the market position of high-performance
commodity filters for widespread research and instrumentation
applications. They are available as stock bandpass, longpass, and
shortpass assemblies. They are also available as fluorescence
microscopy filter sets for the most commonly used fluorophores. For
all products delivery times are short, pricing is competitive with
industry standard catalog filters, and performance is high.
made using this technology offer the advantages of surface coatings,
along with the benefits of extreme phase thickness coatings. At the
heart of each filter is the patented, hermetically-sealed, physical
assembly which protects the dielectric coatings and eliminates the
potential environmental instability of surface coatings. The assembly
does not use polymer adhesives, minimizing thermal instability and
potential photon damage. The patented assembly results in longer
filter life, increased transmission, reduced parasitic fluorescence
and significantly reduced Transmitted Wavefront Distortion (TWD).
Millennium stock filters utilize proprietary ALPHA technology,
producing edge slopes which are 10 times steeper than industry
standard Fabry Perot designs. As a result, passbands can be made
wider while still achieving the blocking requirements of narrower,
less steep designs. In other words, wider 3RD Millennium filters
outperform narrower standard designs by providing not only improved
transmission, but better blocking and higher signal-to-noise.
critical feature of filter design is the transition from blocking to
transmission. Precise location of band edges, coupled with steep
slopes, allows for optimal transmission of spectral energy. While
industry standard filters are defined by Center Wavelength (CWL) and
Bandwidth (FWHM), 3RD Millennium filters are specified by the
critical cut-on and cut-off edges, resulting in much more accurate
band placement and bandwidth. The 3RD Millennium manufacturing line
incorporates CNC, robotics, and refined process allowing a high
degree of consistency.
Millennium technology is protected by patent #6,918,673.
