3rd Millennium Filters
3rd 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. For all products delivery times are short, pricing is competitive with industry standard catalogue filters, and performance is high.
3rd Millennium filters allow the user to specify the cut-on and cut-off wavelength of the filter, a Pick n Mix system. The superior spectral performance and longer filter life of these filters make them ideal for use in optical instruments.
The new technology design of the 3rd Millennium filters results in filters with exceptionally steep cut-on and cut-off slopes. This results in more precise location of cut-on and cut-off points, the ability to place transmission and rejection regions extremely close together, and higher attenuation between the pass band and the rejection band.
All this results in a brighter sharper image with a blacker background, while having the ability to tune the filter cut-on and cut-offs to your requirements.
3rd Millennium filters are available as:
-
Longpass Filters which transmit only above a certain "cut-on" wavelength and continue to transmit a wide energy band, click here to view the 3rd Millennium Longpass Filter product range. To learn more about technical information on Longpass Filters, click here.
- Shortpass Filters which transmit only below a certain "cut-off" wavelength and block a wide energy band above this wavelength, click here to view the 3rd Millennium Shortpass Filter product range. To learn more about technical information on Shortpass Filters, click here.
- Bandpass Filters which transmit light only within a defined spectral band ranging from less than one to many nanometers wide, click here to view the 3rd Millennium Bandpass Filters product range. To learn more about technical information on Bandpass Filters, click here.
