3 rd Millennium Filters Steep slopes Specified by the critical cut-on/cut-off edges Standard 25 mm diameter off the shelf components 3 RD Millennium filters are manufactured using Omega Optical’s proprietary ALPHA coating technology, a process which produces exceptionally steep cuton and cut-off slopes. The result is precise location of cut-on and cut-off edges, the ability to place transmission and rejection regions extremely close together, and higher attenuation between the passband and the rejection band. These filters are produced in custom engineered coating equipment that progresses from raw material to complete assemblies in a shortened manufacturing cycle. The coating chamber is load-locked so that it remains under stable high vacuum conditions between coating cycles. Control and design of manufacturing processes lead to yield and product uniformity Short manufacturing cycles results in controlled inventories and shorter lead times Specifying by the critical cut-on and cut-off edges will result in much more accurate band placement and bandwidth. Bandpass filters are made using a combination of an ALPHA longpass (cut-on) and ALPHA shortpass (cut-off). Longpass and shortpass filters are each made using a single surface coating. Passbands can be made wider and still achieve the blocking requirements of narrower, less steep designs. Wider bandpass filters outperform narrower standard designs with improved transmission, deeper blocking, and improved signal-to-noise. 3 rd Millennium part numbers are unassigned. To order a 3 rd Millennium filter: Longpass – specify a cut-on wavelength Shortpass – specify a cut-off wavelength Bandpass – specify a cut-on & cut-off wavelength Example: Product SKU 3RD650LP Example: Product SKU 3RD520SP Example: Product SKU 3RD580-600 100 Actual Transmission 16 Typical Optical Density Transmission (%) 14 80 3 RD Millennium Bandpass 12 3 RD Millennium Bandpass 60 10 Standard 8 Fabry Perot 40 Bandpass 6 4 20 2 0 500 520 540 560 580 600 Wavelength (nm) Optical Density Standard Fabry Perot Bandpass 0 425 475 525 575 625 675 Wavelength (nm) 62 For current product listings, specifications, and pricing: www.omegafilters.com • sales@omegafilters.com 1.866.488.1064 (toll free within USA only) • +1.802.254.2690 (outside USA)
Steep slopes Specified by the critical cut-on/cut-off edges Standard 25 mm diameter off the shelf components 3 rd Millennium Filters 3 rd Millennium Filters 3 rd Millennium filters are offered every 10 nm from 400-700 nm, every 20 nm from 700-800 nm and every 50 nm from 800 nm to 1100 nm. Filter Type Wavelength Range Transmission Attenuation Range Attenuation Longpass Cut-On from 400-700 nm ≥ 90% peak UV to cut-on oD 6 at every 10 nm Cut-On from 700-800 nm at every 20nm Cut-On from 800-1100 nm at every 50 nm Shortpass Cut-Off from 400-700 nm ≥ 90% peak Cut-off to 1.3x cut-off OD 6 at every 10 nm Cut-Off from 700-800 nm at every 20 nm Cut-Off from 800-1100 nm at every 50 nm Bandpass Cut-On + Cut-Off from ≥ 80% peak UV to 1.3x cut-off oD 6 400-700 nm at every 10 nm 700-800 nm at every 20 nm 800-1100 nm at every 50 nm Attenuation Extension: When using a silicon detector, in some cases a blocker filter is required to extend the attenuation range to 1100 nm nominally. For optimal performance we recommend locating a separate blocking filter in a position remote from the 3 rd Millennium filter. Please see page 94 for IR Blocking Filters.
