Omnidirectional Narrow-Band-Pass, Band-Pass, and Band-Blocking IR Filters

  • Vladimir Kochergin


Narrow-band pass, band-pass and band-blocking optical fi lters are probably Narro p , p most frequently used optical devices. Application areas include among the q Y optical communications, imaging, spectroscopy, lithography, astronomy, and almost any other technology dealing with light. Currently available filters are alm y based on interference in multilayer stacks and have to be used with wellcollimatedted beams and carefully aligned angles of incidence (see section 3.6.2 of this book Despite adding complexity to optical setup (collimation optics book). Desp and mechanical alignment), the need for such filters is so strong that they find many applicationslications even with the required additional penalties.
