AO Tunable Filters

electronically tunable bandpass filter (광대역 광원 (크세논, 할로겐 램프)과 함께 들어오는 빛에서 단일 또는 다중 파장을 선택하여 전송할 수 있습니다.

An AOTF is a solid-state, electronically tunable bandpass filter, which uses the acousto-optic interaction inside an anisotropic medium. These filters can be used with multi-lines sources (mixed gas lasers, Laser diodes…) or with broadband light sources (Xenon,Halogen lamps…). They allow to select and transmit a single or multiple wavelengths from the incoming light.

AA proposes a whole range of AOTFs based on TeO2 with shear acoustic mode. The filters are designed so as to get the best performances in each wavelength range and to satisfy most of the applications: resolution down to 1 nm, Field of view up to 20 degrees, apertures up to 10 mm…

In most cases, the filtered output from the tunable filter is made collinear to make easier the use of these devices, and to satisfy fiber pigtailing conditions. A random input polarization will be separated into two orthogonal polarizations (order -1 and +1).
