AOTF920-xx
NIR AO Tuneable Filter
- SOLID STATE - FAST ACCESS TIME
The AOTF range of acousto-optic devices are solid state optical filters. The wavelength of the diffracted light is selected according to the frequency of the RF drive signal. Isomet-grown tellurium dioxide (Te02), which has been oriented for off-axis mode operation, is utilised as the interaction material. Fast access times and fine spectral bandwidths make these filters ideal for selecting discrete lines from a multi-line laser sources.
The best diffraction efficiency is obtained with linearly polarised input light.
Suitable electronics include the iSPA-SF1 series of frequency synthesizer RF driver/amplifiers
Note:
The drive frequency for any given AOTF is limited to a maximum RF tuning range of one octave (2:1) within the overall range shown in the tables overleaf.
This is illustrates by the three examples, ‘A’,’B’,’C’ highlighted by the coloured bands.
Please specify the desired wavelength range at time of order.
