Free Space Acousto-Optic Tunable Filters
The Brimrose Acousto-Optic Tunable Filter (AOTF) is a solid state acousto-optic device with no moving parts. It functions as a tunable transmissive filter. It is able to precisely and rapidly adjust the wavelength, and intensity of the diffracted/filtered light by varying the RF power.
Brimrose offers both standard and custom AOTFs. AOTFs are used widely in numerous optical systems and applications, especially in industrial or process control near-infrared (NIR) spectroscopy applications.
SPS/SPF PC Controlled AOTF Drivers
The SPS and SPF AOTF Controllers are high performance, RF frequency generators. They provide fast frequency sweep (up to 16,000
l/sec) using a direct digital synthesizer incorporated into a self-contained case with AC power supply. Standard units are provided in laboratory enclosures with one, four or up to eight RF output channels.

Brimrose uses a crystal of Tellurium Dioxide (TeO2) AOTF that operates in the NIR region in a so-called non-collinear configuration - the acoustic and optical waves propagate at quite different angles through the crystal.
Material: TE – Tellerium Dioxide (350-5000 nm) QZ – Quartz (SiO2)
Options: S – Standard Resolution H – High Resolution
EH – Extra high Resolution UH – Ultra high Resolution
The SP Model AO Controllers are high performance RF frequency synthesizers incorporated into a self-contained case with AC power supply. A modular cable with a DB9 connector interface allows frequency control via the Personal Computer USB port (Serial RS232 optional). Using simple commands with any terminal (modem) program (such as ProComm) allows the user to set any frequency from the computer keyboard. In addition, included with the unit is a frequency control program that can be used with any IBM PC computer.
