The Dynamic Tunable Bandpass Filter adjusts the center
wavelength of a narrow band of light over a 100 - 200nm range. It
offers very high resolution of ~1.5nm and either single or simultaneous
multiple wavelength selection. It is able to precisely and rapidly adjust
the wavelength and intensity of the diffracted/filtered light by varying
the frequency (see graph) and RF power.
Brimrose offers both free-space and fiber-coupled configurations.
AOTFs are used widely in numerous optical systems and applications,
especially in industrial or process control near-infrared (NIR)
spectroscopy applications.

SPS/SPF II Model AOTF Controller System

APPLICATIONS
• Dense WDM Transmission Systems
• Laboratory Test and Measurement Systems
– tuning the center wavelength of broadband
sources (white light sources or LEDs)
• Other OEM Applications

Brimrose offers AOTF RF drivers compatible
with our AOTF devices. Our AOTF drivers
include SPF II drivers, which can control up to
four RF output channels, and SPS drivers,
which can control up to eight RF output
channels. Changing the RF level will vary the
intensity of the light being diffracted/filtered.
