The AOTF7N70 part of Alpha & Omega is an AOTF (acousto-optic tuneable filter) with a center wavelength of 7,000 nanometers. It is a compact, low-cost device designed for remote sensing and spectroscopic applications. It is designed to address broad wavelength of applications such as imaging and filtering. It is a high-speed, monolithic device with a Faraday rotator and electro-optic modulator. The device also has a very high extinction ratio, low voltage drive and low power consumption. The AOTF7N70 is a preferred choice by many remote sensing and spectroscopy researchers thanks to its low cost, fast tuning speed, and high extinction ratio.
