Brimrose's core Acousto-Optic Tunable Filter (
AOTF) technology is being used in the spectrometer.
Abbreviations: objective lens (OBJ), easySTED waveplate (WP), tube lens (TL), dichroic beamsplitter (DC), band pass filter (BP), avalanche photo diodes (APD1, APD2), acousto-optic modulator (AOM), acousto-optic tunable filter (
AOTF), computer with FpGA based electronics board (PC w/FPGA).
The
AOTF modulated 4-laser unit, which provides as many as seven laser lines (choices from 405nm, 440nm, 457nm, 488nm, 514nm, 543nm, 562nm and 638nm), the AOM modulated 3-laser unit, which provides an additional three laser lines, and an optional picosecond or faster pulsed laser are just three of the laser options available.
The SpotCheck NIR, an acousto-optic tunable filter-based spec (
AOTF) from Infrared Fiber Systems, is about the size of a video camera.
An acousto-optic tunable filter (
AOTF) is a good choice for the complementary system because it is easily integrated into a DIAL system.
Product information is now available on a line of Acousto-Optic Tunable Filter (
AOTF) Film and Thin Film Analyzers from Brimrose Corporation.
