AOTF-echelle spectrometer for air-ICP-AES continuous emission monitoring of heavy metals and actinides

open access: yes, 1999
A spectrometer system consisting of a quartz acousto-optic tunable filter (AOTF) and an echelle grating has been assembled and tested for ICP-AES continuous emission monitoring of heavy metal and actinide elements in stack exhaust offgases introduced ...

Optical Alignment and Diffraction Analysis for AIRES: An Airborne Infrared Echelle Spectrometer

open access: yes, 2002
The optical design is presented for a long-slit grating spectrometer known as AIRES (Airborne InfraRed Echelle Spectrometer). The instrument employs two gratings in series: a small order sorter and a large steeply blazed echelle.
