Brewer MkIII Spectrophotometer
The Brewer MkIII Spectrophotometer measures the total ozone column, sulphur dioxide and UV spectra using a double-monochromator optical system for improved stray light performance. Two-axis tracking, filter selection, wavelength calibration and data logging are managed by internal electronics and a host PC for 24-hour scheduled, unattended operation.

Overview
In detail
How it works
The Brewer MkIII uses a double-monochromator optical system that gives much-improved stray light performance over single-monochromator designs, providing near-simultaneous observations of the total ozone column, SO2 and UV spectra. Two-axis tracking, appropriate filter selection, on-board wavelength calibration and data logging are managed through internal electronics and an IBM-compatible host computer.
Operation
Control software on the host PC enables 24-hour scheduling and remote, unattended operation. The instrument is recommended by Environment Canada for its measurement of ozone and solar radiation in the UV spectrum, with high wavelength accuracy and excellent stray light reduction supporting long-term stability.
