Some measurements must be made practically instantaneously, such as logging or
monitoring changes in a spectrum from a process. This requires the simultaneous
detection
of
signals over a range of wavelengths. A linear detector such as a
PDA
positioned in the focal plane
of
the 270M can capture transient spectral distributions
. with a time resolution that depends only on the readout
or
gating time
of
the detection
system.
To set up for this scenario, the light from the process is coupled via an optical fiber
to
the entrance slit.
to
minimize coupling loss,
an
optional fiber optic interface is used
to
aperture match the fiber
to
the spectrometer. The QuikScan PDA detector is mounted
at the focal plane in the exit of the 270M.
