5.3 MOTORIZED SLITS
A motorized slit assembly may be adjusted from 6 µm to 2 mm width in 6 µm steps. The slit width
is controlled through the utility software, optional hand controller, optional TracQ Basic software or
by using low level commands.
An advantage of using motorized slits is that in addition to setting the slit widths individually, the
software can be configured to an automatic bandpass setting. The software adjusts the slit widths
to maintain the chosen bandpass as scans are performed using multiple gratings and either output
port.
The mathematics involved in determining the slit width takes into account the input and output
focal lengths of the instrument’s design, as well as the angle of the grating at the specified
wavelength.
