(a) The bandpass width increases linearly with wavelength. See the Performance Plots manual for details.

(b) The switching speed depends upon the bandpass width setting and the initial and final wavelength. See manual for details.

(c) Typical transmission for input light polarized parallel to the filter's transmission axis.

(d) The power density of your beam should be calculated in terms of W/cm. Please see manual for details.
