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

(b) The switching speed depends upon the initial and final wavelength. See the Performance Plots 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 the manual for details.
