(a) Devices measured using 635 nm light and 650 - 1050 nm AR-coated protective window.

(b) Maximum Extinction Frequency Limit is defined as the frequency of the device above which the maximum extinction of the beam as noted on the data sheet is no longer attained.

(c) The maximum operating voltage is labeled on each unit and also in the data sheet that comes with each unit.

(d) The maximum extinction voltage, which is always below the max operating voltage, varies depending on the wavelength of interest, angle, and device. Each unit ships with a data sheet that notes the optimal voltage settings and associated extinction ratios for normal incidence.

(e) View Manual for detailed specifications on the substrate.
