(1) - the necessary width and center of the registered range should be specified when placing an order. The ASP-150T has an operational range adjustment function;
(2) - each spectrometer is equipped with a fiber socket and allows measurement of either free-space or fiber signals without any realignment;
(3) - any array can be combined with any grating type;
(4) - sensitivity given at the wavelength of 550 nm;
(5) - the Hamamatsu arrays provide for sensitivity control via special driving signal, that can set either low (values in brackets) or high sensitivity mode;
(6) - the property of the CCD to prevent the charge flow from the neighboring overexposed pixels;
* - values given for the Toshiba 1304DG CCD array.
