产品概述：

微型光谱仪ASP-75体积小，重300g。设计简洁，覆盖光谱范围宽，分辨率高，体积小。可以用于多种的对空间要求严格的应用，以及OEM集成。

ASP-100MF型te ' 殊光纤输入，带有光谱狭缝，尺寸与探测器相适应。可以测量8个自由空间或光纤信号，无需重新对准。但是，不推荐使用光纤测量飞秒激光器的光谱，因为这会带来信号调制以及光谱畸变。

(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.
