产品概述:
ASP-150C光谱仪是多种不同光学应用理想选择,灵活可调和分辨率高。
ASP-150T型能够使用te ' 殊的旋转装置,能够得到更宽光谱范围的测量结果,不会降低分辨率。
ASP-150C体积小,可以放置在光学平台上,功能强,界面友好。ASP-150CF和ASP-150TF 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. |
