產品概述:
微型光譜儀ASP-75體積小,重300g。設計簡潔,覆蓋光譜范圍寬,分辨率高,體積小。可以用于多種的對空間要求嚴格的應用,以及OEM集成。
ASP-100MF型te ' 殊光纖輸入,帶有光譜狹縫,尺寸與探測器相適應。可以測量8個自由空間或光纖信號,無需重新對準。但是,不推薦使用光纖測量飛秒激光器的光譜,因為這會帶來信號調制以及光譜畸變。

(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. |
