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?？梢杂糜诙喾N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?？梢詼y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.
