S1024DW大阱深探测器光谱仪采用1024像元光电二极管阵列探测器，用于需要高信噪比的测量。通过S1024DW可以观察到小于0.00001个吸光度单位的变化，适合高亮度的应用。（X"选项：超大阱深探测器）

 

 

S1024DW是标准阱深光谱仪，其二极管阵列探测器的信噪比为 2500：1。S1024DWX具有更大的阱深，信噪比为8000：1。

 

 理想的高光强应用光学平台

 

 S1024DW采用"USB"（也称作"S"）系列光谱的光路结构，可以根据具体不同的应用来配置光路。具体选项有入射孔径、探测器附件、滤光片及光栅等等。

 

 S1024DW光学平台的操作和USB4000光路结构很相似。

 

 S1024DW光路结构通过光纤采集光信号并经光栅分光到1024个高灵敏度光电二极管组成的阵列上，而在USB4000中采用的是3648像元的CCD阵列。

 

可集成的系统，适合多点采样 

在S1024DW光谱仪的主通道上可以附加多至7个辅助通道用以 多点采样，可以用来扩展探测的波长范围或监视参考光谱。所有通道都通过一个ADC1000-USB A/D转换器进行数据采集，每个通道轮流工作，总共8个光谱仪通道的数据同时采集。ADC1000-USB转换器通过USB接口连接S1024DW到PC。可以分开购买S1024DW和ADC1000-USB，或同时作为一个整体（S1024DW-USB）购买。
