SM304 InGaAs近红外光谱仪

SM304 InGaAs近红外光谱仪 SM304是一款高分辨率、宽动态范围、高信噪比的高性能科研级光谱仪，采用SM304 TE cooled InGaAs阵列探测器，适用于弱光源短红外测量。还采用TE制冷，确保了仪器长时间稳定的工作。应用SP公司特有的光路和电子系统，使暗噪声和杂散光控制到最小。最理想的测试范围是：900nm-2500nm。SM304可直接通过内置狭缝或经光纤耦合进光，支持标准可拆卸式接口SMA 905，FC光纤耦合器或者定制光纤接口。 光谱仪软件包括基于Windows的SM32光谱采集和分析软件，以及SDK和DLLs供客户自行开发产品特点：

科研级高性能非常低的暗电流和杂散光高动态范围和信噪比高稳定可通过狭缝和光纤输入多功能应用高速数据采集900-2500nm测试范围产品参数：
