HR2000+高分辨率微型光纤光谱仪
模块设计
HR2000+光谱仪5.85" x 4.13" x 1.65" (LWH) ，是第一个模块化光学平台的光谱仪，允许使用者选择光学台，如探测器，光栅和狭缝。光谱仪探测器的选择包括CCD阵列，UV
CCD阵列和用于NIR的阵列。光栅的选择包括300, 600, 1200, 1800和2400线/每毫米光栅。狭缝的选择包括, 10, 25,
50, 100或200 um。使用者也可选择光纤附件，如光源、探测器和光纤，配置不同的小尺寸、特殊应用系统。
AgPlus镜
在HR2000+光谱仪中可使用高反射率的AgPlus镜，用于弱光试验中的高分辨率测量。AgPlus镜可增加系统10-35%的灵敏度。定购AgPlus镜时参见SAG+UPG-HR。
方便的操作
HR2000+高分辨率光谱仪通过USB端口或串口与笔记本电脑或桌面电脑相连。每个光谱仪的波长校准系数编程到HR2000+的存储器片；操作软件从光谱仪读取这些值。通过USB端口与PC相连时，HR2000+高分辨率光谱仪不需要额外的电源。
每秒钟扫描1000个完整光谱
HR2000+光谱仪每个毫秒可以获取并存储一个全光谱数据(必须通过USB 2.0接口与电脑连接)。 HR2000+的主要特点是快速响应和高分辨率，适合于某些特定的化学生物应用。
程序控制器
HR2000+光谱仪有一个板载的程序控制器可对光谱仪及其附件进行控制。通过30针的接口，您可以进行许多操作包括控制外部光源，从外部对象获取数据。还提供10个可编程的数字I/O口连接到别的设备，一个模拟输出，一个模拟输入和一个信号发生器用于外部触发。
HR2000+样品光谱
使用的HR2000+光谱仪，以2ms间隔的采样速度采集的LS-1光源开启到稳定时的光谱变化，图中很好的说明了HR2000+光谱仪在快速采样过程中返回的巨大的数据量，它的最快采样速度是每秒1000幅光谱。
