HR2000+光谱仪采用预先配置好的HC-1光栅，具有革命性的预配置设计可提供波长范围在200-1100nm的全光谱输出。HR2000+CG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。
特点：
-
宽的波长范围(200-1100 nm)
-
高分辨率在全波长(200-1100 nm)的范围半高峰宽也可达到1.0nm
-
可编程微控制器

200-1100 nm 波长范围, 1.0 nm 分辨率
HR2000+CG光谱仪采用5微米狭缝，专利的HC-1光栅和消除二，三级衍射的滤光片可覆盖200-1100 nm的波长范围，光学分辨率可达到1.0 nm FWHM。HR系列光谱仪采用Sony ILX511B 2048像素探测器可获得高速和高分辨率特性。OFLV-200-1100滤光片安装在探测器前可消除二，三级衍射。
复合光栅&滤光片
HR2000+CG使用HC-1光栅，它是一种专利的可变闪耀波长光栅，提供的波长范围为200-1100nm。HR2000CG光谱仪还采用了OFLV-200-1100可变长通滤光片以消除二级和三级衍射的影响。光栅和滤光片在出厂时就已经安装并固定。
程序微控制器
HR2000+CG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。
