双单色仪CM112 DK242

CM112和DK242可以在出厂时就设置为色散相加或相减模式的双单色仪。在两个模式里，两个单色仪像一个双重滤波器来消除散射光，效果是单单色仪的平方倍。在色散相加模式，双单色仪等效与一个双倍焦距单色仪，但可以更多的减少散射光。DY个光栅传播的光谱产生一个角度范围，第二个光栅加倍了这个角度范围，这样，双单色仪产生的分辨率是单个单单色仪的两倍。在相减色散模式中，DY个单色仪选择带通，第二个单色仪移除因为DY个单色仪引起的时间和角色散的误差。

CM112是一款可双向光栅驱动扫描，自动选择波长，双光栅塔台结构的紧凑型双级联单色仪，产品尺寸：约13x16x8cm；

DK242是一款可双向光栅驱动扫描，恒定光谱分辨率，两个三光栅塔台结构的双级联单色仪；

通过RS232连接电脑，是一种完全计算机控制的双级单色仪。CM112具有色散相加和色散相减两种模式。色散相加模式可以双倍提高光谱分辨率，适合高分辨率测量；色散相减模式，有效降低了单色仪杂散光，杂散光YZ极强，从而能进行更微弱信号的探测，如拉曼光谱、光电探测器光谱响应度标定等。色散相减模式只可以作单色仪使用，色散相加模式既可以作单色仪，又可以作光谱仪（可直接连接CCD）使用。在实际使用过程中需特别考虑光栅的选择。所有设备在出厂前均严格的定标，操作软件操作十分简单方便。
