mcs-ccd-lab 光谱系统系列:分別有 /uv 适用范围 200-600nm;/uv-nir 适用范围 200-980nm,可以用选择 usb2.0 或 pci 介面连接电脑,光道光纤线可选择标准sma连接器作光纤插头,系统的电子提供16-bit解象度,及感应器得到冷却,因此感应器的 综合时间(integration-time)可短至一分钟。内置的已测试及永固设计,新mcs-ccd跟mcs光谱感应器一样, 耐热性及抵御震颤,光谱仪的心藏有一个闪耀平场光栅作光的色散及成象,一个光学光纤横切面转换器作入囗狭缝及一个冷却ccd感应器。所有光学元件都永久被稳固於光谱感应器内,这技术结果是波长稳定,误差少过0.1nm及热转移少过0.01nm/k。
优点:
-
高灵敏性
-
低光度感应性
-
多元应用测量
-
电脑化及热稳定性
